Yes. I think Multitopology is needed with IPv6 and ISIS.<br>

===============
There's another gotcha that we totally missed: MT for
IS-IS (RFC 5120) should be mentioned and it should be
MANDATORY in combination with MPLS (otherwise you might
experience some weird symptoms if you decide to run some
IPv6 natively).

Apologies for the late reply:
I think it would be a good idea to recommend MT regardless
of whether MPLS is in use or not.
Some systems, by default, will enable IS-IS for both v4 and
v6 when turned on, e.g., JUNOS. Others won't and require
either v4 or v6 support to be enabled explicitly, e.g., IOS.
I think recommending MT be supported in all implementations
of IS-IS is useful, so that native/dual-stack deployments of
v6 don't cause network outages due to lack of topology
congruency during turn-up.
Cheers,
Mark.
