Configuring Bfd For Ipv6 Is-Is - HPE FlexNetwork HSR6800 Configuration Manual

Configuring BFD for IPv6 IS-IS

Network requirements
As shown in
BFD over the link Router A<—>L2 Switch<—>Router B.
When the link between Router B and the Layer-2 switch fails, BFD can quickly detect the failure and
notify IPv6 IS-IS of the failure. Then Router A and Router B communicate through Router C.
