It sounds like what is happening, is that, outbound, it's obviously taking the correct link. When the return traffic comes back, other BGP routers, are choosing the path through the other ISP. This can happen because of a veriety of different reasons.
Are you advertsing out any networks via BGP, or is this extra link, simply for redundancy. I'm assuming you're advertising different networks out.
If the above is true, then you will need to tell Internet BGP routers, that you have attributes that will make the second link undesirable, so that return traffic goes through ISP1.
The best way to accomplish this IMO, is my pre-pending your AS. So if your local AS is 100, other routers will see just , when being advertised out each network. You can pre-pend it by [100. 100. 100] through your second ISP, when advertising your networks, thereby making it less desirable, and return traffic will come through ISP1.
I'll take a look at the wireshark file, one I get to work, while drinking coffee unless someone beats me too it.
send us a traceroute mate, for the rest, Are you saying you have no BGP between your 2911 that connects you with CE_VSAT_IDU? In which case you will not be able to influence the upstream path, using AS path prepending.
In which case, you will probably have to liaise with your provider and re-iterate your requirements.

CE_VSAT_IDU is managed by ISP, they only provide me IP address for my use. Now i have two way to use it First one is i connect that link in switch and give each client(PC) manual IP address in rage of device(CE_VSAT_IDU) that is very hectic, Second one is terminate link in router and configure STATIC ROUTE with METRIC value.
I choose the second way and configuration that i done on router are correct. As we told our ISP after configuring CE_VSAT_IDU we are facing such problem that whenever user send data out to our network then it goes from primary path(MPLS) but when user receive data it comes from secondary ISP (CE_VSAT_IDU). After troubleshoot by ISP the problem get resolved. Now both path working fine.
ISP1(MPLS_VPN network) Service provider BSNL
ISP2(VSAT)Service provider BSNL
My worry is i want to know what was the issue is this. Because ISP don't share this issue with us.
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
