Hi Bob,
Will a router with two separate ISIS processes automatically redistribute L1
routes?
I have always used the multiple net statements to support separate ISIS
areas, so I'm unclear about this point. The document you posted seems to
suggest that L1 routers on a single router belonging to two separate ISIS
process will automatically redistribute. Is this correct?

"Redistribution- IP routes learned via Level 1 routing are advertised by
default into Level 2. Even when multiple Level 1 processes are configured on
the same unit, this fact is still true. No additional configuration is
required to redistribute all Level 1 IP routes into the Level 2 process. "

Dehong,
If you are required to have differet interfaces on the same router in
different ISIS areas, then I would suggest two different ISIS processes.
This is the approach suggested by Cisco in the link below. When you
configure multiple NETs under one process, your database will show a single,
merged area.

Subject: ISIS mutiple area question..
> I have another question for the group. If you are asked to configure
multiple areas, say 2, under one router, should you configure two net
statements under one router isis or two seperate net statements under
different router isis? or it doesn't matter? My thought is two router isis
statements, but I did see case 1 as well, so I would like to clarify it with
the group..
