Point to Point PBB
Point to Point PBB (P2P PBB) provides the ability to turn off MAC address learning on a per service
instance basis (ISID). This provides support for point-to-point services, such as EVPL, which do not
require MAC address learning. Point to Point PBB is designed to flood the traffic to a specific
remote BEB in the core PBB network, instead of flooding across all the BEBs.
Limitations
When P2P PBB is enabled, the MACs learned on S-VLANs are duplicated in the new flood domain.
This will reduce the maximum number of supported MACs from 131072 VPLS MACs to 65536 VPLS
MACs.
Configuring Point to Point PBB
Use the p2p-mac command to enable this feature. Since the P2P PBB feature is specific to a
service instance it has to be executed for each ISID.
Brocade(config)#esi A-isid encapsulation isid
Brocade(config-esi-A-isid)#isid 18001
Brocade(config-esi-A-isid-isid-18001)#p2p-mac 001b.edb4.5ac1
Syntax: [no] p2p-mac mac-addr
The mac-addr parameter requires the MAC address of the remote BEB.
Use the [no] parameter to disable this feature.
Show commands
Use the show flood-domain command to display the extra flood-domain (shadow flood domain).
This extra flood domain information is only shown for P2P PBB instances.
Brocade# show flood-domain

You can use the show flood-domain fd_id to filter the flood domain. The show flood-domain
shadow_fd_id command can also be used to show the identical information.
