14.9 CONFIGURING OSPF PARAMETERS
The RS provides several parameters that can be set at the global (router) level, at the area level, and at the interface
level. Parameters set at the interface level take precedence over those set at the area level, and parameters set at the
area level take precedence over “global” parameters. The following table lists the parameters that can be set at all three
levels.
Create a virtual
link.
ospf add virtual-link
