I saw this type of behavior once with a back-to-back frame relay configuration. The connection was working to start with, but then I upgraded one router to a 12.0(x) release and the two routers stopped speaking to each other. The older router was running an 11.1(x) release. I upgraded it to a newer release and all was well. Perhaps you have a similar issue? Have you tried using HDLC instead of PPP just to see if the link will stay up?

I've spent many a night (late !!!) with these AGS Up/Down Serial interfaces. I've I wasn't so sure the router would pull my back out, I would have pitched it :o) Phil ----- Original Message ----- From: "Tim Medley" To: Sent: Tuesday, July 03, 2001 10:51 AM Subject: AGS+ crossed over to 2610, Serial cable length issue?
