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 nexthop 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. Use PBR to permit and block specific traffic This section explains how to permit specific traffic through an interface using PBR. Configure the interface 1. Create a VLAN interface. OS10(Config)# interface vlan999 2. Enable the interface. OS10(Conf-if-999)# no shutdown 3. Enter an IP address to the interface. OS10(Conf-if-999)# ip address 10.99.0.251/16 Define the PBR parameters • Create an ACL and define what should be enabled for PBR processing. ip access-list TEST-ACL seq 10 permit tcp any any eq 80 seq 20 permit tcp any any eq 443 seq 30 permit tcp any any eq 21 seq 40 permit icmp any any • Create an ACL and define what should be excluded from PBR processing. ip access-list TEST-ACL-DENY seq 10 permit tcp 10.99.0.0/16 10.0.0.0/8 eq 80 seq 20 permit tcp 10.99.0.0/16 10.0.0.0/8 eq 443 seq 30 permit tcp 10.99.0.0/16 10.0.0.0/8 eq 21 seq 40 permit icmp 10.99.0.0/16 10.0.0.0/8 • Create a route-map to block specific traffic from PBR processing. route-map TEST-RM deny 5 match ip address TEST-ACL-DENY 730 Layer 3
