With EIGRP you can implement areas similar to OSPF or ISIS. You would want to keep subnets with in the same EIGRP "area". Just configure routers with different EIGRP #'s and send summary updates into the different areas.
I know a very very very large network doing this. ^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^- Bill Carter CCIE 5022 "To accomplish great things, we must not only act, but also dream; not only plan, but also believe. -Anatole France ^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^-^- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kim Edward B Sent: Tuesday, October 23, 2001 3:06 PM To: [EMAIL PROTECTED] Subject: RE: which is the best [7:23902] If it is cisco only environment, I would prefer EIGRP. Less CPU and Memory requirement (which means less expensive routers in some cases and also more free CPU and Memory for the routers). Also I believe they have better convergence time than OSPF. As Mr. Lupi mentioned, while OSPF's metric is based on bandwidth, the EIGRP can be based on (bandwidth, delay and also MTU, load, reliability as necessary). For example, if you have F/R of 512K and 256K, OSPF will use the 512K. You could make it to use the 256K to load balance by the bandwidth statement but it won't be really true load balancing. EIGRP can via variance and other ways. Con is the proprietary Routing protocol. In the future if you acquire non cisco network, you could still use the redistribution. So if you have only cisco network, I would prefer EIGRP. Lastly, OSPF's more hierarchical design than EIGRP(OSPF areas, stubby, total and not so stubby, etc) can scale better in bigger network, but for the given router numbers (50), EIGRP fits better in my opinion. I don't know what I'm trying to say here... For the given condition, I would go with EIGRP, but if you are planning to expand and also possibly acquire non-cisco routers OSPF might be better. Sorry for the confusion. My .02 cents.

Your decision would have to be based on your needs also, EIGRP has a couple of features that OSPF does not that you may want, such as load balancing across links that do not have equal metrics.
