Configuring a PBR policy

The no set next-hop-flood-vlan vlan-id outgoing-da mac-address command deletes only the

outgoing-da option from the set statement. It does not delete the set statement itself. To delete the

set statement, the user would have to specify the no set next-hop-flood-vlan vlan-id command.

In the case of traffic incoming on MPLS uplink, PBR to VLAN flooding is only supported for IPv4

traffic, and not for MPLS traffic.

Enabling PBR

After you configure the ACLs and route map entries, you can enable PBR globally, on individual

interfaces, or both as described in this section. To enable PBR, you apply a route map you have

configured for PBR globally or locally.

Enabling PBR globally

To enable PBR globally, enter a command such as the following at the global CONFIG level.

Brocade(config)# ip policy route-map test-route

This command applies a route map named “test-route” to all interfaces on the device for PBR.

Syntax: [no] ip policy route-map map-name

Enabling PBR locally

To enable PBR locally, enter commands such as the following.

Brocade(config)# interface ve 1

Brocade(config-vif-1)# ip policy route-map test-route

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: [no] ip policy route-map map-name

Enter the name of the route map you want to use for the route-map map-name parameter.

Support for Switched Traffic Not Supported Supported

If the outgoing-da option is not set Packet floods with original SA/DA Switched traffic:

Packet floods with original SA/DA.

Routed traffic (L3 CAM miss):

Packet floods with original SA/DA.

Routed traffic (L3 CAM hit):

Packet floods with original SA and DA

as next-hop MAC.

If the outgoing-da option is set DA: Configured outgoing-da

SA: Outgoing port MAC

DA: Configured outgoing-da

SA: Original SA

VLANID is configured but no ports

are added or all ports are down

Go to next set statement. Drop matching packets.
