2019-12-04fib: Decouple source from priority and behaviourNeale Ranns1-2/+3
Type: feature the fib_source_t enum alone no longer defines the priority and behaviour, instead each source must be allocated these attributes. This allows the creation of other sources by the plugins (and soon over the API). Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I890ee820fbc16079ee417ea1fbc163192806e853
2018-03-20FIB Interpose SourceNeale Ranns1-2/+2
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.

2017-08-08L2 over MPLSNeale Ranns1-4/+4
[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>
