BThe PE has proxy-ARP and dynamic-populate enabled for the VPLS.

CThe proxy-ARP table is populated by snooping IP packets received from remote PEs.

DWhen the PE learns a local host IP address, it adds an entry into its proxy-ARP table.

EThe PE advertises a MAC/IP route that includes the MAC and IP address of a local host.

Show Suggested Answer

Suggested Answer: A

The local AC tag ID configured on PE2 must match the local AC tag ID configured on PE1. This ensures that the tag IDs are consistent across both ends of the VPWS service.The remote AC tag ID configured on PE2 does not need to match the remote AC tag ID configured on PE3, as long as they are unique within each PE1.

Wait, are we supposed to be learning about proxy-ARP or proxy-IP? I'm getting a bit confused here.

This question is a real brain-teaser! I hope I can remember the difference between ARP and IP packets for the exam.

So, the proxy-ARP table is not populated by snooping IP packets from remote PEs.

That's correct! The PE actually learns local host IP addresses and adds them to its proxy-ARP table.

Option B seems to be the false statement. The PE has proxy-ARP and dynamic-populate enabled for the VPLS, not the other way around.

I think Option D is the correct answer. The PE adds an entry into its proxy-ARP table when it learns a local host's IP address.

I believe the correct answer is C) as well, because proxy-ARP is based on ARP requests, not IP packets.
