Hi all,
I'm trying to trigger alerts when BGP prefixes decrease.
In some cases, when there is an outage on ISP's circuit, the BGP adjacency doesn't go DOWN, but instead just the prefixes decrease, for example, from 1000 to 1.
Is there any way to check the BGP prefixes for a session, and when prefixes are lower than 10, for example, to have an alert?
Thanks.
