See the TLV discussion that Jason started. While I'm not sure he has
the right mechanism, there is definitely a requirement for hosts
to switch locators on request from a TE function as well as on outage.



I am assuming all hosts are hostile. Now what.




Understood, but do not forget inbound path selection or weighting or  
preference
or whatever you want to call it.  That needs to be controllable from  
the network

level, not from the end hosts.

Yep. I think that is also a case where hosts will need to switch
on request.



They don't.
