Usage Guidelines

A virtual link provides a logical path between the ABR of the disconnected area and the ABR of the normal area that connects to the backbone. A virtual link must be established between two ABRs that have a common area, with one ABR connected to the backbone. Specify the following:

router-identifier—Far-end router interface number.
area-identifier—Transit area used for connecting the two end-points. The transit area cannot have the area identifier 0.0.0.0. and cannot be a stub area or an NSSA.

Example

The following command configures a virtual link between the two interfaces:

configure ospf add virtual-link 10.1.2.1 10.1.0.0
