Maximum Transmission Unit (MTU) issues are also presented. This draft refers to RFC1853 for IP-in-IP encapsulation which was Informational. The more useful reference would be to RFC2003, which is Standards Track. RFC2003 appears to cover most of the issues in this document, where IPsec-specific issues are further covered already in RFC2401 and its pending update. Joe
