virtual-link

Syntax

Hierarchy Level

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 of these 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.

ipsec-sa name

Apply the named IPsec authentication to the OSPF interface or virtual link or to an OSPFv2 remote sham link.

For each keychain, you must specify a name.
