RSTP support for PB and PBB

Use case 2: Edge RSTP - AS-1 is connected to AS-2 and ES-1 via S-tagged
endpoints of different S-VLAN
The following deployment scenario is a case where RSTP is deployed on two different S-VLANs of
the same VPLS instance in a PB network. Here AS-1 is configured as a ROOT Bridge and RSTP is
running on the VPLS Instance on AS-1, AS-2, and ES-1. VPLS VLAN 200 configured on AS-1 and
AS-2 acts as an S-VLAN which connects AS-1 and AS-2. VPLS VLAN 300 configured on AS-1 and
AS-2 acts as another S-VLAN which connects AS-1 and AS-2 to the ES-1. AS-1 and AS-2 has the
VPLS VLAN 200 and 300 configured under same VPLS instance. VPLS VLAN 300 (S-VLAN) is
configured ES-1 connects to AS-1 and AS-2.
The following discussion describes procedure required to configure the nodes in the topology.

Configuring AS-1
Tag type configuration
Configure 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
