Hi -

I'm trying to rewrite cisco configs for a very small client with cisco
routers, frame, and isdn dial backup. They are using both ipx (rip) and
ip (eigrp).

I'm using floating static ip and ipx routes to cause the isdn interface
to dial when there is interesting traffic and the frame interface is
down. It works fine. When the frame connection is down and the dial
connection is up, I can see ipx saps on the remote network (i.e, each
router knows about saps on the remote net). When the dial circuit drops,
the ipx rip routes are removed in 240 sec (so far, so good) but the saps
disappear at the same time, despite:

1. the "ipx update interval sap changes-only" command in the dialer
interfaces, and
2. the floating static routes to the ipx net with the ipx server
3. the dial map command in each dial interface that shows the phone
number for the remote dialer interface

Why, when the rip routes age out, aren't the floating static routes
sufficient for keeping the saps in the sap table? 

As an alternative, I've tried running ipx eigrp on my frame connection
and ipx rip with snapshot routing on my dial up ... the theory being
that when the frame connection drops and the eigrp routes go away, the
snapshot rip routes will be there, but no dice! I guess IPX
administrative distance doesn't work like IP? Or perhaps IPX RIP routes
can only be installed in the ipx route table when they are learned?

Help, my brain hurts!

Thanks in advance!
