Hi John,
The static route will not fail so you need to make it "float". This
means giving it a higher AD than EIGRP (90/170). Doing this will make
the EIGRP learned path preferred over the static. When the EIGRP route
goes away, then the static will be installed into the routing table
automatically and traffic will start to flow through C-X.
Once the EIGRP route comes back, it will be placed in the routing table
and the static route will be removed and traffic will flow through B
again instead of C-X.

Subject: EIGRP and Static Routing failover
Hi All,
I have a router A that connects to Router B and Router C. Router B in
turn connects to another Router D. Router C also connects to Router D
but via another router X.
Hence there are 2 paths on the network from router A to router D
i.e Path1: A ----- B -------- D and Path 2: A -------- C
-------X
-------D
Path 1 has EIGRP configured all the way for all networks i.e Router A
runs Eigrp with router B which also runs eigrp with router D
Path 2 has static routing configured all the way for all networks
Routing works perfectly fine with both of them independently .
But I need to have them function in automatic failover mode. I.e. once
the static route fails, the EIGRP-learned route should kick in without
manual intervention.
Right now, if there is a failure between Router C and Router X, the
EIGRP learned route to Router D's loopback does not kick in and so I
loose connectivity from Router A to Router D's loopback because the
static route is still in the routing table cause of its lower AD until
I manually intervene but I need the failover to be automated.
Which solutions can i use to achieve this automatic failover? I am
preparing for my CCIE lab.
Thanks
