Hi All
I am trying to get two routers working together on ISDN Sbus using the
Dialer Map command.
I have a topology of:
Ethernet 10.10.10.0 /24------> R5 <------ISDN SBUS 10.30.10.0 /24 -----> R3
<-------10.20.10.0 /24
Yes it looks simple and I got it to work with Dialer string command but it
fails now I have changed to a dialer map configuration.
A ping fails from either end, with debug ip packet reporting encap errors.
My 'sh dialer map' looks good and the configs look in line with every bit of
doc I can find., but the router who should be responding to the ping is
failing to make a connection.
The line is configured for multipoint support and I know it to be good
(worked earlier for Dialer String config)
Any Clues?
Thanks

This shows the dialer successful for the guy sending the ping (R5), but
failed for the R3 who shows up encapsualrion failures - why would the
connection fail...?
