Runtime LMA Assignment Support for Proxy Mobile IPv6 draft-ietf-netext-recirect-03 Jouni Korhonen, Sri Gundavelli, Hidetoshi Yokota, Xiangsong Cui IETF #78, Netext WG

Recap: An enhancement to RFC5213 The I-D defines two LMA behaviors to enable a runtime LMA assignment (i.e. redirection): – “Soft” – BCE created on a target LMA during the redirection procedure. – “Hard” – BCE created on a target LMA using an additional PBU/PBA exchange after the redirection. LMA indicates to a MAG which one took place and the MAG supports both approaches. Solution can fallback to basic RFC5213 operation.

Status – Changes from 01 -> 02 Clarifications in Introduction (review Qin Wu) – Independence from DNS bullet: added a reference to draft-ietf-netlmm-lma-discovery. – Independence from AAA bullet: added a reference to RFC5777 (Diameter stuff for PMIPv6). – Anycast bullet: clarified how anycast could fit into the picture.. Section 4.2 (review Qin Wu) – Redirect mobility option has two new flags: ‘K’ & ‘N’ for indicating whether IPv6 or IPv4 r2LMA addresses are included in the option. – Clarified the use/role of ‘F’ flag when making a decision to add IPv4 r2LMA address.

Status – Changes from 02 -> 03 Introduction revisited – Anycast bullet: more text massaging how anycast could fit into the picture.. Section 4.2 – Fixed erroneous message length.. Btw - known nits in -03 (== comments): – Still using old boilerplate – At least one outdated reference – Some weird spacing (that need manual fixing)
