Hi all, I'd like to ask an advice on this case. This is about a peering session at RRC0 with AS7018 (12.0.1.63). They're saying that they recently do not receive the announcements/withdrawals of the beacon prefix 195.80.224.0/24. Apparently, the last time they noticed the flapping of this prefix was in the beginning of June 2004. In fact, looking at the RIS database, we can see the daily updates of the other RRC0 peers for 195.80.224.0/24, but none from AS7018. The peering session with them has been up for about 3 weeks. How can we check whether the BGP updates are being sent to them or not?

Cc: Aman Shaikh <ashaikh@research.att.com> Message-Id: <16731.13504.826194.244753@oz.mt.att.com> Hi, We've got a BGP session from our 12.0.1.63 to your 193.0.4.28. I thought that 195.80.224.0/24 was supposed to oscillate based on the schedule at http://www.ripe.net/ris/beaconlist.html, but I haven't seen that prefix flap since sometime in early June 2004. Below I'll include what I've got now.
