keyid: Specify the MD5 authentication key ID. Its value ranges from 1 to 255. It must be
equal to the authentication key ID of the virtually linked peer.
key: Specify the MD5 authentication key. If it is input in a plain text form, the key is a
character string not exceeding 16 characters. And it will be displayed in a cipher text
form in a length of 24 characters when display current-configuration command is
executed. Inputting the MD5 key in a cipher text form with 24 characters is also
supported.
Description
Using vlink-peer command, you can create and configure a virtual link. Using undo
vlink-peer command, you can cancel an existing virtual link.
According to RFC2328, the OSPF area should be connected with the backbone
network. You can use vlink-peer command to keep the connectivity. Virtual link can be
regarded as a common interface that uses OSPF so that you can easily understand
why to configure the parameters such as hello, retransmit, and trans-delay on it.
One thing should be mentioned. When configuring virtual link authentication,
authentication-mode command is used to set the authentication mode as MD5 cipher
text or simple text on the backbone network.
For the related commands, see authentication-mode, display ospf.
Example
# Create a virtual link to 10.110.0.3 and use the MD5 cipher authentication mode.
[Quidway-ospf] area 10.0.0.0
[Quidway-ospf-area-10.0.0.0] vlink-peer 10.110.0.3 md5 3 345
