Multi-Service IronWare Switching Configuration Guide 293

Configuring PBB
11
VPLS-local-switching is turned on when PBB is configured. Since PBB support is internally
implemented using VPLS local switching, the local switching feature cannot be turned off when
PBB is configured for the given VPLS instance.
VC-mode configuration is not allowed under the PBB configuration.
ISIDs cannot be reused across VLANs under the PBB configuration.
Configuring PBB
Note that the configuration of PBB on the Brocade MLX series and Brocade NetIron XMR is done
under the VPLS CLI constructs, since PBB on the Brocade MLX series and Brocade NetIron XMR is
internally supported similar to Local VPLS. However, PBB on the Brocade MLX series and Brocade
NetIron XMR does not actually use MPLS. PBB on the Brocade MLX series and Brocade NetIron
XMR does not generate any MPLS signaling and does not use any MPLS protocols. All PBB traffic
conforms to the PBB standard.
PBB configuration is not enabled by default and must be enabled per VPLS instance. The optional
Backbone Destination MAC Address configuration under PBB is used for PBB connections, which
do not require flooding in the PBB core. The customer may use this capability to set the default
B-DA to the address of the destination BEB of the point-to-point connection.
Brocade(config)#router mpls
Brocade(config-mpls)#vpls-policy
Brocade(config-mpls-vpls-policy)#pbb
Brocade(config-mpls-vpls-policy-pbb)# b-dest-mac 2010.0345.4232
vlan 10
tagged ethe 4/1
vlan 200 isid 20000
tagged ethe 2/1
Enabling a new PBB configuration
The following command enables a PBB instance.
Brocade(config)#router mpls
Brocade(config-mpls)#vpls vinst 2000
Brocade(config-mpls-vpls-vinst)# pbb
Syntax: [no] pbb
PBB Backbone Destination MAC Address Configuration
Configuring a Backbone destination MAC address for a PBB instance allows the flood traffic to be
directed towards the specified BEB node instead of using the default backbone multicast
destination MAC address. This is used to create point-to-point connections (using a Unicast MAC
address).
Brocade(config)#router mpls
Brocade(config-mpls)#vpls vinst 2000
Brocade(config-mpls-vpls-vinst)# pbb
Brocade(config-mpls-vpls-vinst-pbb)#b-dest-mac 0001.0001.0003
Syntax: [no] b-dest-mac Ethernet MAC address used for point to point
A multicast MAC address will be allowed only if it has the well-known PBB MAC prefix of 01-1E-83.
The following MAC addresses are not allowed:
A broadcast MAC address is disallowed.
A zero MAC address is disallowed.
