LABEL

DESCRIPTION

Area ID

Type the unique, 32-bit identifier for the area in IP address format.

 

 

Type

Select the type of OSPF area.

 

Normal - This area is a normal area. It has routing information about

 

the OSPF AS and about networks outside the OSPF AS.

 

Stub - This area is an stub area. It has routing information about the

 

OSPF AS but not about networks outside the OSPF AS. It depends on a

 

default route to send information outside the OSPF AS.

 

NSSA - This area is a Not So Stubby Area (NSSA), per RFC 1587. It has

 

routing information about the OSPF AS and networks that are outside

 

the OSPF AS and are directly connected to the NSSA. It does not have

 

information about other networks outside the OSPF AS.

 

 

Authentication

Select the default authentication method used in the area. This

 

authentication protects the integrity, but not the confidentiality, of

 

routing updates.

 

None uses no authentication.

 

Text uses a plain text password that is sent over the network (not very

 

secure).

 

MD5 uses an MD5 password and authentication ID (most secure).
