2018-03-20FIB Interpose SourceNeale Ranns1-203/+214
The interpose source allows the source/provider to insert/interpose a DPO in the forwarding chain of the FIB entry ahead of the forwarding provided by the next best source. For example if the API source (i.e the 'control plane') has provided an adjacency for forwarding, then an interpose source (e.g. a monitoring service) couold interpose a replicatte DPO to copy the traffic to another location AND forward using the API's adjacency. To use the interose feature an existing source (i.e FIB_SOURCE_PLUGIN_HI) cn specifiy as a flag FIB_ENTRY_FLAG_INTERPOSE and provide a DPO to interpose. One might also consider using interpose in conjunction with FIB_ENTRY_FLAG_COVER_INHERIT to ensure the interpose object affects all prefixes in the sub-tree.

2018-03-09MPLS Unifom modeNeale Ranns1-2/+4
- 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.

2017-09-11FIB table add/delete APINeale Ranns1-4/+7
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-08-08L2 over MPLSNeale Ranns1-7/+7
[support for VPWS/VPLS] - switch to using dpo_proto_t rather than fib_protocol_t in fib_paths so that we can describe L2 paths - VLIB nodes to handle pop/push of MPLS labels to L2 Change-Id: Id050d06a11fd2c9c1c81ce5a0654e6c5ae6afa6e Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-04-07MPLS McastNeale Ranns1-2/+125
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.

2017-02-02Fix SR multicast post mfib commitNeale Ranns1-2/+54
1 - use the SR policy to construct the replicate DPO. Each bucket therein is a SR tunnel. 2 - install a special mfib entry that links via this replicate 3 - forwarding is now mfib-lookup -> replicate -> sr_rewrite (per-tunnel) no need for a separate sr_replicate node. 4 - Stack the sr tunnel on the forwarding DPO of the first-hop FIB entry. no need for a second lookup post SR encap. 5 - fix some path-list lock leaks in the MFIB entry.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+1225
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
