In this video you will learn how to filter routes in ospf With #distribute-list commnad we can combine with ACL,route-map or prefix so you can watch and learn.
In this video you can learn the concept of OSPF virtual link, see the configuration and verification. I hope you enjoy the topic.
In any routing protocol, scalability is an essential factor. When we split the OSPF routing domain, we are trying to reduce the size of each area's LSDB.
when we check the global rib table with #show ip route command, we see that there is an "E2" ("N2") / "E1" ("N1") sign in front of the external route.
In this video,I tried to explain how SPF calculate shortest path, loops free! This part is for only point-to-point links.
In this article I want to talk about OSPF Multi-Area solution. OSPF uses the concept of area, and the area is like a subdomain. When a router interface is in a specific area, it maintains the topology information of that area.
