Haha, I hope the exam doesn't ask us to configure LDP FRR on our routers. That would be a nightmare!

I agree with Alease. The key purpose of LDP FRR is to provide fast recovery in case the primary LSP flaps.

I'm a bit confused about B and C. Does LDP FRR really work on both ingress and intermediate nodes? And can it back up multiple LSPs? This needs some clarification.

A and D seem to be the correct statements. LDP FRR definitely generates a backup LSP to protect against primary LSP failures.

B) LDP FRR can be deployed on the ingress node and the intermediate node. The primary and backup LSPs are recorded in the ILM table on the intermediate node and in the FIB table on the ingress node.

Yes, A and D are correct. LDP FRR does create a backup LSP for protection.

D) After LDP FRR is enabled, a backup LSP can be generated for a primary LSP to prevent serious packet loss during fast flapping of the primary LSP

A) After LDP FRR is enabled, a backup LSP is generated. Both the primary and backup LSPs are stored in the forwarding table.
