iBGP over external channel is it possible

[Anatoly Fanrus]

Hello,

Help me pls,

is it possible to connect over iBGP some geo-sites over external link without dedicated internal link between locations?

Let there is three sites and each site connected to Internet but threre is no connection over WAN link between sites. 

Thanks in advance

As per my understanding you can do it with Same As no, but the IP must be reachable and TCP port 179 is open.

Yew that is correct. You need to have IP reachability and the same AS. BGP does not care for everything else.

Not entirely sure what you are asking but you can run BGP over a GRE tunnel.

Yes Over Tunnel it is possible.
