Chapter 14 OSPF Configuration
Confidential and Proprietary Information of ZTE CORPORATION 203
Refer to below procedure for configuration of OSPF virtual links.
Router Command Line Interface has been accessed.
OSPF is running on a network as described in above basic
OSPF configuration.
1. For virtual link configuration, use area <area-id> virtual-
link <router-id> [hello-interval <seconds>] [retransmit-
interval <seconds>] [transmit-delay <seconds>] [dead-
interval <seconds>] [authentication-key <key>] [message-
digest-key <keyid> md5 <cryptkey> [delay <time>]]
command in OSPF route mode as shown in
Table 248.

This defines an
OSPF virtual link
(if designated
area does not
exist, an area
will be created
automatically)
Result: This established a virtual link.
