Hi Alper,

We were thinking of allowing the option to be carried in the PBU with 0.0.0.0/0::0 to indicate capability and also to keep it aligned with the other mobility options that we have defined recently. So, in that sense the option may be present in the PBU, but I'm wondering in what cases, the MAG would have more specific information. In general, the LMA-CP identity may be known to the MAG, but may be not the DP identity; there the broader goal is to have the DP identity be dynamically allocated by LMA-CP and have that exposed to the MAG as part of the signaling exchange.




Regards
Sri

LMA User Plane Address Mobility Option is only used with the PBA.

If the MAG has prior info about the LMA-UPA, it could also provide that in PBU.

Should we allow that new option with PBU as well?
