Site A and B with backdoor link connected to MPLS with different AS#

[kondzio24]

Hello,

Two sites are connected to L3 MPLS with different AS#. We are doing eBGP with the provider and doing OSPF redistribution from BGP on the backend. There is also dark fiber between the two sites that is used as a backdoor link.

I would like to make on site A primary and have all traffic from both locations (using backdoor link) go in and out of the two sites. Site B will be used in an event of MPLS failure at site A.

Any suggestions please on how to accomplish this task without changing both sites to use the same AS and then simply prepend AS number from site B to make it less preferable? I would like to stay and use different AS numbers at each location.

Thanks in advance.

Hello,

I think your question is somewhat unclear. Can you draw out your current setup and indicate what you are trying to accomplish ?

Hi

Is the backdoor link being used with any IGP or static routes?
