Greetings, I'm using dialer profiles for DDR configuration. I can successfully setup the ISDN call and interfaces are up/up on both ends. However, I'm getting an "encapsulation failed" message when trying to ping the remote interface IP address. This is obviously the failure of the router to get a MAC address for the dialer interface. Using dialer profiles, I do not need dialer map statements. However, when I issue "sh dialer map", there are no entries indicating that dynamic map statements are not being generated. Any ideas? The caller is a 1604 running 11.2(8)P and the called is a 3640 running 12.0(8).
