[support] Problem in using racoon in the live CD

[Sebastien Decugis]

Hello,

I think this is normal. mip6d will add your home address to some 
interface, but the automatic address is handled by the kernel when you 
receive RA.

If you want to disable this, the you can tweak the behavior through 
/proc/sys/net/ipv6/conf/... but for mip6d to work properly you must be 
able to receive RA.

Why this BA was received? It seems it trigs the core dump, but it also 
looks it is invalid, is it?
Can you do the same test with disabling the Route Optimization feature?

Unfortunately I don't have the ability to reproduce your problem for now.

Hope this helps,
Sebastien.
