OSPFv3 and stub interfaces without lladdr

[Christian Tacke]

Hi,

I am trying to get ipv6 routes to openvpn server into ospf.

if have an
	interface "tun*" { stub; };
in my bird6.conf.

openvpn does not add link level addrs to its interfaces. 
That's why ospf ignores this interface.  Ignoring it for
doing ospf on it is okay, as ospf really wants to run over
lladdrs.  But do stub networks require a lladdr to be used
in ospf?  This is at least confusing to me.

bird> sh int
tun2 up (index=20)
	PtP Multicast AdminUp LinkUp MTU=1500
	fdxx:xxxx:xxxx:4000::1/64 (Primary, scope site)
bird> show ospf interface "tun2"
ospf1:

A workaround is to add fe80::1/64 to tun2 in some "up"
script in openvpn, so that bird6 sees the interface. But
that does not feel right, really.

Cheers

Christian
