Hi We are a ISP in South Africa and have a problem we are trying to figure out rather urgently, without much success so far. We are currently multi-homed during the day and tripple homed at night. (our peaks are at night and we get cheap bandwidth from another ISP who has their peak in the day). Internic has refused to give us our own block of addresses which would have made thins much simpler. (despite repeated attempts, and we now have 7 /24's from various places and badly need more). Basicaly we (AS6180) have been announcing all our adresses including 196.25.116.0, 196.25.117.0 and 196.25.203.0 via AS 3741 at night, and this gets switched of during the day. The problem seems to relate to the fact that these addresses are part of AS 5713's CIDR 196.25.0.0/16 and we thought we could get away with announcing them like this. It did work fine for over a week, but now today we have a problem. MAE-East (see example at end of message) , the Sprintnap and who knows who else still have entries for these via AS3741 but they are showing as received-only, and no best path. Yet via MAE West they are fine. We are going to stop announcing these via AS3741 at night, but its been 9 hours now since they were not announced and these received-only entries are still sitting there blocking these routes from it seems about a third of the internet. Can any one offer any comments on why they are still there, what received-only means and how we can get if fixed? Many thanks Regards Anthony Walker MAE-East Looking Glass Results Query: bgp Addr: 196.25.203.0 BGP routing table entry for 196.25.203.0/24, version 5006458 Paths: (1 available, no best path, advertised over IBGP) 1673 1239 4005 3741 6180, (received-only) 192.41.177.141 from 192.41.177.141 (140.223.57.217) Origin IGP, external
