Interaction With Other Features
This section contains important information about MPLS interaction with other OmniSwitch features. 
Refer to the specific chapter for each feature to get more detailed information about how to configure and 
use the feature.
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.
Virtual Private LAN Service (VPLS)
The LDP-based MPLS implementation described in this chapter provides the core MPLS network required 
to provision Virtual Private Network (VPN) services. VPLS is the only such VPN supported to run over 
the OmniSwitch MPLS network at this time. See the “Configuring VPLS” chapter in the OmniSwitch AOS 
Release 6 Network Configuration Guide
 for more information.
VLAN Stacking (Ethernet Services)
Configuring MPLS functionality on VLAN Stacking ports or SVLANs is not supported.
