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.

tion for a specific area or a specific IP address.
