EIGRP Failover not working

cezar.sofian
Level 1
Level 1

Hi,

We have 3 routers connecting the office - servers - dr in a triangle, all running eigrp to advertised connected networks...see attached picture

The problem is when the link between the office and the server farm fails traffic should go through dr and reach the servers, but it doesnt. When it happens the DR networks have access to Servers networks, also OFFICE networks have acces to DR networks. I've already tried with floating static route with no luck.

Please see part of the configurations below...just ignore crypto incomplete commands

Any help would be appreciated

Can you post the route-map EIGRP_OUT from the DR router? If you look at the eigrp topology table on all three routers, does each router have two paths for each subnet?

ip access-list standard EIGRP_OUT

No ... only 1 route

Hello

Why redistribute connected and static and all 3 sites eigrp stubs?

If redistribute is the wqy you want to go with stub areas try a route map with default originate and allowed redistributed routes also
