Multiple Virtual Routing and Forwarding (VRF)

Virtual Private LAN Service (VPLS) tunnels and the Label Distribution Protocol (LDP) associate with the
default VRF instance. These MPLS components are not supported in any other VRF instance.

VLAN Management

•
This implementation of VPLS provides a bridging domain that is separate from the VLAN bridging
domain. Although both may exist on the same switch, once ports/VLANs are configured for use with
one of these domains, these entities are no longer configurable for the other domain.
•
When a port is configured as a VPLS access port, the default VLAN for the port is reserved for VPLS
use and is no longer configurable using VLAN management commands.

VLAN Stacking

•
VLAN Stacking services are not configurable on VPLS access and network ports, but are allowed on
the same switch.
•
Prior to configuring MPLS/VPLS for the switch, identify and configure VLAN Stacking user and
network ports.
•
IP interfaces are configurable on VPLS network ports but are not allowed on VLAN Stacking network
ports. This ensures that the VLAN Stacking network is kept separate from the MPLS/VPLS network.
•
If a customer frame received on an access port is double tagged, only the outer tag is used to classify
the packet into a VPLS service.
•
This implementation of VPLS requires the configuration of Service Access Points (SAPs) to identify
