Hi everyone,
I have been working on a ISDN backup scenario, where IPX can traverse the
ISDN line at all time, and IP only when the frame interface goes down. This
scenario has to use Dialer profiles because of requirements. I have
configured what I feel to be a correct configuration using dialer watch, and
snapshot for IPX.
Any way my IPX dialer interface is fine, I can ping and everything. But my
IP dialer interface can't ping the remote side of the ISDN link. I see
where the dialer binds to the bri interface but when I do a debug ip packet
I get encapsulation failed. Both sides are using ppp so I don't understand
where the encapsulation failed is pointing to. I am posting my configs.
Any help will be appreciated. The routers are r5 (Called router) and r6
(Calling router). The primary line is the Serial 0 subinterfaces on both
routers r6 is p-to-p and r5 is multipoint. if this goes down it should
bring up the ISDN line for IP.
Thanks in advance
This is the CALLED Router!!!!
