Figure 8- 34. OSPF Virtual Link Settings - Edit
Configure the following parameters if you are adding or changing an OSPF Virtual Interface:
Parameter Description
Transit Area ID
Allows the entry of an OSPF Area ID − previously defined on the Switch − that allows
a remote area to communicate with the backbone (area 0). A Transit Area cannot be a
Stub Area or a Backbone Area.
Neighbor Router
The OSPF router ID for the remote router. This is a 32-bit number in the form of an IP
address (xxx.xxx.xxx.xxx) that uniquely identifies the remote area’s Area Border
Router.
Hello Interval (1-
65535)
Specify the interval between the transmission of OSPF Hello packets, in seconds.
Enter a value between 1 and 65535 seconds. The Hello Interval, Dead Interval,
Authorization Type, and Authorization Key should have identical settings for all
routers on the same network.
Dead Interval (1-
65535)
Specify the length of time between (receiving) Hello packets from a neighbor router
before the selected area declares that router down. Again, all routers on the network
should use the same setting.
Auth Type
If using authorization for OSPF routers, select the type being used. MD5 key
authorization must be set up in the MD5 Key Settings menu.
Password/Auth. Key
ID
Enter a case-sensitive password for simple authorization or enter the MD5 key you set
in the MD5 Key settings menu.
Transmit Delay
The number of seconds required to transmit a link state update over this virtual link.
Transit delay takes into account transmission and propagation delays. This field is
fixed at 1 second.
RetransInterval
The number of seconds between link state advertisement retransmissions for
adjacencies belonging to this virtual link. This field is fixed at 5 seconds.
