Hi Teco,

Thanks for your comments and your patience in waiting for me to get back to you.

B1c Semi-hierarchical locators are administratively or automatically assigned. Local reconnection during link state changes is accomplished with rerouting instead of renumbering.


Sure.


Only major criticisms 3.3.2.3. #1 applies to B1c, and I have problems with the wording.
Was:
   1.  This strategy is probably not compatible with UDP or TCP though
       B1a/c could be compatible with IPv6's layer 3.  The replacement
       layer-4/5 protocols should also be coaxable to run on top of
       IPv4's layer 3 in the not-yet-upgraded part of the network.

I see no reason why it is not compatible. It must be for obvious reasons.


The problem is that the locator would still be part of the pseudo-header. How do you do the checksum calculation if the locator selection happens after the packet leaves the transport layer and is to be transmitted?
