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.

Haha, imagine if the answer was option C - 'IP/GRE is enabled'. That would be a real head-scratcher!

I'm leaning towards option B. If the BGP doesn't support lossless switchover between paths, then the local convergence won't work, right?

Let's see, the key here is that local convergence is enabled, which means we're talking about a redundant backup path. I think the answer has to be related to that.

Hmm, this question seems pretty tricky. I'm not entirely sure about the prerequisites for local convergence in MPLS VPN BGP with redundant paths.
