A. The interface connected to the MPLS domain must use one of the Optical Services Modules (OSM) (for example, any module that utilizes Parallel Express Forwarding (PXF) complex) or an interface in the FlexWAN module. The same restriction exists for MPLS Layer 3 VPN. That is, the IP frame must enter on a WAN interface which is either an OSM or an interface in a FlexWAN module. These restrictions do not exist on a Supervisor 720.
