I'm sure the 6524 will do the biz with IS-IS like it's bigger SX/SR siblings,
and I haven't looked into it for the 4924, but the 3400 IS-IS stuff is
virtually stuck in the 1990's - No wide metrics (which is a *big* problem), no
HMAC-MD5 auth, no ISPF, no Fast Flooding, no High Priority Tag.  That's the
same situation as with old 12.1E, and in a modern network, I just don't know
how you'd make use of it at all.  I just hope it catches up and lives up to
the "S" in 12.2SE.  I'd file a feature request but I'm too demoralised.
