I'm trying to setup dialin ISDN routing from a Ascend P75 to a Cisco 4000
My 4000 is configured for IP unnumber on the BRI that the P75 will call
into, it also is configured for no peer default IP address.
The P75 calls and authenticates with the 4000 fine, but pings from both
routers, and hosts on the network fail.
Any help or suggestions would be appreciated.
