Runtime LMA Assignment Support for Proxy Mobile IPv6 draft-ietf-netext-recirect-00 Jouni Korhonen, Sri Gundavelli, Hidetoshi Yokota, Xiangsong Cui IETF #76, Netext WG

Status Update WG item now – draft-korhonen-netext-redirect-04 -> draft-ietf- netext-redirect-00 – Almost meeting to the charter schedule ;)

Solution Enhancements 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.

Recent Discussion on the List.. Whether the runtime LMA assignment applies: – Only to the initial PBU/PBA exchange, or – Any PBU/PBA exchange, which would allow midsession LMA assignment e.g. during handovers. Applicability of dynamic SA creation in case of runtime LMA assignment. – Currently the I-D says the MAY for dynamic creation of SAs whereas RFC5213 says SHOULD. Status values in case of runtime LMA selection gets rejected or successfully takes place.
