Ah, the 'carrier-carrier-vpn' command is the key to configuring the VPRN as a CSC. Glad they provided that detail in the options.

Hmm, the 'advertise-label vpn-ipv4' command makes sense for enabling VPN-IPv4 route advertisement. I wonder if there's any other way to handle the same scenario without that command.

But doesn't option B make sense because it disables loop detection?

The CSC VPRN configuration seems straightforward, but I'm curious about the loop detection functionality. Disabling it could be risky if the customer's sites have the same AS number.

A: I think disabling loop detection with the 'loop-detect off' command is necessary for the customer carrier with the same AS number.
