MPLS

The 7705 SAR-Hm series of routers support MPLS as described in Label Distribution Protocol.

T-LDP is required for VPLS and Epipe services that depend on T-LDP signaling for label distribution and control. See the Layer 2 and Layer 3 services chapter for more information about services supported on the 7705 SAR-Hm series.
