Configuring BFD for BGP
BGP maintains neighbor relationships based on the keepalive timer and holdtime timer, which are set in
seconds. BGP defines that the holdtime interval must be at least three times the keepalive interval. This
mechanism makes link failure detection rather slow; once a failure occurs on a high-speed link, a large
quantity of packets will be dropped. BFD is introduced to solve this problem. It detects links between
neighbors quickly to reduce convergence time upon link failures.
To enable BFD for a BGP peer:

Command Remarks
1. Enter system view. system-view N/A
