Hi,
 
I'd like to know how GRE tunnels are setup in MIP.  In particular, 
how is the GRE key and protocol type conveyed from the FA to the HA?  
Is the same key used in both directions?  
 
There's an expired draft describing this at
http://www.alternic.org/drafts/drafts-c-d/draft-calhoun-mobileip-gre-ext-00.html
Are these extensions supported by any vendor?
 
Appreciate any pointers,
 
Thanks,
 
senthil.
