Integrated IS-IS Configuration Commands 599
■
key: Specifies the authentication key on an interface. It is a character string not
exceeding 16 characters. This value must equal the authentication key of the
virtually linked neighbor. And the key will be displayed in a cipher text form in a
length of 24 characters when display current-configuration command is
executed. Inputting the key in a cipher text form with 24 characters long is also
supported.
Description
Using the vlink-peer command, you can create and configure a virtual link. Using
the 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
somewhat can be regarded as a common ospf enabled interface so that you can
easily understand how 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 command, see authentication-mode, and display ospf.
Example
Create a virtual link to 10.110.0.3 and use the MD5 cipher text authentication
mode.
[3Com-ospf] area 10.0.0.0
[3Com-ospf-area-10.0.0.0] vlink-peer 10.110.0.3 md5 3 345
