Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Track route reachability

1. Configure object tracking.
   track track-id

      OS10(config)# track 200

2. Configure reachability of the next-hop address through the VRF instance.
   ip ip-address reachablility vrf vrf-name

      OS10(conf-track-200)#
      OS10(conf-track-200)# ip 1.1.1.1 reachability vrf red
      OS10(conf-track-200)#exit

3. Configure the route-map.
   route-map route-map-name

      OS10(config-route-map)#
      OS10(config-route-map)# match ip address acl1

4. Set the track ID configured in step 1 to the route-map.
   set ip vrf vrf-name nexy-hop next-hop-address track-id track-id-number

    OS10(config-route-map)# set ip vrf red next-hop 1.1.1.1 track-id 200

5. Apply the route-map to the interface where traffic is ingressing on the VRF instance.
   interface interface-type
   ip policy route-map route-map-name

      OS10(config)# interface vlan 40
      OS10(conf-if-vl-40)#
      OS10(conf-if-vl-40)# ip policy route-map test
      OS10(conf-if-vl-40)# show configuration
      !

   NOTE Ensure you configure next-hop IP address tracking and PBR next-hop with the same VRF instance. For next-hop reachability in the same VRF instance, you must configure both PBR per VRF and object tracking. Missing either the next-hop IP address tracking or PBR next-hop configuration in a VRF instance results in an erroneous configuration. However, the system does not display an error message indicating problems in the configuration.
