COMMAND USAGE
â—† Use the Add page to create a virtual link, and then use the Configure
Detailed Settings page to set the protocol timers and authentication
settings for the link. The parameters to be configured on the Configure
Detailed Settings page are described under "Configuring OSPF
Interfaces" on page 525.
PARAMETERS
These parameters are displayed in the web interface:
◆ Process ID – Process ID as configured in the Network Area
configuration screen (see page 504).
◆ Area ID – Identifies the transit area for the virtual link. The area ID
must be in the form of an IPv4 address, or also as a four octet unsigned
integer ranging from 0-4294967295.
◆ Neighbor – Router ID of the virtual link neighbor. This specifies the
Area Border Router (ABR) at the other end of the virtual link. To create
a virtual link, it must be configured for an ABR at both ends of the link.
One of the ABRs must be next to the isolated area and the transit area
at one end of the link, while the other ABR must be next to the transit
area and backbone at the other end of the link.

1. Click Routing Protocol, OSPF, Virtual Link.
2. Select Add from the Action list.
