Donald Sharp c43ed2e48a This patch changes BGP from only listening mode for BFD status updates to interactive mode of dynamically registering/deregistering BFD enabled peers with PTM/BFD through zebra. Peer is registered with BFD when it goes into established state and de-registers when it goes out of establish state.
This patch also adds BFD multihop support for BGP. Whether a peer is multi-hop or single hop is determined internally. All IGP peers are considered as multi-hop peers. EBGP peers are considered as single hop unless configured as multi-hop.

BGP BFD command enhancement to configure BFD parameters (detect multiplier, min rx and min tx).

router bgp <as-number>
  neighbor <name/ip-address> bfd <detect mult> <min rx> <min tx>
