OSPF Areas and OSPF Types of Routers - Practical OSPF - Lesson 2
Ғылым және технология
Understanding OSPF design requires understanding OSPF Areas. And to truly understand OSPF areas, you must understand OSPF types of Routers. We'll be explaining both of these concepts in this lesson.
OSPF allows for a two-tier hierarchy with Area 0 (the backbone area) at the top, and every other area connected through Area 0. This creates a Hub and Spoke area design.
Routers in OSPF are labeled based upon where they sit in the Area design. There are four types of OSPF Routers: Internal Routers, Backbone Routers, Area Border Routers (ABR), and Autonomous System Border Routers (ASBR). In this lesson we'll be illustrating the roles and functionalities of each of these Routers.

Thanks for this great series. I have a question though (two cases), 1- You said if we put a router between Area 88 and Area 99 there could be a loop, aren't OSPF a loop-free protocol? 2- What would happen if we do the same but with adding Area 0 so the router would belong to the three areas 88, 99, and 0?
One quick question Ed, regarding the re-distributed routes into OSPF, will only apply to IGP routing protocols or will be also the case of iBGP or eBGP into OSPF Router 7 in the topology illustrated as the Autonomous System Border Router? Thank you in advance.

Hi Jair. You can redistribute _any_ category of routes into OSPF. To include BGP routes. Even Static & Directly Connected routes. Even from one OSPF process into another OSPF process. Any redistribution whatsoever creates an ASBR.
Hi bro u said in this video that area border routers are responsible maintain LSDB and summarize the LSA is that the same what (DR) Do?
@PracticalNetworking

No, not really the same. THe DR is the "messaging center" for a particular link, and doesn't do any abstraction of knowledge between areas/links. More details in these videos: - kzread.info/dash/bejne/qX2Io8eIaMyfhZc.html - kzread.info/dash/bejne/f51n1rCMhc3IZ5s.html

I don't know if this is simply a misfortunate translation, or an actual call for help. If the latter... Roman, then I'd urge you to tread carefully. We all fall on tough times. Certain personality types are more susceptible to darker thoughts, it's the burden some of us are forced to carry. But realize you _can_ carry it. You _have been_ carrying it. And you are strong enough to _continue_ to carry it. You are a gift to the world, and you have gifts to _give_ to the world. Your story matters, you matter. Please seek help if you need it. With love, from another corner of the world.
Great video! Thank you!
