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> Signed-off-by: Radhika Mahankali <radhika@cumulusnetworks.com> Reviewed-by: Dinesh G Dutt <ddutt@cumulusnetworks.com> Reviewed-by: Vipin Kumar <vipin@cumulusnetworks.com> Reviewed-by: Kanna Rajagopal <kanna@cumulusnetworks.com>
