as decsribed in section 2.2 ihttps://tools.ietf.org/html/draft-ietf-bier-mpls-encapsulation-10 with BIFT encoding from: https://tools.ietf.org/html/draft-wijnandsxu-bier-non-mpls-bift-encoding-00 changes: 1 - introduce the new BIFT lookup table. BIER tables that have an associated MPLS label are added to the MPLS-FIB. Those that don't are added to the BIER table 2 - BIER routes that have no associated output MPLS label will add a BIFT label. 3 - The BIER FMask has a path-list as a member to resolve via any possible path.

2017-11-26FIB: optimise for src memory allocationsNeale Ranns5-121/+264
Most FIB entries will only ever have one source providing forwarding information. Currently the source infom is stored in a vector of sources on the FIB entry. Change this to a union of one source inline and a vector. This saves the need to alloc a vector of sources for each FIB entry. before: vpp# ip route add count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 4.392857e5 routes/sec vpp# ip route del count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 9.175464e5 routes/sec vpp# ip route add count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 5.193375e5 routes/sec vpp# sh fib mem FIB memory Name Size in-use /allocated totals Entry 72 1500011/ 1500011 108000792/108000792 Entry Source 32 1500011/ 1500011 48000352/48000352 after: vpp# ip route add count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 4.726560e5 routes/sec vpp# ip route del count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 1.041629e6 routes/sec vpp# ip route add count 1500000 1.0.0.1/32 via 10.10.10.2 loop0 5.702895e5 routes/sec vpp# sh fib mem FIB memory Name Size in-use /allocated totals Entry 96 1500011/ 1500011 144001056/144001056 Entry Source 32 0 / 0 0/0 Change-Id: Ic71e413eaff1ec152656beda3b94186f7894ea49 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-10-05Distributed Virtual Router SupportNeale Ranns5-100/+100
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

2017-08-21PPPoE usses a midchain adjacency stack on an interface-tx DPONeale Ranns2-14/+14
1) introduce an interface-tx DPO. This is a simple wrapper around a sw_if_index. enhance DPO stacking functions to allow per-instance next-nodes and hence allow children to stack onto the interface per-instance tx node and not on 'interface-output'. 2) update PPPoE code to use ta midchain stack on a interface-tx DPO of the encap-interface. This remove the need for pppoe_encap node (which is replaced by the adj-midchain-tx) and interface-output node is no longer used (see above). Since PPPoE encap node is no longer needed, the PPPoE seesion does not need to be retrieved in the data-path, hence the cahce misses are removed.

2017-05-23ARP/ND entries for the same address on different interfaces (VPP-848)Neale Ranns13-621/+1159
there are, intentionally, no validation checks in the ARP/ND code to prevent an ARP/ND entry from being installed for an address that is not local to the interface's sub-net. This is ok, since the adjacency/FIB code is designed to handle this case using the 'refinement' criteria - i.e. only installing a FIB entry for the address if the address 'refines' (i.e. is more specific than) the interface's sub-net. However, the refinement criteria currently operates on the FIB entry's prefix (which is a /32, so on the address) and not on the next-hop in the path. So, enter multiple ARP entries for the same address on different links, and this refinement criteria uses only the last added path, and so will remove the FIB entry should the ARP entries be added in the 'wrong' order. This fix updates the refinement criteria to work on each path of the FIB entry. The entry is installed if one of the paths refines the covers and only paths refining the cover contribute forwarding. Per-path refinement checks are stored in path-extensions. The patch is rather large as path-extension, which were previously used only for out-going MPLS labels, have been generalized.
