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
In set next-hop-flood-vlan, if the
VLANID is configured but no ports
are added or all ports are down Go to next set statement. Drop matching packets.
