I’m not sure about DHCP relay being necessary here.

Subinterfaces with dot1q tagging are a must!

Wait, isn't IGMPv3 more for multicast?

Totally agree, B is the way to go!

I think BGP is essential for the underlay.

I vaguely recall something about DHCP relay, but I can't remember if it directly affects node discovery. This one's tricky!

I practiced a similar question where enabling subinterfaces was key for link configurations. Maybe option B is worth considering?

I'm not entirely sure, but I feel like IGMPv3 was mentioned in relation to multicast traffic. Could that be relevant here?

I remember discussing the importance of BGP in the underlay for Multi-Pod setups, so I think option D might be the right choice.

I'm fairly confident that the correct answer is option B, enabling subinterfaces with dot1q tagging on the links between the IPN routers. This should ensure the proper VLAN configuration for the new nodes to be discovered.

Okay, based on my understanding, the key here is to enable the proper connectivity and protocols between the IPN routers and Cisco ACI spine. I think option C, enabling DHCP relay, is the way to go.

Hmm, I'm a bit confused on the specifics of how the new nodes should be discoverable by the existing APICs. I'll need to review the Cisco ACI documentation to make sure I understand the correct approach.

This seems like a tricky question. I'll need to think through the Cisco ACI Multi-Pod configuration and disaster recovery process to determine the right action.

Ah, the old Cisco ACI Multi-Pod conundrum. I'd say option D is the way to go, but I'm still trying to figure out how to make my toaster work with it.

Hmm, I'm not sure. Isn't enabling subinterfaces with dot1q tagging on all links between the IPN routers a common practice for Cisco ACI Multi-Pod setups? Option B might be the way to go.

I agree, Option B might be the way to go for the new nodes to be discoverable.
KE

Yeah, that sounds like a common practice for Cisco ACI Multi-Pod setups.

I think enabling subinterfaces with dot1q tagging on all links between the IPN routers is a good idea.

Configuring IGMPv3 on the IPN routers? That's a bit like trying to catch a fish with a baseball bat. Option A doesn't sound right to me.
RE

Option C seems more logical to me. Enabling DHCP relay on the links connected to the Cisco ACI spines will ensure the new nodes can obtain the necessary configuration details.

That makes sense. DHCP relay can help in distributing the necessary information for the new nodes to be discoverable.

I think B) Enable subinterfaces with dot1q tagging on all links between the IPN routers makes the most sense for discoverability.
ME

I think option D is the correct answer. Configuring BGP as the underlay protocol in the IPN will allow the new nodes to be discovered by the existing APICs.
MA

I think we should go with option A, configuring IGMPv3 on the interfaces of IPN routers.
AL
Alyce

I agree, option D is the best choice for this scenario.
LA
Lashandra

I'm not sure, but I think enabling DHCP relay on all links connected to Cisco ACI spines could also work.
TH
Thora

I disagree, I believe the correct answer is D) Configure BGP as the underlay protocol in IPN.
DA

I think the answer is A) Configure IGMPv3 on the interfaces of IPN routers that face the Cisco ACI spine.
