interval. This mechanism makes the detection of a link failure rather slow and thus causes a large
quantity of packets to be dropped especially when the failed link is a high-speed link. You can enable
BFD to detect the link to a peer. BFD can quickly detect any link failure and thus reduce network
convergence time.
Before you configure BFD for IPv6 BGP, you must enable BGP.
For more information about BFD, see High Availability Configuration Guide.
