Marty, and others: Yes, the Ascend's are fundenmentally broken, BUT and this is a big one, there are work arounds for the problems with Ascend's broken routing protocols, i.e. don't use them, or filter them. This is easy enough to do. The problem is more general than Ascend however. There are MANY boxes out there (terminal servers) who's PPP is broken in this way. Telebit Netblazers and Livingston Portmasters included. It's kind of sad, really, when a small company like mine, can make this work and the "world's largest ISP" can't fix the problem. It is good to point out that other large ISPs have this same problem. >there are about a dozen ISP's extensively using ascend's which have this hole. > >our original RFP to them dealt with this issue > >but they did not execute > >they keep trying to fix this, but so far no go > >we have tried to keep this quiet so that > >microsoft/uunet/psinet/etc..... > >don't get extensively hacked > >we have had two occurences of this so far in one year that I know of though >there are probably more > >marty > >> PSI allows people to negotiate PPP addresses, and then >> propagates everything everywhere w/o even token filtering.
