Area ID 

Enter a 32-bit ID (that uses the format of an IP address in dotted decimal

Usually interface(s) and virtual interface(s) should use the same 
authentication method as the associated area. If interface(s) and virtual 
interface(s) use different authentication methods than the associated area, 
the authentication methods are based on the interface(s) and virtual 
interface(s) settings.
