VOSS ISIS-OSPF Lab 2 (Reject Policy)

It is possible for the cluster routers to advertise an ISIS route into OSPF and overwrite the ISIS learnt routes on the peer router. To avoid this from occurring use a route map to reject routes from the peer OSPF router-ID.

R1 and R2:

route-map “reject” 1
no permit
enable
exit

R1:

router ospf
accept adv-rtr 10.255.0.2 enable route-map “reject”
exit

ip ospf apply accept adv-rtr 10.255.0.2

R2:

router ospf
accept adv-rtr 10.255.0.1 enable route-map “reject”
exit

ip ospf apply accept adv-rtr 10.255.0.1
