Has anyone put in place a method to identify if one their BGP peers suddenly withdraws X% of their prefixes? e.g I should expect ~420k prefixes in a "complete"[1] routing table from a transit peer today. If suddenly I'm only getting 390k prefixes I'd guess a major network was depeered or similiar. If so how are people doing this? SNMP MIB, screen scrape? [1] Varying levels of completeless apply.
