Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Description
For backbone areas only, create a virtual link to use in place of an actual physical link. All
area border routers and other routing devices on the backbone must be contiguous. If
this is not possible and there is a break in OSPF connectivity, use virtual links to create
connectivity to the OSPF backbone. When configuring virtual links, you must configure
links on the two routing devices that form the end points of the link, and both these two
routing devices must be area border routers. You cannot configure links through stub
areas.
Options
neighbor-id router-id
—IP address of the routing device at the remote end of the virtual
link.
transit-area area-id
—Area identifier of the area through which the virtual link transits.
Virtual links are not allowed to transit the backbone area.
The remaining statements are explained separately.
Required Privilege
Level
routing—To view this statement in the configuration.
