2018-03-09MPLS Unifom modeNeale Ranns1-81/+235
- support both pipe and uniform modes for all MPLS LSP - all API programming for output-labels requires that the mode (and associated data) is specificed - API changes in MPLS, BIER and IP are involved - new DPO [sub] types for MPLS labels to handle the two modes.

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.
