C is the way to go for IBGP, totally agree!

Wait, D says IGP is required? That seems off.

B sounds right, multipath is key for load balancing.

I disagree, A is not true. No static routes needed for EBGP.
KA

C is definitely correct, helps with scalability.

I remember that using an IGP isn't mandatory for EBGP underlay, so I think option D is definitely incorrect.
LA

I’m uncertain about the multipath multiple-as parameter; it sounds familiar, but I can't recall if it's specifically required for EBGP underlay.
LO
Loren

I feel like I've seen a question about route reflection and IBGP scalability before, so maybe option C is correct?
KE

I think I remember that static routes aren't necessary for EBGP neighbors to establish, but I'm not completely sure.

Ah, this is a good one. I've worked with BGP in IP fabrics before, so I think I can apply that knowledge to identify the correct statements. Time to put on my thinking cap.

I remember learning about BGP in the underlay, but I'm not sure I fully understand the requirements for EBGP versus IBGP. I'll need to review my notes to make sure I get this right.

Okay, let's see. I know BGP can be used as the underlay routing protocol, and I think Route Reflection is related to IBGP scalability. I'll give it my best shot.
AN

Hmm, I'm a bit unsure about the differences between EBGP and IBGP in an IP fabric. I'll need to think through the details carefully.
HU

This question seems pretty straightforward. I'm confident I can figure out the correct answers.
FA
Fausto

I think option D is incorrect because using an IGP is not required for an EBGP underlay.
HA
Halina

I'm not sure about option A. Do we really need static routes for EBGP neighbors?
CA

Haha, underlay routing with BGP? That's like driving a Ferrari on gravel roads. But if you must, then B and C are the way to go. Gotta get that load-balancing and control plane scalability dialed in, am I right?
DE

Agreed, it's all about finding the right balance for your network.
JA

Definitely, those features are key for optimizing performance and scalability.
GI

Yeah, BGP underlay can be tricky, but multipath and route reflection can really help.
DE

I agree with you, Fausto. I also think option B is correct because multipath can improve load balancing.
FA
Fausto

I think option C is correct because Route Reflection can help with scalability.

Hmm, I think A and D are the right answers. You gotta have those static routes for the EBGP peerings, and an IGP is usually a must-have. B and C are just too advanced for the underlay, in my opinion.
LY
Lyndia

B and C might be too advanced for the underlay, as you mentioned.
TA

Static routes are indeed required for EBGP neighbors to establish, and using an IGP is necessary for an EBGP underlay.
MA
Madalyn

I agree, A and D are the correct choices for using BGP as the underlay routing protocol.
ZO

B is the key here. EBGP underlay needs that multipath multiple-as parameter to handle the load-balancing. C is also spot on - Route Reflection is super useful for the control plane in this scenario.
BR
Broderick

Using an IGP is not required for an EBGP underlay, so D is incorrect.
PH

Route Reflection is a great tool for control plane scalability in an IBGP underlay.
PR

B is definitely important for load-balancing in EBGP underlay.
IV

A and C are definitely correct. BGP is a great choice for the underlay, and Route Reflection can help with scalability. But D seems a bit off - I've seen EBGP underlays work just fine without an IGP.
