well, bleeding edge fearures in ISIS would also depend on your vendor...
ours seems backwards for ISIS in most of their product line and
we're always wanting more.... heck, I think they've even tried to ensure its not in
their training courses either...just the briefest of mentions  :/

as for IGP -   ISIS - we moved to it from OSPF because we didnt want
2 seperate routing calculations and tables being kept for IPv4 and IPv6 and
all routing config is under the one routing protocol.
