out of 47000 routes from Agis, 7327 of them have 7007 in them. I spoke to them and they said that thier router broke.. They won't give us an answer, but when I said I was from Net Access, he said "nac.net?" like he knew me, and they were vague. They also claimed that they had 'turned thier router off', but the routes were still in for almost 25 minutes later. Not only that, it seemed mailcious to me, because the only announced the /24 of our name servers (207.99.0.0/24) and not our whole /17. VERY STRANGE. AND THEY WON'T ANSWER ANY QUESTIONS.

we are seeing lots of routes coming in
sho ip bgp sum BGP table version is 6699646, main routing table version 6699646 49793 network entries (94886/99644 paths) using 8897576 bytes of memory 11894 BGP path attribute entries using 1541824 bytes of memory
but the routes seem to be coming from AS 7007... They are advertising many routes, even our own. Sorry, but email and phones to them isn't working.

Are your nameservers in the first class C of your CIDR block by any chance??? They have been taking CIDR blocks and squirting out Class C equivilents. Sadly, many poeple (including me) think, oooh, nice big CDIR block lets put all my important boxes in it's first Class C... Seems to be a very bad descision ;-( Regards, aid -- Adrian J Bool | http://www.u-net.net/ Network Operations | mailto:aid@u-net.net U-NET Ltd | tel://+44.1925.484461/

And, because of the way you get CIDR allocations in Europe (and probably everywhere else now) Join RIPE Apply for space for your own network This gets allocated from the beginning of a new /19 CIDR block Build NOC and 1st POP Then start applying-for/allocating customer address space I would imagine a very large proportion of "newer" ISPs have critical stuff in the 1st /24 of their 1st allocation ...

I know from the time that I worked at RIPE, that there were at least some 'weird' people that asked if we/they could start assigning from the top of the /19 ..., and we accepted that. May be they were right after all ;-), David K. ---

They announced the first classful block from all CIDRs in the table. For example, if I had 172.16.0.0/14, 172.16.0.0/16 would have been announced. I venture to take a guess that it's something nasty with redistribution of BGP into a classful IGP and back into BGP again, but since it's not my network, I can't tell you what happened. /cah
