Subject: [Mipshop] [issue13] redundant tunnels in FMIPv6?

New submission from Brahim Gaabab <[email-masked]>:

When no nCoA is delivered in an FBA received at the pAR link, FMIPv6 operation
results in two tunnels : pAR-nAR after the end of the first HI/HAck, and
pAR-nCoA after the 'successful' FBU/FBA at nAR link.

Here we have unecessarily established the second tunnel (pAR-nCoA). Two
possibilities to deal with this:
 1. PAR and NAR delete the pAR-nAR tunnel (and corresponding host routes) after
the second 'succesful' HI/HAck 
 2. MN do not engage in the second FBU/FBA (after handover)
