I wasn't saying it was good, I said it was first, which it was. According to my reading (reading only, I haven't looked at code) the split horizon with poisoned reverse idea is supposed to let it learn about dead routes far quicker ... pure distance vector would do that. I don't know what's actually in routed yet, and academic books are often completely out to lunch, I'm finding. > > -Matt > Matthew Dillon > > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@picnic.mat.net | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run picnic (FreeBSD-current) (301) 220-2114 | and jaunt (Solaris7). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
