Now i have configured Natting on Router A for a local subnet to subnet range 10.16.22.16/29 and created a loopback interface on Router A having ip from subnet 10.16.22.16/29(this is done bcz i need to publish this range to remote end Router B through BGP which i am accessing through ISP and on the same range i am natting on the local router i.e. Router-A). Now at the Router B my customer sees route for 10.16.22.16/29 in bgp table as *d, so this subnet is not reachable from Router B, now please help me out why this is happening, is ISP dampenning this route or some other problem.
I contacted ISP and he is able to ping my NAT subnet from his PE router which is connected to CE router of customer, means he is seeing that subnet in BGP table with a valid path, i will contact the customer for getting his router details but its very strange that this subnet is installed in ISP VRF and not reaching rather dampped at customer router.
Actually the dampenging should be happening on router-B end. ISP can see the route and it is installing that route in its BGP table as well as it is passing the route to router-B as well but if dampening is configured on router-B and route flapped, route will be removed from the table and will be in dampened state.
Issue is resolved now, i dont know whether customer did something or it was done from ISP end, but whatever i have read in books and got to know from other people who are working in ISPs that usually ISP do route dampening so as to restrict route flapping to be passed from their customer to internet and other AS.
Anyhow thanks to everybody who participated with the intentions to help resolving this issue.
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
