Subject: /128 link-local subnet on 6in4 (sit) tunnels?
Date: Tue, 26 Mar 2013 23:04:17 +0100	[thread overview]
Message-ID: <1364335457.8215.21.camel@localhost> (raw)

Hi,

I was trying to get OSPFv3 working on NBMA 6in4 tunnel on linux 3.8, but
it does not work. I noticed it uses a /128 fe80 link-local subnet
instead of the rfc4213[1]-mandated /64.. This breaks bird (likely for
other reasons), but also interoperability with cisco, which mandates
OSPFv3 NBMA on link-local addresses.

So I was wondering, is there any particular reason for the use of a /128
link-local or is this just a bug?

Regards,

Wilco Baan Hofman
