BGP Advertisements Harassing Server

Sun Jan 15, 2017 8:16 am

We have a problem that we are being throttled off / kicked off from our upstream BGP Peers because of the below.

I'm not sure what is causing it - but every couple of seconds the router is advertising the same route. For the sake of this issue - you can ignore the strange next-hop, and file exists issues - this is simply about the sheer volume of advertisements (using the timestamp as a reference for frequency)

Any ideas / places to look?

if you just want to suppress this advertisement - do it using a route-filter.

I need the advertisement, just not every five seconds
