You can simple tune down EIGRP-metric for link r3-r6. (increase delay, not
BW). BTW under normal condition all packet will flow r1-r2-r5... If r2-r5
down EIGRP automaticaly recalculate path to r1-r3-r6.....
Once you want to use route-map you need to monitor reachabitie r6 and r5.
Try to use something like this
! define and start the rtrs
rtr 1
type echo protocol ipicmpecho 10.1.1.1
rtr schedule 1 start-time now life forever
!
rtr 2
type echo protocol ipicmpecho 10.2.2.2
rtr schedule 2 start-time now life forever
!
!track the rtrs
track 123 rtr 1 reachability
track 124 rtr 2 reachability
!
! enable policy routing on the incoming interface
interface ethernet 0
ip address 10.4.4.4 255.255.255.0
ip policy route-map alpha
!
! 10.1.1.1 is via this interface
interface ethernet 1
ip address 10.1.1.254 255.255.255.0
!
! 10.2.2.2 is via this interface
interface ethernet 2
ip address 10.2.2.254 255.255.255.0
!
! define a route-map to set the next-hop depending on the state of the tracked
rtrs
route-map alpha
set ip next-hop verify-availability 10.1.1.1 10 track 123
set ip next-hop verify-availability 10.2.2.2 20 track 124
