MTU must match due to the padding that ISIS does to max MTU size. The
question (as I interpreted it) had to do with a Cat3550 sitting in the
middle of two routers. The Cat's MTU size being equal to or greater than
the routers would make no difference. As long as the routers match, life is
good.
Otherwise, the Cat 3550 doesn't run ISIS as far as I know. :)

Ollie,
The link below suggests that mtu must match and provides a workaround using
the clns mtu command -
