James, Your 611123300 wierdo is actually just another way of representing 9325:100. It is really two sixteen bit values added together eg. 9325*65536 = 611123200 + 100 = 611123300 ( your answer) To change this representation you need to enter the IOS command: ip bgp-community new-format Cheers Ben

We have a router in Christchurch that seems to be sending community attributes to an EBGP peer, even though the neighbor statements dont contain the send-community argument. Does anyone know whats causing it?
The router is running version 12.0(7)S1 on a 7500 series chasis.
Also, on a somewhat related note, all domestic routes learned over WIX are being tagged with the community 9325:100, which is all cool. Our wix router does this:
IPNWN1-B1#sh ip bgp 202.10.80.0 BGP routing table entry for 202.10.80.0/20, version 457621 Paths: (1 available, best #1, table Default-IP-Routing-Table) Advertised to non peer-group peers: 202.27.158.248 202.27.176.3 202.27.176.6 202.27.176.7 202.27.176.12 203.96.111.254 9718 202.7.0.78 from 202.7.0.78 (202.10.65.24) Origin IGP, metric 0, localpref 100, valid, external, best Community: 9325:100
The christchurch router says this:
IPNCH1-B6#sh ip bgp 202.10.80.0 BGP routing table entry for 202.10.80.0/20, version 82178 Paths: (1 available, best #1) Advertised to non peer-group peers: 202.36.174.82 9718 202.7.0.78 (metric 179712) from 202.27.176.4 (202.27.185.135) Origin IGP, metric 0, localpref 100, valid, internal, best Community: 611123300 ^^^^^^^^^ - what is this?!?!? shouldnt it be 9325:100??
Any ideas anyone has would be helpful.
