Dude, you dont know how many times Ive gone over the OSPF chapters in the CCNP cert guide and my eyes glazed over. This whole series just set me straight. You kept it simple and straight to the point! THANK YOU!

[@PracticalNetworking]

That was my whole intention =) To teach OSPF in a more approachable way. Glad you enjoyed it. Thanks for the kind words.

[@---usr]

Holy moly! This is the best explanation about OSPF I found so far! We need a full CCNA course with Cisco packet tracer labs ❤ I beg you sir 🙏🙏

[@PracticalNetworking]

Amazing ....

[@shadisaleh7316]

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?

[@محمدجابر-غ1ن6خ]

nice thank you mate

[@sergioalcantar3290]

These are tiny bit-sized chunks of knowledge, so easy to digest...

[@The--J0ker]

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: - kzbin.info/www/bejne/rXq3cpiFbc5si5Y - kzbin.info/www/bejne/g5qWpYGJis-VbZo

[@VyyMokodompit]

Aghh.. Very Nice

[@jairunet]

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.

[@PracticalNetworking]

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.
