What is the relationship between Router 1 and Router 2?

ARouter 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

BRouter 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.

CRouter 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.

DRouter 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.

D sounds plausible. Router 2 learning from Router 1 is key.

C makes sense too. They both learn the topology together.

Hubert 12 days ago

I’m leaning towards B. Both routers are head-ends, right?

Luther 17 days ago

I think it's option A. Router 1 needs the topology info.

Precious 22 days ago

A has merit, but I still favor B for the head-end aspect.

Chau 27 days ago

I'm with D too. PCE on Router 1 is crucial.

C is interesting. They could both learn for peers.

Isadora 1 month ago

B feels right. Both routers as head-ends is logical.

Wilda 1 month ago

I lean towards A. Central learning is key for SR-TE.

Ngoc 2 months ago

I think it's D. Router 2 learns from Router 1. Makes sense.

Andree 2 months ago

I’m not sure about D, sounds a bit complicated for just one tunnel.

Louvenia 2 months ago

Wait, is Router 2 really just a node? That seems off.

Chantay 2 months ago

I thought both routers could be head-ends, so B could work too.

Eliz 2 months ago

Totally agree, option A makes the most sense!

Ula 2 months ago

Router 1 is the one learning the topology.

Alexis 3 months ago

Totally agree, option D makes the most sense!

Cristen 3 months ago

Router 1 is the PCE, right?

Carolynn 3 months ago

I feel like both routers learning the topology together is a common scenario, but I can't remember if that's what they meant in option C.

Sunshine 4 months ago

I practiced a similar question where one router was the head-end. I wonder if that's what they're asking here with option D.

Fletcher 4 months ago

I think option A sounds familiar, but I can't recall if Router 1 is the only one learning the topology.

Evelynn 5 months ago

I remember studying about SR-TE tunnels, but I'm not sure if both routers can be head-ends. That seems tricky.
