Policy-based routing (PBR)
The commands in this example change the CLI to the Interface level for virtual interface 1, then
apply the "test-route" route map to the interface. You can apply a PBR route map to Ethernet ports
or virtual interfaces.
Syntax: ip policy route-map <map-name>
Enter the name of the route map you want to use for the route-map <map-name> parameter.
Configuration examples
This section presents configuration examples for configuring and applying a PBR policy.

Basic example

The following commands configure and apply a PBR policy that routes HTTP traffic received on
virtual routing interface 1 from the 10.10.10.x/24 network to 5.5.5.x/24 through next-hop IP
address 1.1.1.1/24 or, if 1.1.1.x is unavailable, through 2.2.2.1/24.
PowerConnect(config)#access-list 101 permit tcp 10.10.10.0 0.0.0.255 eq http
5.5.5.0 0.0.0.255
PowerConnect(config)#route-map net10web permit 101
PowerConnect(config-routemap net10web)#match ip address 101
PowerConnect(config-routemap net10web)#set ip next-hop 1.1.1.1
PowerConnect(config-routemap net10web)#set ip next-hop 2.2.2.2
PowerConnect(config-routemap net10web)#exit
PowerConnect(config)#vlan 10
PowerConnect(config-vlan-10)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-10)#router-interface ve 1
PowerConnect(config)#interface ve 1
PowerConnect(config-vif-1)#ip policy route-map net10web
Syntax: [no] route-map <map-name> permit | deny <num>
Syntax: [no] set ip next hop <ip-addr>
This command sets the next-hop IP address for traffic that matches a match statement in the route
map.
Setting the next hop
The following commands configure the Brocade 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:
•
•
•
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 Brocade 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.
588
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.
