RE: eigrp and sec address [7:12087]
I may be misunderstanding your topology...it would help if you posted config excerpts. As far as my experience has been, secondary addresses are configured in eigrp in the same way as primary addresses. Just make sure you've included the router eigrp [network#] and network xx.xx.xx.xx commands on the relevant router. Both routers need to be using eigrp and having the same autonomous system number in order to see each others updates (unless you are redistributing routes, but I won't get into that). Post your config and the group will be better able to see what's up, ok? -Mark A.

Re: eigrp and sec address [7:12087]
Javier, EIGRP will support secondary addresses. However, neighbor relationships will NOT be formed with the secondary addresses. Refer to: http://www.cisco.com/warp/customer/103/eigrpfaq.html#Q1.3 A good white paper on EIGRP can be found at: http://www.cisco.com/warp/customer/103/eigrp1.html I found on the Cisco site, a way to get around not getting any routing updates from the secondary IPs If an interface is configured with secondary IP addresses, split horizon rules can affect whether or not routing updates are sourced by these secondary addresses. If the primary and secondary IP address network numbers belong to the same network class, routing updates source by the secondary address are suppressed unless split horizon is disabled. If the primary and secondary addresses do not belong to the same network class, routing updates sourced by the secondary address are not suppressed. So it looks like if you disable split horizon you will send and receive the routing updates but not form neighbor relationships. Hope this helps. Debbie --- Javier A.
