Question #: 96
Topic #: 9

A Cisco engineer is configuring MPLS VPN BGP at a customer site that is connected to the provider site by more than one path MPLS VPN BGP Local Convergence link protection is enabled. After the engineer installs the main forwarding path and the redundant backup path within the BGP, they assign a unique route distinguisher to each VRF table on all PE devices that serve as a backup to the link. What is a prerequisite for this local convergence to work?

AInterautonomous system option A (back-to-back VRF) is active.

BBGP must support lossless switchover between operational paths

I'm gonna go with D, the system is performing a PE-CE link protection on both ends. Sounds like the most comprehensive solution to me.

I'm not sure, but I think option A) Interautonomous system option A (back-to-back VRF) being active is also important for local convergence to work.

I agree with Dorthy. BGP supporting lossless switchover is crucial for this to work effectively.

Hmm, I think the answer is B. BGP must support lossless switchover between operational paths. That seems like a key requirement for local convergence to work.
