[RouterA] route-policy lab1 permit node 20
[RouterA-route-policy] if-match packet-length 101 1000
[Router-route-policy] apply ip-address next-hop 151.1.1.2
# Configure Router B:
[RouterB] interface serial 1/0/0
[RouterB-Serial1/0/0] ip address 150.1.1.2 255.255.255.0
[RouterB] interface serial 1/0/1
[RouterB-Serial1/0/1] ip address 151.1.1.2 255.255.255.0
[RouterB] rip

[RouterB-rip] network 151.1.0.0
Use the debugging ip policy command to monitor policy routing on Router A. Note:
the packets of 64 bytes long match the entry item whose id number is 10 as shown in
the route policy lab1, therefore they are forwarded to 150.1.1.2.
<RouterA> debugging ip policy
*0.483448-POLICY-8-POLICY-ROUTING:IP Policy routing success : next-hop :
150.1.1.2
On Router A, change the packet size to 101 bytes and monitor policy routing with the
debugging ip policy command. Note: the packets of 101 bytes match the entry item
whose serial number is 20 as shown in the route policy lab1. They are forwarded to
151.1.1.2.
<RouterA> debugging ip policy
*0.483448-POLICY-8-POLICY-ROUTING:IP Policy routing success : next-hop :
151.1.1.2
On Router A, change the packet size to 1001 bytes, and then use the debugging ip
policy command to monitor policy routing. Note that this packet does not match any
entry item in lab1, so it is forwarded in regular mode. The policy routing debugging does
not output information of the forwarding packets.
