Hi Hesham/Dave/Erik, I am not taking a stand on whether an explicit off-link flag is necessary/useful or not, but I have encountered a scenario where the existing algorithm specified in RFC4861 does not work very well. Let's say a router wants to signal to the clients that 2001:dead:beef::/48 is on-link except for 2001:dead:beef:abcd::/64 that is off-link. How would it go about describing this? I see two ways
a) Advertise the /48 with L=0 and send redirects for all addresses not on the /64 b) Advertise the /48 with L=1 and the /64 with Q(the new off-link flag)=0 I see b) as being more efficient than a) P.S: I do not think that this scenario is very likely, just possible.
