From 0f26c5a0138ac86d7ebd197c31a09d8d624c35fe Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Wed, 1 Mar 2017 15:12:11 -0800 Subject: 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.
