• Traffic received from any port in the LAG is forwarded to the VPLS instance. All traffic is
matched to its VLAN.
Support for VPLS endpoints within a Topology group
The user can configure VPLS VLANs into Topology groups so that the user can use any of the
following protocols within a VPLS VLAN:
• Spanning Tree Protocol (STP)
• Rapid Spanning Tree Protocol (RSTP)
• Foundry Metro Ring Protocol (MRP)
• Virtual Switch Redundancy Protocol (VSRP)
Flooding Layer 2 BPDUs in VPLS
By default, Layer 2 STP and Per VLAN Spanning Tree (PVST) Bridge Protocol Data Units (BPDUs)
entering a VPLS endpoint are not transparently flooded within the VPLS instance. The BPDUs are
dropped when they enter the VPLS endpoint. The user can change this default behavior to not
block BPDUs and transparently flood them within the VPLS instance, by configuration on a
per-physical-port basis. Because the BPDU block option is configurable per physical interface, it
affects all VPLS instances that have endpoints on that interface.
To flood BPDUs in VPLS, use the following command.
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e10000-1/1)# no vpls-bpdu-block
Syntax: [no] vpls-bpdu-block
Specifying the VPLS VC type
NOTE
This is a global setting that affects all VPLS instances, except those in VPLS tagged mode. The user
must save the configuration and reload the software to place the change into effect.
The default VC type for all VPLS instances is set to 0x5 or “Ethernet”. For compatibility with
previous versions, the VC type can be changed to 0xB or “Ethernet VPLS”. The VC type must match
between peers for the VPLS session to be established.
NOTE
When VPLS tagged mode is enabled for a VPLS instance, the VC type for that instance is set to 0x04
or “Ethernet Tagged”, regardless of the global VPLS VC type setting.
To change the VPLS VC type, use the following command at the MPLS configuration level.
Brocade(config-mpls)# vpls-vc-type-ethernet-vpls
VPLS VC type is 0xB (Ethernet VPLS) after the user saves to config and reboot.
Syntax: [no] vpls-vc-type-ethernet-vpls
