configure ospf add virtual-link

configure ospf add virtual-link router-identifier area-identifier


Adds a virtual link connected to another ABR.

Syntax Description

router-identifier Specifies the router ID of the other end of the link.
area-identifier Specifies an OSPF area.



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 and cannot be a stub area or an NSSA.


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

configure ospf add virtual-link
