Switch 7700 Command reference Guide, v2.0

Integrated IS-IS Configuration Commands 161
retransmit seconds Enter the interval for the retransmission of LSA packets on
an interface, in the range 1 to 8192 seconds. The default value is 5 seconds.
trans-delay seconds Enter the delay interval for transmitting LSA packets on an
interface, in the range 1 to 8192 seconds. The default value is 1 second.
dead seconds Enter the dead time interval, in the range 1 to 8192 seconds. This
value must equal the dead time of the virtually linked router, and must be at least
four times that of the hello interval. The default value is 40 seconds.
simple password Enter the simple text authentication key of the interface, in no
more than eight characters. This must equal the authentication key of the virtually
linked neighbor.
md5 keyid Enter the MD5 authentication key ID, in the range 1 to 255. This must
be equal to the authentication key ID of the virtually linked peer.
key Enter the MD5 authentication key, in a character string not exceeding 16
characters. This must be equal to the authentication key of the virtually linked
peer. It is displayed in cipher text format, 24 characters in length. Entering the key
in cipher text format with 24 characters 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.
RFC2328 recommends that an OSPF area should be connected to the backbone
network. You can use
vlink-peer command to set up 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.
When configuring virtual link authentication, use the authentication-mode
command to set the authentication type to MD5 cipher text or plain text on the
backbone network.
Related commands: authentication-mode, display ospf.
Example
To create a virtual link to 10.110.0.3, and use the MD5 cipher authentication
mode, enter the following:
[SW7700-ospf]area 10.0.0.0
[SW7700-ospf-area-10.0.0.0]vlink-peer 10.110.0.3 md5 3 345

Commands
This section describes the commands you can use to configure Integrated
Intermediate System-to-Intermediate System (IS-IS) on your Switch 7700.
When an Ethernet switch runs a routing protocol, it can perform the router
functions. Router that is referred to in the following and its icon represent a
generalized router or an Ethernet switch running routing protocols. To improve
readability, this will not be described in the other parts of the manual.
