FTOS#
You can assign additional NET addresses, but the System ID portion of the NET address must remain the
same. FTOS supports up to six area addresses.
Some address considerations are:
• In order to be neighbors, Level 1 routers must be configured 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.
