[AusNOG] OSPFv3 / EIGRPv4 - Link local addresses

[Beeson, Ayden]

Also idiot moment, ignore the bit about loopback, obviously that can't happen.

Thanks,

Argh, apologies for the auto-appended huge footer, they do that on our exchange server :(

Subject: [AusNOG] OSPFv3 / EIGRPv4 - Link local addresses

Hey guys,

I've got a small question and I thought somebody here might have an answer. We are implementing IPv6 internally now after bringing our external BGP up a few weeks ago, I have started configuring up OSPFv3 internally and I have instantly noticed that while it's all working fine, all the route tables show the link local addresses for each hop.

While technically this is ok, it's pretty annoying not being able to clearly see the host's actual ipv6 address on the other end of the link. I have done a bit of reading and it seems that this is the way they do their neighbour relationships now, but does anybody know if there is a way to get them to use their actual IPv6 addresses as assigned according to our IPv6 range we have been allocated?

It's not "required" per say but it's pretty annoying, at least it still shows the P2P VLAN I guess but it'd be nice for it to display an IP that actually meant something to me.

As far as I understand it, EIGRP is exactly the same so that idea went away pretty quick, thoughts?

An example entry is:
O   2405:2D00::2C/127 [110/4]
     via FE80::20E:39FF:FE17:E140, Vlan922

The host at the other end of that link has 2405:2d00::14/127 on the vlan and a loopback address of 2405:2D00::FF02/128. Ideally it would show the loopback but I'll take either over that irrelevant link local :)
