1.
Create an extended ACL 155 to match packets with destination IP address in the 11.0.0.0/8 or 14.0.0.0/8 subnets and
the precedence value set as routine:
configure access-list 155 permit ip any 11.0.0.0 0.255.255.255 precedence routine
configure access-list 155 permit ip any 14.0.0.0 0.255.255.255 precedence routine
2.
Configure route map named testroutemap and sequence number 10 to match ACL 155:
configure route-map-policy testroutemap permit 10 match ip address 155
3.
Set the next hop address to 67.59.234.169:
configure route-map-policy testroutemap permit 10 set ip next-hop 67.59.234.169
4.
Apply the route map named testroutemap to interface cable-mac 1:
configure interface cable-mac 1 ip policy route-map-policy testroutemap
5.
Run the following show commands to confirm your configuration:
show access-list
show ip interface cable-mac 1
show route-map-policy
show ip policy
PBR Script Setup – IP Next-Hop
The following script is offered as an example of an implementation of PBR. PBR can be applied to one or more C4/c CMTS
interfaces. The two chosen in the following procedure are meant as examples.
1.
Create standard access lists 20, 30 & 40:
configure access-list 20 permit 10.10.20.0 0.0.0.255
configure access-list 30 permit 10.10.30.0 0.0.0.255
configure access-list 40 permit 10.10.40.0 0.0.0.255
2.
Configure route map named routemap1 and sequence number 10 to match ACL 20; set the next-hop to 10.69.1.1; and
set the backup next-hop to 10.69.2.1:
configure route-map-policy routemap1 permit 10 match ip address 20
configure route-map-policy routemap1 permit 10 set ip next-hop 10.69.1.1
configure route-map-policy routemap1 permit 10 set ip backup-next-hop 10.69.2.1
3.
Configure routemap1, sequence number 20, to match ACL 30; set the next-hop to 10.69.3.1; and set the backup next-
hop to 10.69.4.1; and set the ToS to normal:
configure route-map-policy routemap1 permit 20 match ip address 30
configure route-map-policy routemap1 permit 20 set ip next-hop 10.69.3.1
configure route-map-policy routemap1 permit 20 set ip backup-next-hop 10.69.4.1
configure route-map-policy routemap1 permit 20 set ip tos normal
4.
Configure routemap1, sequence number 30, to drop all packets:
