Configuring MPLS VPNs
Layer 3 VPNs allow you to establish VPNs in a routed environment, improving the flexibility and ease
of maintenance of VPNs. For instructions on how to configure layer 3 VPNs, see the
MPLS Configuration Guide, Cisco IOS Release 15.1S.
The following restrictions apply to MPLS VPNs:
When the port channel is on core, bridge ID must be equal to the encapsulation ID.
Equal Cost Multipath (ECMP) is not supported for swap cases.
