If R2 is only receiving the ISDN call, does it really need a dialer map
statement? I have had plenty of success with dynamic dialer maps. (but they
were all on a PRI...)

No dialer map on the far end. You should see an encap fail on the called
router. It has no idea how to reach 10.1.1.1.
Your options are to ad a dialer map string on R2 in the fashion of
dialer map ip 10.1.1.1 555XXX
This will force the use of two BRI channels, one for traffic in each
direction. Unidirectional flow on each channel between routers.
The other option is to use authentication to map the remote back. If you use
authentication then you could use a dialer map statement like such:
dialer map ip 10.1.1.1 name r1
Now the router know where to send the traffic without firing up a
connection. This would allow you to use a single channel for bi-directional
traffic.
Check your debugs. My opinion is that Cisco has superior products because of
the breadth of information available in the debugs. If it is not working it
will tell you why.
If I could only get them to tell me why in the lab it would be a different
story.
This is a common Layer 2 to Layer 3 mapping issue.

Folks,
I am not able to figure this one out:
Cannot ping to 10.1.1.2 from R1, sh dialer and all link
layer stuff is up.
Thanks,
R1
