11.3 Packet Processing
11.3.3 Receiving Packets While Away from Home
   While away from home, a mobile node will receive packets addressed to
   its home address, by one of three methods:
   o  Packets sent by a correspondent node that does not have a Binding
      Cache entry for the mobile node, will be tunneled to the mobile
      node via its home agent.
   o  Packets sent by a correspondent node that has a Binding Cache
      entry for the mobile node that contains the mobile node's current
      care-of address, will be sent by the correspondent node using a
      type 2 routing header.  The packet will be addressed to the mobile
      node's care-of address, with the final hop in the routing header
      directing the packet to the mobile node's home address; the
      processing of this last hop of the routing header is entirely
      internal to the mobile node, since the care-of address and home
      address are both addresses within the mobile node.
   For packets received by the first of these methods, the mobile node
   MUST check that the IPv6 source address of the tunneled packet is the
   IP address of its home agent.  In this method the mobile node SHOULD
   also send a Binding Update to the original sender of the packet, as
   described in Section 11.7.2, subject to the rate limiting defined in
   Section 11.8.  The mobile node MUST also process the received packet
   in the manner defined for IPv6 encapsulation [15], which will result
   in the encapsulated (inner) packet being processed normally by
   upper-layer protocols within the mobile node, as if it had been
   addressed (only) to the mobile node's home address.
