Hi Leaf, > Section 3 - If the DHCP server to which the DHCP Request message was sent > at time T1 has not responded, the DHCP client enters the REBINDING state > and attempts to contact any server. > Per the Figure 5 in RFC2131, the above 'T1' sounds 'T2'. (http://www.rfc-editor.org/rfc/rfc2131.txt) Why T2? According to section 4.4.5 of RFC 2131: " At time T1 the client moves to RENEWING state and sends (via unicast) a DHCPREQUEST message to the server to extend its lease." [..] " If no DHCPACK arrives before time T2, the client moves to REBINDING state and sends (via broadcast) a DHCPREQUEST message to extend its lease." The DHCPREQUEST is sent at T1, in my opinion the current text is correct.

In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract IPv6 Rapid Deployment (6rd) is one of the most popular methods to provide both IPv4 and IPv6 connectivity services simultaneously during the IPv4/IPv6 co-existing period. The Dynamic Host Configuration Protocol (DHCP) 6rd option has been defined to configure 6rd Customer Edge (CE). However, in many networks, the configuration information may be stored in Authentication Authorization and Accounting (AAA) servers while user configuration is mainly from Broadband Network Gateway (BNG) through DHCP protocol. This document defines a Remote Authentication Dial In User Service (RADIUS) attribute that carries 6rd configuration information from AAA server to BNG. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-softwire-6rd-radius-attrib/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-softwire-6rd-radius-attrib/ballot / No IPR declarations have been submitted directly on this I-D. _______________________________________________ Softwires mailing list Softwires@xxxxxxxx https://www.ietf.org/mailman/listinfo/softwires _______________________________________________ Softwires mailing list Softwires@xxxxxxxx https://www.ietf.org/mailman/listinfo/softwires Questo messaggio e i suoi allegati sono indirizzati esclusivamente alle persone indicate.
