Field Description
Router ID The router ID of this virtual neighbor (configured).

OSPF neighbor states. See the State parameter definition in table 11-12 on page 11-63. Note that
virtual neighbors should never stay in the 2WAY state.

Notice from the syntax statement that you can get OSPF virtual neighbor
