Thanks Mike. My lab date is 13 Jan.
This is a great link. There was a caveat that told me this is not the solution
I'm looking for. There is no way to keep the line idle.
One significant problem with AppleTalk through a GRE is that the routing protoc
ol will keep the line up, and there is no way to mask it out of the dialer map,
since the dialer interface sees all the GRE traffic as simple IP packets. The
only way to manage this is to turn the box off when not in service. At first gl
ance, it appears possible to exclude all GRE traffic and use some other traffic
to bring up the line, but inspection shows that the GRE traffic--and, therefor
e, the AppleTalk traffic--will not keep the connection from idling out, either.
There is, therefore, no solution to this problem other than turning off the ro
uter when not in service.
Regards,
Charles

Subject: Re: apple dialer-list
if you are taking the lab after 1 Feb then you shouldn't have to worry
about it. If before then, have you tried using GRE tunnels. Because a
tunnel interface has a default bandwidth of 9k, your normal serial line
would be a more preferred route. When it failes the packets will be
encapsulated and follow the tunnel through the backup line. Anyway, i have
tried this in this on production networks and it works really well for no
allowing chatty protocols to keep up an expensive dialup line. This
technique also works well with IPX. here is a link that might help.
