We have two BGP neighbors with two different carriers MPLS IP VPN products that are advertising private LANs to us (ie. 172.16.x.x/24). We are able to reach the various sites private networks from our core routers but unable to reach the private network from the different AS network spokes.
For example I have a site on carrier A on the 172.16.102.x network that only receives routes from other carrier A routes but doesn't receive the routes advertised via BGP on carrier B. So what is the best method to get the carrier B advertised BGP routes redistributed to carrier A and vice-versa.
I assume these two bgp neighbors on the same router? If so, unless you are filtering the routes you advertise to each one of these neighbors, the routes received from one should be advertised to the other and vice versa.

if the the BGP neigbours are on different customer routers, there is a BGP session necessary between the customer routers to get the carrier B advertised BGP routes redistributed to carrier A and vice-versa.
There might be some problems with clashing AS numbers though, if both providers would be using the same private AS numbers for their customers, e.g.
Both ASes are on the same router and they are in deed different ASNs. Yet when trying to get to the private LANs that are advertised from one service prodivder to another LAN advertised on the other service prodivder it is not working.
