Usage guidelines
For quicker RIPng FRR, use BFD single-hop echo detection on the primary link of redundant links to
detect link failure.
For correct operation of BFD, make sure the interface is configured with an IPv6 global unicast
address before you execute this command. For more information about IPv6 global unicast
addresses, see IPv6 basics configuration in Layer 3—IP Services Configuration Guide.
