Parameters
area-id
Specifies the identifier of the area to establish the virtual link.
router-id
Specifies the Router ID of the virtual link neighbor.
authentication
(Optional) Specifies authentication type. If the authentication type is not specified for
the virtual-link, the simple password authentication type for the area will be used.
message-digest
(Optional) Specifies that MD5 authentication is used for the virtual link.
null
(Optional) Specifies that no authentication is used.
hello-interval
seconds
(Optional) Specifies the interval in seconds that the router sends the hello packet on
the virtual link. The valid setting is 1-65535.
dead-interval
seconds
(Optional) Specifies the interval in seconds that a neighbor is regarded as off-line if
no hello packets are received within that time. The valid setting is 1-65535.
authentication-key
password
(Optional) Specifies up to 8 bytes long password used for simple password
authentication.
message-digest-key
key-
id
md5
key
(Optional) Specifies up to 16 bytes long digest key for MD5 authentication. The
range of
key-id
is 1-255.

Usage Guideline
In the OSPF routing domain, all areas must be connected with the backbone area. If
an area disconnects from the backbone area, it requires establish a virtual link to
connect the backbone area. Otherwise, the network communication will become
abnormal.
The virtual link requires a connection between two ABR. The area that belongs to
both ABR is called the transition area. A stub Area or NSSA area cannot act as a
transition area.
The virtual link is a point to point link. The router will send the OSPF message to the
neighbor router via unicast IP packet.
The simple text authentication type and MD5 authentication type are mutually
exclusive.
The Dead interval must be larger than and multiple as Hello interval.
Users can verify the settings by entering the
show ip ospf
or
show ip ospf virtual-
link
command.
Example
This example shows how to configure a virtual link with neighbor 3.3.3.3 and set the
authentication type to simple password with password “yourpass”.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#router ospf
DXS-3600-32S(config-router)#area 0.0.0.1
DXS-3600-32S(config-router)#area 0.0.0.1 virtual-link 3.3.3.3 dead-interval 10 hello-interval 5
DXS-3600-32S(config-router)#area 0.0.0.1 virtual-link 3.3.3.3 authentication authentication-key
yourpass
DXS-3600-32S(config-router)#
Example
This example shows how to set this virtual link’s authentication type to MD5.
DXS-3600-32S(config-router)#area 0.0.0.1 virtual-link 4.4.4.4 authentication message-digest
message-digest-key 1 md5 1234567812345678
DXS-3600-32S(config-router)#
