Phil, The subnets you are receiving via your BGP session with DREN support the DoD HPCMP portions of the net at SC97. There is a DREN connection to SC97 to support the demonstrations. Therefore you should reach the DoD HPCMP resources at SC97 via your DREN connection, and the rest of your SC97 traffic should follow the less explicit 147.73/16 path. DREN is not announcing these subnets to other peers at the exchanges, only to DREN members. Meanwhile, in response to your message, Tom Kile installed a filter at PLK so you should no longer receive these prefixes via DREN. --Ron Begin forwarded message: To: [email protected] Subject: routing to 147.73/16 Date: Mon, 17 Nov 1997 13:04:07 -0700 From: Phil Wood <[email protected]> Sender: [email protected] Folks, If any of you BGP peer with DREN, as we do, you will be getting (as part of their AS668) a couple of subnets of 147.73/16: B 147.240.0.0/16 [5/0] via 138.18.169.1, 01:44:58 147.73.0.0/16 is variably subnetted, 2 subnets, 2 B 147.73.234.0/28 [5/0] via 138.18.169.1, 01:40:24 B 147.73.234.128/27 [5/0] via 138.18.169.1, 01:39:54 This could cause customers visiting SC97 to complain about connectivity to their local network from SC97 unless you are also receiving routing for the remaining 147.73 space from some other peer. I thought some subset of the nanog population might want to know since it caused me a bit of trouble shooting this morning, and nobody at DREN is available. Phil
