Doing BGP in local with a remote IX

General questions

Hi there,

I have a situation that I am not sure how to make things work, so I would need some hands here.

We have two sites.

A is where we do our maing BGP and connect to our upstream.
B is a remote site that we have Internet Exchange fiber, connected to a VYOS router.

I want to ask that is it possible to access to the IPs assigned by the IX on Site B, in our Site A, where we do our main BGP.

Basically I want to be able to connect to the IX remotely without losing connectivity to the prefixes we have in our Site A.

We connect site A to site B via GRE tunnel and do an iBGP, but when advertising the prefixes to the IX via GRE tunnel BGP session, when a request hit to the IX, that connection lost, it does not reach to our main routing table at site A.

I hope I was able to explain it well, if not, please feel free to ask questions to clarify.

If my approach is wrong, I would be grateful if someone can shed a light towards right direction.

Both routers are on VyOS 1.4.0.

Cheers,
Vin

The question is not related VyOS. Why not ask your IX ISP?

Both routers on site A and site B are running vyos. How come is not related to VYOS?

Basically the question is connecting 2 vyos boxes and being able to communicate IX IPs (site B) from our main location (site A)

It is not question to VyOS :wink:

Because the configuration on two site isn’t proper.

So that’s a configuration question as how to connect two sites properly, so from site A we can ping local IX IP at site B.

Please help me to delete the thread, I’ll rearrange things and open a new one with a clearer explanations.
