Hi Carl and Zhou,

I think this is interesting work clarifying how to make the mobile
router work in PMIPv6 domain. I, however, have a couple of comments on
this I-D:

(1) In Section 3.3.1, at step 1, a PMIPv6 tunnel is established before
PBU/PBA at steps 3 and 4. On the other hand, after steps 3 and 4, no
PMIPv6 tunnel appears to be established. In this specification, two
PBU/PBA exchanges happen or only once?

(2) In Section 3.4.1,

  "In order to support this specification, the conceptual Binding Cache
   entry data structure needs to be extended..."

I think it's "Binding Update List entry" not "Binding Cache entry" here

(3) In Section 3.5.2, it is said,

     "In order to receive those packets, the
      mobile access gateway MUST advertise a connected route into the
      Routing Infrastructure for the mobile router's mobile network
      prefix(es)"

I think it's the local mobility anchor not the mobile access gateway to
do this in this context.

Hope my comments will help improve the document.

Regards,
