Configuring CE-1
C-VLAN Configuration
Configure a regular Layer 2 VLAN with 400 (C-VLAN) and add port 1/1 to it.
Brocade_CE-1(config)#vlan 400
Brocade_CE-1(config-vlan-400)#tagged ethernet 1/1
Configuring CE-2
C-VLAN Configuration
Configure a regular Layer 2 VLAN with 400 (C-VLAN) and add port 1/4 to it.
Brocade_CE-2(config)#vlan 400
Brocade_CE-2(config-vlan-400)#tagged ethernet 1/4
Configuring RSTP on CE-1 and CE-2

Use case 6: Core RSTP
The following deployment scenario is a case where RSTP is deployed for a single B-VLAN in a PBB
network. In CS-1 and CS-2 a regular VLAN 100 is configured as B-VLAN which carries the traffic to
the PBB core network. AS-1 and AS-2 have a regular VLAN and VPLS VLAN 100 which carries PBB
traffic towards the B-VLAN. CS-1 is configured as the ROOT Bridge and RSTP is running over regular
VLAN 100 in CS-1 and CS-2. In AS-1 and AS-2 RSTP runs over the regular VLAN 100 corresponds to
the VPLS VLAN B-VLAN 100.
The following discussion describes how to configure the nodes in the topology.
