Cisco Exam 300-610 Topic 7 Question 78 Discussion

Actual exam question for Cisco's 300-610 exam

Question #: 78
Topic #: 7

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

CIP/GRE is enabled.

DThe system is performing a PE-CE link protection on both ends

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?

Good discussion. Option B it is for the prerequisite of local convergence to work.

Definitely. Option B is crucial for ensuring the redundancy and reliability of the network.

So, it's important to have that BGP support in place for effective local convergence.

Absolutely. The whole point of local convergence is to ensure minimal disruption in case of a failure.

That makes sense. We need a reliable way for the backup path to kick in if the main path fails.

Yes, you're right. Without support for lossless switchover, the backup path won't be able to take over seamlessly.

I think option B is correct. BGP must support lossless switchover between paths for local convergence to work.

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.
