It is not related, I modified my tunnel handler to specifically set
the /proc entries for the tunnel interface before bringing it up.
The problem seems to be that the interface does not exist when umip is
started. It's not just down, it doesn't exist at all.
Line 26 in mip6d.conf is end bracket of:
MnHomeLink "tunnel" {
HomeAddress xxxx:xxxx:0:1300::1/56;
HomeAgentAddress xxxx:xxxx::1;
}
The following is the output from mip6d:
Mobile-test:~# mip6d
Error in configuration file /etc/mip6d.conf

mip6d[3521]: Interface 1 (lo):type 772 unsupported
Nothing more happens when I start the tunnel interface and bring it up.
If I at this point restart mip6d, everything is ok.
If mip6d is started first, the tunnel interface deleted, then
recreated and brought up, mip6d does a new BU just like it should.
But starting mip6d before the interface exists does not seem to work.
