Chapter 9 Setting Up Virtual Routers
Configuring Virtual Routers
All areas in an OSPF autonomous system must be physically connected to the backbone area. In some
cases where this physical connection is not possible, you can use a vlink to connect to the backbone
through a non-backbone area. Vlinks can also be used to connect two parts of a partitioned backbone
through a non-backbone area.
