8.
Enter the router ID of the neighbor router.
9.
Modify the default settings of the following parameters if needed: hello interval, transit delay, retransmit
interval and, dead interval.
NOTE:
For a description of all virtual link parameters and their possible values, see “Modify Virtual Link
Parameters” on page 17-24.
10. Click Add to save the change to the device’s running-config file.
11. Select the Save link at the bottom of the dialog, then select Yes when prompted to save the configuration
change to the startup-config file on the device’s flash memory.
12. Log onto the neighbor router and configure the other end of the virtual link.
Modify Virtual Link Parameters
OSPF has some parameters that you can modify for virtual links. Notice that these are the same parameters as
the ones you can modify for physical interfaces.
USING THE CLI
You can modify default values for virtual links using the following CLI command at the
OSPF router level
of the
CLI, as shown in the following syntax:
Syntax:
area <num> | <ip-addr> virtual-link <ip-addr> [authentication-key [0 | 1] <string>] [dead-interval <num>]
[hello-interval <num>] [md5-authentication key-activation-wait-time <num> | key-id <num> [0 | 1] key <string>]
[retransmit-interval <num>] [transmit-delay <num>]
The parameters are described below. For syntax information, see the
Foundry Switch and Router Command Line
Interface Reference
.
USING THE WEB MANAGEMENT INTERFACE
To modify virtual link default values:
1.
Log on to the device using a valid user name and password for read-write access.
2.
Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
3.
Click on the plus sign next to OSPF in the tree view to expand the list of OSPF option links.
4.
Click on the Virtual Link link to display a table listing the virtual links.
5.
Click on the Modify button to the right of the row describing the virtual link you want to modify. The OSPF
Virtual Link Interface configuration panel is displayed.
6.
Modify the parameters as needed. (See the following section for descriptions of the parameters.)
7.
Click Add to save the change to the device’s running-config file.
8.
Select the Save link at the bottom of the dialog, then select Yes when prompted to save the configuration
change to the startup-config file on the device’s flash memory.
9.
Log on to the neighbor router and configure parameter changes to match those configured for the local router.
Virtual Link Parameter Descriptions
You can modify the following virtual link interface parameters:
Authentication Key
:
This
parameter
allows you to assign different authentication methods on a port-by-port
basis. OSPF supports three methods of authentication for each interface—none, simple password, and MD5.
Only one method of authentication can be active on an interface at a time.
The
simple password method of authentication requires you to configure an alphanumeric password on an
interface. The password can be up to eight characters long. The simple password setting takes effect
immediately. All OSPF packets transmitted on the interface contain this password. All OSPF packets received on
the interface are checked for this password. If the password is not present, then the packet is dropped.
