"I don't have full mesh between all peers"

So, you're saying all your iBGP peers are not known to each other or are you saying you don't have a full physical mesh?  If the former, that's a problem.

Hi,

generally, I see 3 possibilities here:

1) To configure a logical iBGP full-mesh among all your routers.

I.e., to add iBGP sessions from DR to that 3 remianing routers and an iBGP session between WAN-01 and Second DC.

2) To use eBGP where full-mesh is missing.

I.e., move the DR router to AS 65501 and Second DC to AS 65502, e.g.

This looks to me to be the easiest way.

3) Configure route-reflectors or BGP confederations.

Also a possibility, but a little more complicated.

Best regards,

Milan
