RSTP support for PB and PBB

Use case 4: Edge RSTP - AS-1 is connected to AS-2 via IB-tagged endpoint and
both the AS on ES facing side with different S-VLAN
The following deployment scenario is a case where RSTP is deployed on a VPLS instance which has
a S-VLAN configured to the ES facing side and B-VLAN configured which connects 2 ASs.
AS-1 is configured as a ROOT Bridge. VPLS VLAN 200 is configured in AS-1 and AS-2 acts as B-VLAN
which connects AS-1 and AS-2. VPLS VLAN 300 is configured in AS-1 connects AS-1 to ES-1 and
VPLS VLSN 500 on AS-2 connects AS-2 to ES-1. In AS-1 VPLS VLAN 200 and 300 are configured
under same VPLS instance and AS-2 VPLS VLAN 200 and 500 are configured under the same VPLS
Instance. VPLS VLAN 300 (S-VLAN) configured on ES-1 which connects to AS-1 and VPLS VLAN 500
connects to AS-2.
The following discussion describes how to configure the nodes in the topology.

Configuring AS-1
Tag type configuration
Configure the port tag type for B-VLAN to 0x88a8.
Brocade_AS-1(config)#tag-type 88e8 eth 1/1
Configure port tag type for S-VLAN to 0x9100.
Brocade_AS-1(config)#tag-type 9100 eth 1/2
B-VLAN Configuration
Brocade_AS-1(config)#vlan 200
Brocade_AS-1(config-vlan-200)#tagged ethernet 1/1
