MPLS Mcast
1 - interface-DPO
Used in the Data-plane to change a packet's input interface
2 - MPLS multicast FIB entry
Same as a unicast entry but it links to a replicate not a load-balance DPO
3 - Multicast MPLS tunnel
Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to .
4 - Resolve a path via a local label (of an mLDP LSP)
For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP.
5 - MPLS disposition path sets RPF-ID
For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet.
6 - RPF check with per-entry RPF-ID
An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.
