(usagi-users 02322) Re: Mobile IPv6

[Krishna Kumar <kumarkr@xxxxxxxxxx>]

When you start mobile-ip script as a HA, it sets
/proc/net/ipv6/conf/all/forwarding to 1 to show that it is a router.
radvd will start only if the system is a router, check /var/log/messages
for radvd exit message if forwarding==0.
So it starts when you run the HA script. Normally, router's are not allowed
to autoconfigure their addresses, that
is why radvd will not configure the system interfaces.

You can do following :
1. echo 1 > /proc/net/ipv6/conf/all/forwarding
2. radvd
Following 3 steps are for the router to configure it's own addresses :
3. echo 0 > /proc/net/ipv6/conf/all/forwarding
4. <wait for a few seconds, atleast till you get one RA, this will
configure the router's interfaces>
5. echo 1 > /proc/net/ipv6/conf/all/forwarding
6. start mobility.

So mobility is not dependent on radvd or vice-versa.

I am trying to test Mobile IPv6 by using usagi-20030331, it looks like
the HA is working and I am able to start the radvd only after I start
/etc/init.d/mobile-ip6 script. Im having problems configuring the router
so that radvd can operate.
Is it normal to start mobile-ip6 script prior to radvd.?
Do I need to configure the router as a CN and also run the mobile-ip6
script prior to running radvd?
I should mention that the kernel configuration is a combiantion of Mario
Tortonesi's "Obtaining the best IPv6 support for Linux" and the note to
set MIP6 that comes with the distribution.

THANK YOU
