Setting the next hop
The following commands configure the device to apply PBR to traffic from IP subnets 209.157.23.x,
209.157.24.x, and 209.157.25.x. In this example, route maps specify the next-hop gateway for
packets from each of these subnets:
• Packets from 209.157.23.x are sent to 192.168.2.1.
• Packets from 209.157.24.x are sent to 192.168.2.2.
• Packets from 209.157.25.x are sent to 192.168.2.3.
The following commands configure three standard ACLs. Each ACL contains one of the ACLs listed
above. Make sure you specify permit instead of deny in the ACLs, so that the device permits the
traffic that matches the ACLs to be further evaluated by the route map. If you specify deny, the
traffic that matches the deny statements are routed normally. Notice that these ACLs specify any
for the destination address.
BigIron RX(config)# access-list 50 permit 209.157.23.0 0.0.0.255
BigIron RX(config)# access-list 51 permit 209.157.24.0 0.0.0.255
BigIron RX(config)# access-list 52 permit 209.157.25.0 0.0.0.255
The following commands configure three entries in a route map called “test-route”. The first entry
(permit 50) matches on the IP address information in ACL 50 above. For IP traffic from subnet
209.157.23.0/24, this route map entry sets the next-hop IP address to 192.168.2.1.
BigIron RX(config)# route-map test-route permit 50
BigIron RX(config-routemap test-route)# match ip address 50
BigIron RX(config-routemap test-route)# set ip next-hop 192.168.2.1
BigIron RX(config-routemap test-route)# exit
The following commands configure the second entry in the route map. This entry (permit 51)
matches on the IP address information in ACL 51 above. For IP traffic from subnet
209.157.24.0/24, this route map entry sets the next-hop IP address to 192.168.2.2.
BigIron RX(config)# route-map test-route permit 51
BigIron RX(config-routemap test-route)# match ip address 51
BigIron RX(config-routemap test-route)# set ip next-hop 192.168.2.2
BigIron RX(config-routemap test-route)# exit
The following commands configure the third entry in the test-route route map. This entry (permit
52) matches on the IP address information in ACL 52 above. For IP traffic from subnet
209.157.25.0/24, this route map entry sets the next-hop IP address to 192.168.2.3.
BigIron RX(config)# route-map test-route permit 52
BigIron RX(config-routemap test-route)# match ip address 52
BigIron RX(config-routemap test-route)# set ip next-hop 192.168.2.3
BigIron RX(config-routemap test-route)# exit
The following command enables PBR by globally applying the test-route route map to all interfaces.
BigIron RX(config)# ip policy route-map test-route
Alternatively, you can enable PBR on specific interfaces, as shown in the following example. The
commands in this example configure IP addresses in the three source subnets identified in ACLs
50, 51, and 52, then apply route map test-route the interface.
BigIron RX(config)# interface ve 1
BigIron RX(config-vif-1)# ip address 209.157.23.1/24
BigIron RX(config-vif-1)# ip address 209.157.24.1/24
BigIron RX(config-vif-1)# ip address 209.157.25.1/24
BigIron RX(config-vif-1)# ip policy route-map test-route
