As per attached diagrm from Router A I can reach to 10.10.10.2 but from any other router I can't when I do tracert from any other router it goes to router B then stops. for every router in sh ip route 10.10.10.0/30 it shows learn through A. We use BGP as Protocol
It could be a number of things but the most obvious thing to check first is does the CE router have routes back to the source IP addresses of the other routers ie.
when you ping from Router A, router A will use it's 10.10.10.1 interface so the CE router knows how to get back to this. But when you ping from another router it will not be using an address from the 10.10.10.x range so does the CE have routes for the relevant source IP addresses ?
This would be one thing to try and if the problem is that the CE router doesn't know how to get back to the other routers then the default route would fix your problem.
However this is only one way to fix it. Without more details about routing protocols, redistribution etc. it's difficult to say.
Try adding default route and see if that solves the problem. If it does then you know it is a routing issue on CE router. You can then decide whether you just want to stick with default route or whether you want to investigate a bit more.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
