EIGRP and Overlapping Addresses

We have a customer that connects to us over frame with two pvc's to two of our sites. One pvc to each site. The customers remote network ip addresses overlapped our local ip addresses so we had to setup dynamic and static NAT on their routers. The inside interface of the customers router is set as inside nat and the serial interface with the frame, is setup as outside nat. Floating static routes are being used to control failover. We want to setup EIGRP but I dont know of a way to have EIGRP advertise the translated addresses to us versus having the overlapping addresses advertised. Does anyone know how to do this or if it is even possible? Thanks.


Re: EIGRP and Overlapping Addresses

1. Create a static route for the NATed network on the customer router.

2. Enable EIGRP on the serial link. (IF the serial and lan of the customer are from the same subnet, then EIGRP will get enabled on both serial and lan networks. To prevent the non-NATed lan address, from being distributed through EIGRP, use a distribute-list preventing the lan network, from being advertised)

3. Redistribute the static route under EIGRP using "redistribute static " command.

Hope this helps!
