Route-replicate using Cisco EVN problem updating prefix-list within the route-map

Hi there, Currently we are testing Cisco's EVN solution.

I have two VRF's.

Within each VRF, I have an OSPF process running. Using the route-replicate command, including the route-map addition which calls an ACL within a prefix-list, I am able to successfully replicate routes in between the VRF's.

vrf definition VRF-1

address-family ipv4

route-replicate from vrf VRF-2 unicast ospf 2 route-map FROM_VRF-2_TO_VRF-1

exit-address-family

vrf defintion VRF-2

adress-family ipv4 route-replicate from vrf VRF-1 unicast ospf 1 route-map FROM_VRF-1_TO_VRF-2

exit-address-family

router ospf 1 vrf VRF-1 network x.x.x.x y.y.y.y area 0

router ospf 2 vrf VRF-2 network x.x.x.x y.y.y.y area 1

ip prefix-list FROM_VRF-1_TO_VRF-2 seq 5 permit 100.100.100.0/24

ip prefix-list FROM_VRF-2_TO_VRF-1 seq 5 permit 100.100.100.0/24

ip prefix-list FROM_VRF-2_TO_VRF-1 seq 10 permit 40.40.40.0/24

route-map FROM_VRF-1_TO_VRF-2 permit 10

   match ip address prefix-list FROM FROM_VRF-1_TO_VRF-2

ip prefix-list FROM_VRF-2_TO_VRF-1 permit 10

   match ip address prefix-list FROM FROM_VRF-2_TO_VRF-1

Although after expanding the prefix-list (route 40.40.40.0/24), used within the route-map statement, the specific route isn't automatically replicated within the other VRF"s RIB.

Only after manually clearing both OSPF processes ("clear ip ospf process"), the new route is added to the neighbour's VRF.

I have waited for 1800 seconds before clearing the process, but that didn't help either.

Shouldn't their be a way this new route 40.40.40.0/24 gets replicated automatically?

kind regards Dion Dohmen

Hi,

Per my understanding this is expected. VRF leaked route might require a route/process clear to get any modified policies.
