Hi,
I did a test for CRB and IRB over isdn bri line. I found that it is successful for irb, but failed with irb. I have tried both legacy and dialer profile configuration, both are not successful. I can ping to the BVI ip address within the bridge group.
Any one has any idea?
Thanks a lot.

I seem to remember reading in the doc that irb will not work over dialup. I cannot remember exactly where, and I cannot think offhand why this should be so. Except that the bridged traffic would keep your line open most the time, and cost you a bomb.
Here it is : http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/ibm_c/bcovervw.htm#3380
"Integrated routing and bridging is supported on all media interfaces except X.25 and Integrated Services Digital Network (ISDN) bridged interfaces."
