Enabling eigrp is the same as with most other routing protocols: router eigrp 10 network 10.1.0.0 network 192.168.5.0 network x.x.x.x We don't use EIGRP ourselves, and I don't have a huge amount of experience with it personally (other than lab study). I'm not aware of anyone using it (not that this means anything - as far as I know everyone in the country could be). EIGRP is often referred to as a balanced-hybrid routing protocol, in that it displays properties of both distance vector and link state protocols. Unlike distance-vector (eg RIP), EIGRP does not indiscriminately fire routing updates across the 'net; unlike link-state protocols, EIGRP treats everything as one large area. Because of this, EIGRP can become more troublesome to manage in larger internetworks: care must be taken to design a network which does not destabilise easily. OSPF does a nice job of reducing this complexity by making it intuitive to break a network into individual areas, and (essentially) routing between them; the process with EIGRP is rather more manual. Routing information can be summarised at router interfaces, creating a similarly hierarchical topology. Good initial network design can eliminate many problems from the beginning. PS - like I said, I don't have a lot of experience with EIGRP first-hand - most of what I say here is inferred through study or research. Regarding your last question: if you only have the one connection to the outside world (eg your hypothetical frame), you don't need to run any routing protocol over it. Your router (the 2500) only needs a default router pointing to the appropriate next hop - how the next hop decides how to forward packets you send it is irrelevant, as far as you are concerned. You can be using RIP, your provider could use OSPF. Just as long as they get where they are supposed to. Of course, the situation becomes far more interesting with two upstream pipes... -- Regards, Thomas Salmen Network Manager Radionet Ltd. 72 Paul Matthews Road Albany, Auckland, New Zealand Ph: +64 9 4140 300 -----Original Message----- From: Malcolm Lockyer [mailto:hivemindhivemind(a)hotmail.com] Sent: Saturday, 2 March 2002 7:47 p.m. To: nznog(a)list.waikato.ac.nz Subject: Semi OT: Anybody using the EIGRP protocal? Hello all.. I was messing 'round on amazon (reading all the book exerpts :P) and in a cisco book I found some stuff about EIGRP routing protocal. What I read about it, it sounded really good, like had all the benifits of OSPF and uses less CPU power, and easier to setup etc. So, I was just curious, is anybody in NZ using EIGRP? Oh, and I'm a stupid newbie, so I'm sorry if the next few questions are kind silly, but, I guess everybody has gotta start somewhere.. :P I've only worked with cisco 2500's, so this may be totally off for the newer routers, but... When configuring the 2503 and 2514 with IOS 12.0, it seems that the only protocals it, "likes" is RIP and IGRP, say if I wanted to use EIGRP is it just a matter of saying somthing like "ip EIGRP" on the interfaces, or do you have to do somthing like upgrade to an IOS with EIGRP included? Also I was wondering, say I had a mid sized network, and I decided that I wanted to use, EIGRP protocal on my network. But, say, I was getting internet delivered over frame relay, and that service provider was using, say RIP. Would that work? Or do you need to do somthing special to the routers to allow somthing like that, data moving between routing protocals??
