Have you tried setting a hold queue on your ISDN.
That will cause the packets to wait for the line to come up in a buffer.
Thanks

Subject: EIGRP/VPN question
I have a GRE tunnel between 2 routers. Between the 2 routers I also have 1
serial and 1 isdn interface. The isdn is set up to do ddr with OSPF when the
serial goes down. Now I want to put EIGRP on the tunnel interfaces only.
This keeps the isdn up when the serial is down due to routing updates. I
tried to change the timers on EIGRP - hello and hold. This worked for a
while but eigrp neighbors dropped as hellos are not properly passed. I think
what is happening is that the first (and only hello) is dropped because of
the delay in line coming up. If I could only keep that packet there waiting
for .5 of a second it would work.
Any ideas or other solutions.
Thanks.
