2. Multimob Routing Optimization (1/5)  http://datatracker.ietf.org/doc/draft-ietf-multimob-pmipv6-ropt/ http://datatracker.ietf.org/doc/draft-ietf-multimob-pmipv6-ropt/  Solution provides optimal access to content located either in the local (Visited) or in the remote (Home or third party) network  The MAG has the logic/rules to decide whether a multicast subscription should be made in the local network or to the remote (e.g. Home) PMIPv6 domain  Decisions can be based on subscription model, which could be pre- configured or dynamically configured by operator (e.g. draft- gundavelli-netext-pmipv6-sipto-option)  MTMA serves as mobility anchor for remote subscriptions  Typically, the MTMA will be used to get access to multicast content from Home or any third party network 2

3. Multimob Routing Optimization (2/5)  Remaining issues  [1] Document structure  [2] IPv4 support  [3] Expand details about dynamic decision to forward multicast traffic to local or remote  Suggested next steps at IETF83  Organize the document by node operation instead of by function  Provide more details about the solution to dynamically decide on local or remote access 3

4. Multimob Routing Optimization (3/5)  [1] Document structure  Intro (1)  Terminology (2)  Overview (3.1, 4.1, 6.1)  MAG operation (3.3, 4.3, 5.1, 5.2, 6.2, 6.3)  LMA operation (6.2)  MTMA operation (3.4, 6.2)  MN operation (3.2, 4.2, Considerations from RFC5213)  Data structures (5.3, Multicast group descriptor) 4

5. Multimob Routing Optimization (4/5)  [2] IPv4 Support  Add details in accordance with RFC5213 5

6. Multimob Routing Optimization (5/5)  [3] Provide more details about the solution to dynamically decide on local or remote access  For the dynamic policies, re-use PMIP signaling adding an option to carry a multicast group descriptor in the PBA message, similar to draft-gundavelli- netext-pmipv6-sipto-option  Use Multicast Address Record definition in RFC3810 as group descriptor, with some priority or mapping to home/visited (i.e. direct routing/MTMA) 6
