Hi Loval, I skimmed through the RFC 7882 and it shouldn't be too much trouble adding that functionality to VPP. The existing BFD code is still a work in progress and the only reason it's been pushed to the git was the API freeze, so please do expect more patches to be pushed and things could change.
Currently, there is no CLI, only API access, which is partially implemented. The global configuration APIs are not implemented yet, only per-session ones: bfd_udp_add, bfd_udp_del, bfd_udp_session_dump. I suggest you take a look at test/test_bfd.py, which contains the unit tests for the BFD feature. Again, this is not complete and more tests will follow. To run the tests, you can do e.g. make test-debug TEST=bfd V=2 (adjust test verbosity V= to your liking, 2 is most verbose, 0 least) The VPP BFD code is roughly split into BFDs-specific functionality and transport-specific functionality - that being UDP only at this time, while thinking about e.g. MPLS in the future.
