Hi shariq,
I've changed the link-local address to a global address on the MN.
However, when the MN receives a RA, it creates a new link-local address.
I've tried to change the link-local addresses to global addresses on the AR and
the HA too, but radvd won't start without one, so I just added the global
addresses.
Whenever the MN changes networks, it sets the link-local address of the AR or
HA (depending on the network) as the default gateway.
Perhaps there's something wrong with the configuration of my RADVD daemons...
AR's RADVD.conf:
interface eth1
{
AdvSendAdvert on;
AdvIntervalOpt on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvHomeAgentFlag off;
prefix fec0:106:1100::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
HA's RADVD.conf:
interface ath0
{
AdvSendAdvert on;
MaxRtrAdvInterval 3;
MinRtrAdvInterval 1;
AdvIntervalOpt off;
AdvHomeAgentFlag on;
HomeAgentLifetime 10000;
HomeAgentPreference 20;
AdvHomeAgentInfo on;
prefix fec0:106:2700::2/64
{
AdvRouterAddr on;
AdvOnLink on;
AdvAutonomous on;
AdvPreferredLifetime 10000;
AdvValidLifetime 12000;
};
};
Thank you for your help,
Kris.

Hi kris,
Change the link-local address o global address. i.e.
fe80:: to 2001::
Local adresses have been phased out and that could be causing your problem.
