I thought it was the service label in the MPLS header?

The multicast B-DA mapping is crucial too, don't forget that!

Wait, are we sure about that? Sounds a bit off.

It's all about checking the l-SID in the l-TAG.

I’m leaning towards D because it mentions checking the multicast B-DA, which seems relevant for forwarding multicast traffic.

I’m a bit confused about the difference between l-SID and l-TAG in this context. Could it be A instead of B?

I remember practicing a question similar to this, and I feel like it had to do with checking the l-TAG for local VPLS.

I think the answer might be B, but I'm not entirely sure if it's the l-SID or l-TAG that gets checked first.

Ah, I see now. The key is to identify the unique capabilities of each model. I'll compare the details provided in the options to determine the true statement.

I'm feeling a bit lost on this one. The wording about "sendable data extension" and "relates to" is throwing me off. I'll need to re-read the question and options carefully.

This seems like a straightforward question, I think the answer is B - Reinstall a second Cisco Unified CCX node and add it to the cluster over WAN.
