One of the biggest reasons we made the switch is that IS-IS 
allows us to "string" our network across the globe easier 
than OSPF, because OSPF has the "all areas must connect to 
the backbone area" rule - and we don't like virtual links.

All other reasons were gravy; although we do like the fact 
that v6 is implemented in the same IS-IS protocol as v4.

This is very annoying.

We had a chat with our SE, and the DSBU are considering 
supporting IS-IS (initially for v4) on the 3560G (which we 
have a lot of) some time next year.

What kinds of issues?
