Hi Guys, Was anyone else seeing anything weird going on today? I have an OC-3 to Qwest, and another OC-3 to Level3, (among 2 others to different providers) and when all was well, I was receiving a little over 221,000 prefixes from L3. Then, intermittently I would start losing prefixes from L3 and it would get down to a little over 220,000. When this happened, I noticed I was having intermittent connectivity issues (atleast to one IP I was trying to get to). Doing a traceroute during the "outage" the packets would hit Qwest's network, then L3's, then drop, or sometimes not. I have since admin downed my BGP peer to L3 and everything has stabilized, but I was wondering if anyone else saw anything going on?
I think there was something going on between Qwest and L3, I saw the same thing with traffic coming from a network I have equipment on which is connected with Qwest and tracing to our home AS which has L3 amongst others. I set a community for L3 to not advertise my prefixes to Qwest to get around it. It appears back to normal now though, I just tested. Dave
