While trying to work out for auto failover, I came across this situation which I couldn?t figure out.
Two test dsl connection for a particular site. EIGRP is used between the core and the primary link and static routes with higher AD(215) is used for secondary link.
The idea is, to route the traffic via secondary link with a higher AD when the primary link goes down.
Initially things go fine. The system routs the traffic via the primary link. Once the PPP session goes down, EIGRP looses the neighbor relationship and the traffic is getting routed via the secondary link which is normal.
But, even after the primary link gets restored, the traffic is getting routed via the secondary link and its not switching back to the primary link which should doo.
Note : Attached the sample setup.
