You can assign more NET addresses, but the System ID portion of the NET address must remain the same.
The system supports up to six area addresses.
Some address considerations are:
• In order to be neighbors, configure Level 1 routers with at least one common area address.
• A Level 2 router becomes a neighbor with another Level 2 router regardless of the area address
configured. However, if the area addresses are different, the link between the Level 2 routers is only at
Level 2.
