QuestionQ2

Multiprotocol Label Switching

An LSP on a Nokia 7750 SR is configured for one-to-one FRR with node protection. Which statement is FALSE?

  • A Each PLR signals a protection tunnel that avoids the downstream node.
  • B A single protection tunnel can protect all LSPs that go through the same hop.
  • C A link protection tunnel is signaled if a node protection tunnel cannot be established.
  • D Protection tunnels used in this LSP are also detour tunnels.
Explanation

One-to-one FRR uses a separate RSVP-TE detour tunnel for each individual primary LSP. A protection tunnel shared by multiple LSPs is a facility-mode bypass tunnel, not a one-to-one detour.
