[Olsr-users] Next hop with link local address

[Henning Rogge]

Hi,

I assume that 1.1.1.1 and 2.2.2.2 are on the loopback device...

if yes, the 12.1 version looks correct, the "via" parameter should be
something that is on the interface.

the 11.7 variant works because Linux does strange things and answer
ARPs for IPs not on the local interface.

I would guess with IPv6 you would have got the "linklocal via" anyways
with both versions.
