If a transit link goes, for example because we had to reboot a router, traffic is supposed to reroute to the remaining transit links. Internally our network handles this fairly fast for egress traffic. However the problem is the ingress traffic - it can be 5 to 15 minutes before everything has settled down. This is the time before everyone else on the internet has processed that they will have to switch to your alternate transit. The only solution I know of is to have redundant links to all transits.
Alternatively, if you reboot a router, perhaps you could first shutdown the eBGP sessions, then wait 5 to 10 minutes for the traffic to drain away (should be visible in your NMS stats), and then proceed with the maintenance? Of course this only works for planned reboots, not suprise reboots. Kind regards, Job
