Paths with leading * are configured but disabled, entries with + is for IPv6

Route-map ACL Output Output

Rule Name Input Policy Match VLAN Port(s)

*test-traffic N/A Testing TestACL N/A N/A

*xGW_path1 N/A other_map xGW_Filter2 N/A N/A

xGW_path1 10/1 10/2 xGW_map xGW_Filter1 2 N/A

xGW_path1 +10/1 xGW_map xGW_Filter1 2 N/A

xGW_path2 10/1 10/2 xGW_map xGW_Filter2 None 4/1

xGW_path2 +10/1 xGW_map None 4/1

Policy-based routing support for preserve VLAN

NOTE

Policy-based routing support for preserve VLAN is supported only on Brocade NetIron XMR and
Brocade MLX Series routers. This feature is now supported on the BR-MLX-10GX24 module.

Previously, PBR transparent VLAN flooding (TVF) replaced the ingress traffic’s VLAN ID with the
egress TVF VLAN ID, while flooding the egress TVF VLAN. Policy-based routing support for preserve
VLAN allows the ingress packet VLAN header (VLAN ID and priority) to be preserved, while
simultaneously flooding the PBR TVF VLAN.
