Question
Click on the exhibit. An LDP tunnel is established on router R1 towards router R6. The link between routers R2 and R4 goes down. What will happen to the MPLS data traffic to router R6 IMMEDIATELY after the link goes down?
Exhibit
Options
- AMPLS data traffic will be discarded until the IGP finds a new next-hop to router R3.
- BMPLS data traffic will be discarded unless the LDP tunnel has a standby secondary path.
- CMPLS data traffic will not be discarded because router R1 received labels from both next-hops, routers R2 and R3.
- DMPLS data traffic will not be discarded because of fast reroute capability on router R2.
