Question 21

Which of the following statements about the operation of seamless-BFD is FALSE?

Seamless-BFD responses are sent back using the LSP label stack.

To be able to respond to seamless-BFD messages, a router must be configured as a reflector.

A seamless-BFD template needs to be configured on the head-end of the LSP.

The routing protocol (OSPF or IS-IS) is used to carry the reflector discriminator information.

Correct Answer: A

Seamless-BFD responses are sent back using the shortest path determined by the IGP (Interior Gateway Protocol) rather than the LSP (Label Switched Path) label stack. This would make the statement 'Seamless-BFD responses are sent back using the LSP label stack' incorrect.
