Authentication
Note: Virtual interfaces must use the same authentication method within the same
area.
Select an authentication method. The choices are Same-as-Area, None (default), Simple
and MD5.
To exchange OSPF packets with a peer border router, you must make the authentication
method and/or password settings the same as the peer border router.
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 to authenticate OSPF packets transmitted through this interface using a simple
password.
Select MD5 to authenticate OSPF packets transmitted through this interface using MD5
authentication.
Key ID When you select MD5 in the Authentication field, specify the identification number of the
authentication you want to use.
Key When you select Simple in the Authentication field, enter a password eight-character long.
When you select MD5 in the Authentication field, enter a password 16-character long.
Retransmit
Interval
Specify how long (in seconds) the Switch should wait for an acknowledgment packet from the
interface's neighbor device before retransmitting link-state advertisements (LSAs) on the
interface. The valid range for retransmitting is between 1 and 65535. The default value is 5
seconds.
Transmit Delay Set the estimated time (in seconds) that is required to transmit a link-state update packet on
the interface. The valid range for transmitting delay is between 1 and 65535. The default value
is 1 second.
Hello Interval Specify how often (in seconds) the Switch sends hello packets on the interface to check if the
interface's neighbor devices still exist. The valid range for hello interval is between 1 and 65535.
The default value is 10 seconds.
Dead Interval Specify how long (in seconds) the Switch should wait for a hello packet from the interface's
neighbor device before declaring that the neighbor device is not available. The valid range for
dead interval is between 1 and 65535. The default value is 40 seconds.
Add Click Add to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
Clear Click Clear to set the above fields back to the factory defaults.
Index This field displays an index number of an entry.
Name This field displays a descriptive name of a virtual link.
Peer Router ID This field displays the ID (that uses the format of an IP address in dotted decimal notation) of a
peer border router.
Authentication This field displays the authentication method used (Same-as-Area, None,
Simple or MD5).
Key ID When the Authentication field displays MD5, this field displays the identification number of the
key used.
Select an entry’s check box to select a specific entry. Otherwise, select the check box in the
table heading row to select all entries.
Delete Click Delete to remove the selected entry from the summary table.
Cancel Click Cancel to clear the Delete check boxes.
