IP Multicast FIB (mfib)
- 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.
