these are so called,
multihoming and multiarea support.
if you configure multiple "net" s under the same "router isis [tag]",
you are basically doing multihoming, you are merging the areas,
that is you are merging the databases of the configured areas...
however with multarea support,
you configure distinct isis processes, the dbs are not merged,
which results in each isis process having
its own set of routes.
you can take advantage of this behavior,
see my previous isis post.

Subject: ISIS and multiple areas
Hello group,
I have a question on ISIS and multiple areas. I have seen practice lab
scenarios were you are asked to configure two ISIS areas on a router. I
have seen this done two different ways:
One way:
router isis
net 49.0002.2222.2222.2222.00
net 49.0003.2222.2222.2222.00
Another way:
router isis
net 49.0002.2222.2222.2222.00
router isis TEST
net 49.0003.2222.2222.2222.00
On the doc CD, they use the second method. On Doyle's book, he uses the
first method. What are the differences, and what is the preferred way? any
help would be greatly appreciated.
Thanks,
Rolando
