Monitor and react. That could be automated or manual.
The BGP route optimizers could shut off that peer when they detect issues. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Nate Burke" <n...@blastcomm.com> To: "Animal Farm" <af@af.afmug.com> Sent: Tuesday, November 15, 2022 2:08:51 PM Subject: [AFMUG] Protecting Upstream Connections Ran into a problem today where one of my upstreams (windstream) was still advertising my IP blocks out to the internet, but wasn't routing all the traffic to me. I was still taking in traffic, but, for example, Google couldn't get to me on IP Blocks advertized via windstream. Took a while to track down what was happening and then manually turn off the Windstream BGP neighbor, which luckily fixed the problem once the subnet advertisements finally timed out and traffic shifted to other providers, which took a good 5-10 minutes. Is there a way to protect against that? My BGP Session to Windstream was still up and running, but something broke farther up in the Windstream network. Is the only method in that scenario to Just monitor and react? -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
