The table lists the RSVP Provider-Network Multicast Service (PMSI)
interfaces.
A PMSI can be thought of as a connector between a set of PE routers
forming a Multicast Domain. From the perspective of a VPN-specific
PIM instance, a PMSI is a single multi-access interface.
A PMSI interface is created whenever the threshold of a C-(S,G)
exceeds the configured threshold value specified by vRtrPimNgDataMtThd.
If the data-threshold goes below the value specified by
vRtrPimNgDataMtThd, the PMSI interface is automatically deleted.
