DESCRIPTION
Select an IP interface.
Select the area ID (that uses the format of an IP address in dotted decimal notation)
of an area to associate the interface to that area.
Note: OSPF Interface(s) must use the same authentication method
within the same area.
Select an authentication method. Choices are Same-as-Area, None (default),
Simple and MD5.
To participate in an OSPF network, you must set the authentication method and/or
password the same as the associated area.
Select Same-as-Area to use the same authentication method within the area and
set the related fields when necessary.
Select None to disable authentication. This is the default setting.
Select Simple and set the Key field to authenticate OSPF packets transmitted
through this interface using simple password authentication.
Select MD5 and set the Key ID and Key fields to authenticate OSPF packets
transmitted through this interface using MD5 authentication.
When you select MD5 in the Authentication field, specify the identification number of
the authentication you want to use.
When you select Simple in the Authentication field, enter a password eight-
character long. Characters after the eighth character will be ignored.
When you select MD5 in the Authentication field, enter a password 16-character
long.
The interface cost is used for calculating the routing table. Enter a number between 0
and 65535.
The priority you assign to the interface is used in router elections to decide which
router is going to be the Designated Router (DR) or the Backup Designated Router
(BDR). You can assign a number between 0 and 255. A priority of 0 means that the
router will not participate in router elections.
