At SC97, we saw 147.73/16 injected into the vBNS yesterday by DREN. this caused vBNS sites to traverse the vBNS to SDSC then hop to DREN to get to SJCC while the vBNS/NTON link into SJ was being worked on. this was quite unexpected. lw At 08:25 AM 11/19/97 -0800, Ron Broersma wrote: >Phil, > >The subnets you are receiving via your BGP session with DREN support the DoD >HPCMP portions of the net at SC97.
