![]() Thank You For Your Time And Best Of Luck! Thus, If RIP Is Being Redistributed Into EIGRP, The Routing Table Must Have An Entry For The.īelow I’ll try to list what I consider a best practice design of today’s enterprise networks.OSPF, EIGRP, BGP? Which one to use?Golden rule is to always use a protocol where it was designed to be used. R4(config)#router eigrp 200 R4(config-router)#redistribute bgp 200 metric 1 1 1 1 1. So we should redistribute BGP into EIGRP on R4 and make sure R5's loopback can reach PE1's prefixes, which just happens to be the next task to complete. ![]() When and how to use a particular protocol.And since the latter is often an acquired skill, a lot of not-so-lucky engineers end up with wrong ideas and conceptsin the heads. ![]() However, one thing often overlooked is the routing protocols best practice design,i.e. I think the reason for thatis that people have generally been concentrated on learning about the routing protocol, how it works, all the knobs you can twistto influence a routing decision logic. It certainly takesa good engineer to understand how it works and even that can take up to several hours. What motivated me to write this post is a state of the IP routing of some of the enterprise networks I’ve seen.A quick show ip route command reveals a non-disentanglable mixture of dynamic and static route with multiple points of redistribution and complex,rigid filtering rules, something you’d only see in your bad dream or a CCIE-level lab. ![]()
