I have a scenario which, I'm not able to figure out the solutions.
Please see the problem statement below:
I have 3 link from 2 different ISP and running BGP. All 3 neighbour gives me default route only.
Out of 3 links, 2 are STM and 1 is DS3.
Now to build redundancy in case of failover, I used as-path prepending. However, my ISP says that it won't work because of the multi-homing and other stuff. In short they will not do anything even if longer as-path is coming though their peer.
As a solution I thought to go for conditional advertisement.
But my bad luck is that since I have 2 link from same ISP having same as-path and only default route, I'm not able to think out how to differentiate whether STM link has gone done or DS3 link has gone done and apply that in AVERTISE-MAP NON-EXIST-MAP solution.
