Hi, I need advice on how to have a fast converging failover from my upstream Internet providers. I am an ISP with three Internet upstream providers. I am running BGP with them. Currently I am load sharing my Internet traffic by advertising some of my /24s via one ISP and some via the others. However, as a backup, I advertise the supernet(s) via all links so that in case one of the links go down, traffic should return via the supernet. But it seems that after one /24 advertisement stops reaching the Internet, traffic of that prefix comes via the supernet advertisement after quite a while (even upto 30 mins). What is the reason for this behavior and how can I design for a faster convergence in such a case (i.e. one of my upstream link goes down)?
Thanks. Regards, Junaid _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
