Comment: "A mobile access gateway when sending a Proxy Binding Update
message
   can request the local mobility anchor to assign a group identifier
   for the mobile node's mobility session."

   You might want to clarify that this is done for an MN which is
   performing initial attachment and for which there does not exist any
   mobility session yet.

Comment: " Any time the local mobility anchor detects that the mobile node
      has roamed and changed its point of attachment to a new mobile
      access gateway, it SHOULD also update the group identifier of the
      mobility session. "

      If the LMA detects that an MN has attached to a different MAG it
      MUST delete the entry from the previous group. And subsequently
      update the GID if one has been assigned as a result of
      attachment to the new MAG.

The security section does not address the threats arising from the
ability to perform bulk operations. Suggest further enhancing the
security considerations section to include concerns about bulk
operations.
