Subject: [RFC radvd 0/2] radvd: 6lowpan 6CO testing patches

Hi,

this patch is for testing 6CO fields in RA messages with the help of radvd.

I tested it with the following configuration and two or more nodes which can
directly reach each other.

On one node (6LBR, if more 6LBR they need to have the same context
information!):

interface lowpan0
{
        Adv6LBR on;
        AdvSendAdvert on;
        UnicastOnly on;
        AdvCurHopLimit 255;

        prefix 2001::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };

        lowpanco {
                ctx 0 {
                        AdvContextCompressionFlag on;
                        AdvContextLength 64;
                        AdvContextPrefix 2001::;
                        AdvLifeTime 1000;
                };
        };
};

On other nodes:

interface lowpan0
{
	Adv6LBR off;
	AdvSendAdvert off;
};

Then you can see that the assigned global link 2001::/64 address will
be compressed. Tested with: ping6 and wireshark on $WPAN interface, when
using 802.15.4 6LoWPAN.
