Each SDP with a Backbone MAC is definitely the way to go!

B-VPLS is key for Backbone MACs, not just I-VPLS!

Wait, so only one MAC is learned in the core? That seems odd.
RE

Totally agree, that's how it limits MAC addresses!

I-VPLS uses an l-MAC in the core, right?

I feel like D could be correct since it mentions SAPs and l-MACs, but I’m a bit confused about how they relate to limiting MAC addresses.
DO

C sounds familiar because I remember discussing Backbone MACs hiding customer MACs, but I’m not confident it’s the right choice.

I recall something about B-VPLS and l-VPLS from practice questions, but I can't remember if they specifically limit MAC addresses in the core.

I think the answer might be A, but I'm not entirely sure if I remember the specifics about l-MAC addresses.

Ah, I see. The Backbone MAC is used to hide the customer MAC addresses in the core, so the answer must be C. Each SDP is configured with a Backbone MAC for this purpose.
RE

I'm feeling pretty confident about this one. I think the answer is A. The I-VPLS is configured in the core with an l-MAC address, and that's the only MAC address learned in the core.

Okay, let me think this through. I believe the key is that the function in IEEE 802.1ah is designed to limit the number of MAC addresses learned in the core. So the answer is likely related to either the l-MAC address or the Backbone MAC.

Hmm, I'm a bit confused on this one. I think it might be related to the I-VPLS or the Backbone MAC, but I'm not entirely sure which one is the correct answer.

I'm pretty sure the answer is B. The B-VPLS and l-VPLS are configured in the edge, and the B-VPLS is the only MAC learned in the core.

Hiding customer MAC addresses in the core? Sounds like the network is playing a game of hide-and-seek. Where's Waldo?

C) Each SDP is configured with a Backbone MAC to hide customer MAC addresses in the core

B) The B-VPLS and l-VPLS are configured in the edge. The B-VPLS is configured with a Backbone MAC and is the only MAC learned in the core
RY

A) I-VPLS is configured in the core of the network with an l-MAC address. This l-MAC address is the only MAC learned in the core

Option A? Really? That's like trying to fit a square peg in a round hole. Let's stick to the actual IEEE 802.1ah functions, shall we?

D) Each SAP is associated with a common l-MAC to hide customer MAC addresses in the core

I'm a bit torn between B and D, but I think I'll go with B. It just makes more sense to me to have the Backbone MAC at the edge rather than associating each SAP with a common l-MAC.

User 3: Definitely, it simplifies the network architecture.
SH

User 2: Yeah, I agree. It helps limit the amount of MAC addresses learned in the core.
LE
Leatha

User 1: I think B is the correct answer too. Having the Backbone MAC at the edge seems more logical.
ET

I'm going with option C. Configuring each SDP with a Backbone MAC is a great way to hide the customer MAC addresses and keep the core clean.
SY
Sylvie

Agreed, it's important to keep the core network clean and secure.
MA
Marti

True, both options C and D help limit the amount of MAC addresses learned in the core.
TE

I think option D could also work. Associating each SAP with a common l-MAC can hide customer MAC addresses too.
DO
Donte

Option C is a good choice. It helps keep the core clean by hiding customer MAC addresses.
PH
Phyliss

Option B seems the most logical choice here. By configuring the B-VPLS with a Backbone MAC, the customer MAC addresses are hidden from the core, limiting the number of MAC addresses that need to be learned.
