BFD的2种模式区别与相应的使⽤场景
what is BFD
Summary
Bidirectional Forwarding Detection (BFD) is a low-overhead and short-duration protocol intended to detect faults in the bidirectional path between two forwarding engines, including physical interfaces, sub-interfaces, data link(s), and to the extent possible the forwarding engines themlves, with potentially very low latency. It operates independently of media, data protocols and routing protocols.
BFD is basically a hello protocol for checking bidirectional neighbor reachability. It provides sub-cond link failure detection support. BFD is not routing protocol specific, unlike protocol hello timers or such.
BFD Control packets is transmitted in UDP packets with destination port 3784, BFD also us port 4784 for multihop paths. Source port is in the range 49152 through 65535. And BFD Echo packets are encapsulated in UDP packet with destination port 3785.钱币石
