True, but I guess this is a first step.
At least, it's better than static routing. ;-)

At this time, I only have a single box (a cisco-router) acting as
'gateway' to the 6bone; but I like to add redundancy to this; so I do need
to get rid of static routes.

As my 'central point' is a cisco-router, I would need it BOTH in cisco and
on the unix-boxes.

(I could use RIP to go to a unix-box and then use zebra to continue in
OSPF; but let's not make things more difficult then necessairy. ;-)

OK. Bad idea.
Next!

If I remember correctly from the time I used this), one of the great
things about ISIS, is that you can use a single routing-protocol to carry
both OSI and IPv4 routing.

So, it would be great to use a single routing-protocol to carry both IPv4
and IPv6 routing.

Anycase, are there any implementations of ISIS on unix-boxes. (without the
v6-extensions, that is!)

Technically speaking not, but you could use it as a IGP (just assign a
private AS-number to your 'customers').

Again the same remark:
This would have the advantage to use a single routing-protocol for both
v4 and v6 routing.

Great!

Cheerio! Kr. Bonne.
