none or simple (same as for normal interface).

 

 

 

 

Interface State

 

The state of the virtual link to the virtual neighbor. The possible values are:

 

 

• DOWN – the routing switch has not yet found a route to the virtual neighbor.

 

 

• P2P – (point-to-point) the routing switch has found a route to the virtual neighbor.

 

 

Virtual links are “virtual” serial links, hence the point-to-point terminology.

 

 

 

 

 

Notice from the syntax statement that you can get OSPF virtual link informa­

 

tion for a specific area or a specific IP address.

 

Example: To get OSPF virtual link information for IP address 10.0.8.33, enter

 

the command:

 

HPswitch# show ip ospf virtual-link 10.0.8.33

 

A display similar to the following is shown.
