The problem is that the PPP link layer is required to deliver packets in order. When you go from MP encapsulating packets to not MP encapsulating packets (or vice-versa) you can't guarantee that the peer will deliver the packets in the same order that you sent them without being careful. This is mainly a problem when going from 1 -> 2 links I believe... or when mixing MP and non-MP over multiple links. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
