IOS XR and Policy Based Routing

[n]

I have the following configured on IOS-XE, I want to accomplish the same thing on IOS XR

access-list 1 deny   tcp any eq www 192.168.1.0 0.0.0.255
access-list 1 permit tcp any eq www any

route-map Test permit 10
 match ip address 1
 set ip next-hop 192.168.2.1
 set ip next-hop verify-availability
!

I understand that in IOS XR I have to use ABF to accomplish this.

Can I create the ABF and reference it in a Route Policy or do I Apply the ABF directly to an interface?

Thanks

Hi,

You can try below ACL

ipv4 access-list ABF_IGW

10 deny tcp any eq www 192.168.1.0/24

20 permit tcp any eq www any nexthop1 track IGW ipv4 192.168.2.1

!

Configure IP SLA and Tracking

ipsla

operation 1

type icmp echo

   destination address 192.168.2.1

   frequency 5

schedule operation 1

start-time now

life forever

!

track IGW

type rtr 1 reachability

!
