Configuring Dynamic IPv6 BFD for IS-IS
Applicable Environment
If the requirement for data transmission is high and IS-IS convergence needs to be accelerated when the link status changes, you can configure dynamic BFD on IS-IS links. BFD can provide link failure detection featuring light load and high speed (at the millisecond level). With dynamic BFD, routing protocols can dynamically trigger the establishment of BFD sessions.
Dynamic BFD needs to be configured based on the actual network environment. If the time parameters are set improperly, network flapping may occur.
