The following table gives a list of known issues that await resolution for the Internet Draft draft-ietf-mobileip-rfc3012bis-04.txt ("Mobile IPv4 Challenge/Response Extensions").
The Status field marks the issues as given by the below list.
New issues can be submitted by sending an e-mail to the WG mailing list, clearly stating that there is a problem in the specification. I'll also try to create issue descriptions as the discussions go on.
