[radvd-devel-l] New IP added to interface associated with radvd

[Ben Greear]

I have a strange problem, and not sure if radvd is to blame or not.

I assign an IP to a device:

    inet6 2002:67::2/64 scope global
        valid_lft forever preferred_lft forever

and then start radvd with this config file:

interface rddVR3
{
    AdvSendAdvert on;
    IgnoreIfMissing on;
    MinRtrAdvInterval 30;
    MaxRtrAdvInterval 100;
    prefix 2002:67::2/64
    {
       AdvOnLink on;
       AdvAutonomous on;
       AdvRouterAddr on;
    };
};


A minute or so later, the peer interface gets what appears to be a proper
IP.

But, the rddVR3 interface is also given a new IP:

19: rddVR3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
     link/ether aa:cf:47:e9:1d:b4 brd ff:ff:ff:ff:ff:ff
     inet6 2002:67::a8cf:47ff:fee9:1db4/64 scope global dynamic
        valid_lft 86252sec preferred_lft 14252sec
     inet6 2002:67::2/64 scope global
        valid_lft forever preferred_lft forever
     inet6 fe80::a8cf:47ff:fee9:1db4/64 scope link
        valid_lft forever preferred_lft forever


Is this something that is expected to happen?

Thanks,
Ben
