RSTP support for PB and PBB

Use case scenarios
Use case 1: Edge RSTP - AS-1 is connected to AS-2 and ES-1 via S-tagged
endpoints of same S-VLAN
The following deployment scenario is a case where RSTP is deployed for a single S-VLAN in a PB
network. VPLS VLAN 200 (S-VLAN) is responsible for carrying traffic to the PB network. In this case,
AS-1 is configured as ROOT Bridge, VPLS VLAN 200 is configured on AS-1, AS-2, and ES-1 which
connects the three bridges together. RSTP is running on the VPLS Instance on AS-1, AS-2 and ES-1.
The following describes the steps to configure the nodes in the topology.

Configuring AS-1
Tag type configuration
Configure the port tag type for S-VLAN to 0x9100.
Brocade_AS-1(config)#tag-type 9100 eth 1/1
Brocade_AS-1(config)#tag-type 9100 eth 1/2
S-VLAN Configuration
Configure VPLS VLANs which will carry the PB traffic, the S-VLAN here is 200.
Brocade_AS-1(config)#router mpls
Brocade_AS-1(config-mpls)#vpls pb-svlan 1
Brocade_AS-1(config-mpls-vpls-pb-svlan)#pbb
