In this video we're going to take a look at OSPF.
Open Shortest Path First (OSPF) is a widely used and supported routing protocol.
It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It also falls under the category of Link-state routing protocols.
Routers running OSPF learn about the enter network in order to create routes. They do this by flooding Link State Updates. There are three steps to the process.
Become neighbours - Two routers running OSPF on the same link agree to form a neighbour relationship
Exchange database information - The neighbouring routers swap their LSDB information with each other
Choose the best routes - Each router chooses the best routes to add to its routing table based on the learned LSDB information

In this video, Keith Barker covers OSPF, the protocol that makes it possible for your routers to forward traffic all the way through your network. There are a lot of different topics to deal with when you break down OSPF, but Keith covers them with easy examples and simple demonstrations:
• Start off with a sample network topology to visualize how OSPF works on it
• Breaking down how LSAs make OSPF possible
• How Link State Databases provide routers with all the network information they need
• OSPF Hello messages and how they help routers share data
Visualizing the sort of network that OSPF would be useful for can help understand exactly how it does that. Keith starts with a sample network topology and splits it into areas. Different routers provide access to different areas, and eventually they'll become OSPF neighbors.
But before you get to that, it's important to understand Link State Advertisements (LSA). When you have a network topology with multiple zones, the connecting routers are responsible for creating an LSA and broadcasting them. LSAs contain all the information about the networks that each router services.
With OSPF, it's possible for routers to "meet" one another, send "hello"s to one another and share their link state information. Link State Databases are shared between OSPF routers, and in turn those routers leverage the data inside those databases to make decisions about routing data across the entire network.
OSPF is the language that makes it possible for all the routers across a network to collaborate like this. It also makes it possible to carve the network up into smaller chunks so that you don't have to create routing tables for every last destination in the network on every single router.

In this video, CBT Nuggets trainer Jeremy Cioara explains Open Shortest Path First (OSPF) areas and Link State Advertisement (LSA) types. This is a blisteringly fast introduction to OSPF Areas and LSA types, crucial and complicated topics if you're dealing with OSPF configurations.
If you're dealing with OSPF configurations, you're dealing with Areas and LSAs.
When you begin with OSPF configurations, you must create Area 0. Some businesses never grow beyond this so-called backbone area. But as the business begins to grow and you begin adding more routers, your routing table can get pretty unruly.
If there are too many routes, too many changes with networks going up and down, or processor cycles getting wasted, it’s important to break into multiple areas.
In Link State Protocol, all routers in the area must have the same link-state database. The only way to hide routes or do route summarization is to break into multiple areas.
Different areas include Stubby, Totally Stubby and Not-So-Stubby Areas. Yes, that's actually what they're called.
Stub area is where you have an area that’s limited in what information can receive. Cisco allows for totally stubby areas which makes traffic highly efficient. A not-so-stubby area camouflages external routes for the sake of expediency.
LSAs interact with the traffic and only some areas permit different LSAs. See which with Jeremy's explanation.

Open Shortest Path First
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4. The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 (2008).
OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. Intermediate System to Intermediate System (IS-IS), another link-state dynamic routing protocol, is more common in large service provider networks. The most widely used exterior gateway protocol is the Border Gateway Protocol (BGP), the principal routing protocol between autonomous systems on the Internet.
Overview
OSPF is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets solely within a single routing domain, such as an autonomous system. It gathers link state information from available routers and constructs a topology map of the network. The topology is presented as a routing table to the Internet Layer which routes datagrams based solely on the destination IP address found in IP packets. OSPF supports Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) networks and features variable-length subnet masking (VLSM) and Classless Inter-Domain Routing (CIDR) addressing models.

In this video, Keith Barker covers OSPF, the protocol that makes it possible for your routers to forward traffic all the way through your network. There are a lot of different topics to deal with when you break down OSPF, but Keith covers them with easy examples and simple demonstrations:
• Start off with a sample network topology to visualize how OSPF works on it
• Breaking down how LSAs make OSPF possible
• How Link State Databases provide routers with all the network information they need
• OSPF Hello messages and how they help routers share data
Visualizing the sort of network that OSPF would be useful for can help understand exactly how it does that. Keith starts with a sample network topology and splits it into areas. Different routers provide access to different areas, and eventually they'll become OSPF neighbors.
But before you get to that, it's important to understand Link State Advertisements (LSA). When you have a network topology with multiple zones, the connecting routers are responsible for creating an LSA and broadcasting them. LSAs contain all the information about the networks that each router services.
With OSPF, it's possible for routers to "meet" one another, send "hello"s to one another and share their link state information. Link State Databases are shared between OSPF routers, and in turn those routers leverage the data inside those databases to make decisions about routing data across the entire network.
OSPF is the language that makes it possible for all the routers across a network to collaborate like this. It also makes it possible to carve the network up into smaller chunks so that you don't have to create routing tables for every last destination in the network on every single router.

Watch the full OSPF course: https://courses.cbt.gg/t5e
In this video, Keith Barker covers OSPF, the protocol that makes it possible for your routers to forward traffic all the way through your network. There are a lot of different topics to deal with when you break down OSPF, but Keith covers them with easy examples and simple demonstrations:
• Start off with a sample network topology to visualize how OSPF works on it
• Breaking down how LSAs make OSPF possible
• How Link State Databases provide routers with all the network information they need
• OSPF Hello messages and how they help routers share data
Visualizing the sort of network that OSPF would be useful for can help understand exactly how it does that. Keith starts with a sample network topology and splits it into areas. Different routers provide access to different areas, and eventually they'll become OSPF neighbors.
But before you get to that, it's important to understand Link State Advertisements (LSA). When you have a network topology with multiple zones, the connecting routers are responsible for creating an LSA and broadcasting them. LSAs contain all the information about the networks that each router services.

Start your free week with CBT Nuggets. https://cbt.gg/2LZhF9F
In this video, CBT Nuggets trainer Jeremy Cioara explains Open Shortest Path First (OSPF) areas and Link State Advertisement (LSA) types. This is a blisteringly fast introduction to OSPF Areas and LSA types, crucial and complicated topics if you're dealing with OSPF configurations.
If you're dealing with OSPF configurations, you're dealing with Areas and LSAs.
When you begin with OSPF configurations, you must create Area 0. Some businesses never grow beyond this so-called backbone area. But as the business begins to grow and you begin adding more routers, your routing table can get pretty unruly.
If there are too many routes, too many changes with networks going up and down, or processor cycles getting wasted, it’s important to break into multiple areas.
In Link State Protocol, all routers in the area must have the same link-state database. The only way to hide routes or do route summarization is to break into multiple areas.
Different areas include Stubby, Totally Stubby and Not-So-Stubby Areas. Yes, that's actually what they're called.
Stub area is where you have an area that’s limited in what information can receive. Cisco allows for totally stubby areas which makes traffic highly efficient. A not-so-stubby area camouflages external routes for the sake of expediency.
LSAs interact with the traffic and only some areas permit different LSAs. See which with Jeremy's explanation.

Лекция по протоколу маршрутизации OSPF (Open Shortest Path First). Страница курса "Компьютерные сети" - https://www.asozykin.ru/courses/networks_online
Протокол OSPF (Open Shortest Path First):
- Протокол с учетом состояния канала (link-state protocol)
- Используется алгоритм Дейкстры (Shortest Path First)
- Передача данных через IP, код протокола 89
Особенности OSPF:
- Децентрализованный глобальный алгоритм
- Расчёт стоимости путей после получения полной информации о сети
Этапы работы протокола OSPF.
1. Изучение топологии сети:
- Маршрутизаторы изучают подключенные сети и ближайших соседей
- Информация о топологии распространяется по всей сети с помощью лавинной рассылки (flooding)
2. Расчет стоимости маршрутов в сети:
- Выполняется после того, как будет известна полная конфигурация сети
- Каждый маршрутизатор выполняет расчет самостоятельно
3. Обновление информации о конфигурации сети:
- Маршрутизаторы проверяют доступность соседей
- Рассылка информации об изменении конфигурации сети

In this video we're going to take a look at OSPF.
Open Shortest Path First (OSPF) is a widely used and supported routing protocol.
It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It also falls under the category of Link-state routing protocols.
Routers running OSPF learn about the enter network in order to create routes. They do this by flooding Link State Updates. There are three steps to the process.
Become neighbours - Two routers running OSPF on the same link agree to form a neighbour relationship
Exchange database information - The neighbouring routers swap their LSDB information with each other
Choose the best routes - Each router chooses the best routes to add to its routing table based on the learned LSDB information

In this video, Keith Barker covers OSPF, the protocol that makes it possible for your routers to forward traffic all the way through your network. There are a lot of different topics to deal with when you break down OSPF, but Keith covers them with easy examples and simple demonstrations:
• Start off with a sample network topology to visualize how OSPF works on it
• Breaking down how LSAs make OSPF possible
• How Link State Databases provide routers with all the network information they need
• OSPF Hello messages and how they help routers share data
Visualizing the sort of network that OSPF would be useful for can help understand exactly how it does that. Keith starts with a sample network topology and splits it into areas. Different routers provide access to different areas, and eventually they'll become OSPF neighbors.
But before you get to that, it's important to understand Link State Advertisements (LSA). When you have a network topology with multiple zones, the connecting routers are responsible for creating an LSA and broadcasting them. LSAs contain all the information about the networks that each router services.
With OSPF, it's possible for routers to "meet" one another, send "hello"s to one another and share their link state information. Link State Databases are shared between OSPF routers, and in turn those routers leverage the data inside those databases to make decisions about routing data across the entire network.
OSPF is the language that makes it possible for all the routers across a network to collaborate like this. It also makes it possible to carve the network up into smaller chunks so that you don't have to create routing tables for every last destination in the network on every single router.

In this video, CBT Nuggets trainer Jeremy Cioara explains Open Shortest Path First (OSPF) areas and Link State Advertisement (LSA) types. This is a blisteringly fast introduction to OSPF Areas and LSA types, crucial and complicated topics if you're dealing with OSPF configurations.
If you're dealing with OSPF configurations, you're dealing with Areas and LSAs.
When you begin with OSPF configurations, you must create Area 0. Some businesses never grow beyond this so-called backbone area. But as the business begins to grow and you begin adding more routers, your routing table can get pretty unruly.
If there are too many routes, too many changes with networks going up and down, or processor cycles getting wasted, it’s important to break into multiple areas.
In Link State Protocol, all routers in the area must have the same link-state database. The only way to hide routes or do route summarization is to break into multiple areas.
Different areas include Stubby, Totally Stubby and Not-So-Stubby Areas. Yes, that's actually what they're called.
Stub area is where you have an area that’s limited in what information can receive. Cisco allows for totally stubby areas which makes traffic highly efficient. A not-so-stubby area camouflages external routes for the sake of expediency.
LSAs interact with the traffic and only some areas permit different LSAs. See which with Jeremy's explanation.

Лекция по протоколу маршрутизации OSPF (Open Shortest Path First). Страница курса "Компьютерные сети" - https://www.asozykin.ru/courses/networks_online
Протокол OSPF (Open Shortest Path First):
- Протокол с учетом состояния канала (link-state protocol)
- Используется алгоритм Дейкстры (Shortest Path First)
- Передача данных через IP, код протокола 89
Особенности OSPF:
- Децентрализованный глобальный алгоритм
- Расчёт стоимости путей после получения полной информации о сети
Этапы работы протокола OSPF.
1. Изучение топологии сети:
- Маршрутизаторы изучают подключенные сети и ближайших соседей
- Информация о топологии распространяется по всей сети с помощью лавинной рассылки (flooding)
2. Расчет стоимости маршрутов в сети:
- Выполняется после того, как будет известна полная конфигурация сети
- Каждый маршрутизатор выполняет расчет самостоятельно
3. Обновление информации о конфигурации сети:
- Маршрутизаторы проверяют доступность соседей
- Рассылка информации об изменении конфигурации сети

Open Shortest Path First
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4. The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 (2008).
OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. Intermediate System to Intermediate System (IS-IS), another link-state dynamic routing protocol, is more common in large service provider networks. The most widely used exterior gateway protocol is the Border Gateway Protocol (BGP), the principal routing protocol between autonomous systems on the Internet.
Overview
OSPF is an interior gateway protocol (IGP) for routing Internet Protocol (IP) packets solely within a single routing domain, such as an autonomous system. It gathers link state information from available routers and constructs a topology map of the network. The topology is presented as a routing table to the Internet Layer which routes datagrams based solely on the destination IP address found in IP packets. OSPF supports Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) networks and features variable-length subnet masking (VLSM) and Classless Inter-Domain Routing (CIDR) addressing models.

BGP vs. OSPF: When to use each protocol
Border Gateway Protocol, or BGP, and Open Shortest Path First, or OSPF, are two of the most popular, standards-based dynamic routing protocols used around the world. Although BGP and OSPF are both dynamic routing protocols and perform similar tasks, they calculate their routing decisions and advertise routes in different ways.
