not rewriting next-hop, pointing default, ...

a senior engineer at a well-known provider just pointed out to us that a weenie provider at mae-east was o not rewriting next-hop o sending our routes to others o sending others' routes to us o likely pointing default at us their noc phone was answered by a modem. we suspended peering with them and wrote to their noc. we got back a snotty message. we have ceased peering with them. we installed packet filters. our traffic on the east fddi dropped noticeably. when the larger providers decline to peer with the smaller, there is a sad reason. traceroute -g is your friend. randy
