2018-12-07FIB recusrion loop checks traverse midchain adjacenciesNeale Ranns1-2/+14
if a tunnel's destination address is reachable through the tunnel (see example config belwo) then search for and detect a recursion loop and don't stack the adjacency. Otherwise this results in a nasty surprise.

2018-03-20FIB Interpose SourceNeale Ranns18-3987/+5041
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.
