ipv6 ospf virtual-link OSPFv3 Commands
page 18-12 OmniSwitch CLI Reference Guide March 2011
Usage Guidelines
•
Use the no form of the command to delete the virtual link.
•
You can define areas in such a way that the backbone is no longer contiguous. In this case, the system
administrator can ensure backbone connectivity physically.
•
Virtual links can be configured between any two backbone routers that have an interface to a common
non-backbone area. Virtual links belong to the backbone. The protocol treats two routers joined by a
virtual link as if they were connected by an unnumbered point-to-point network. The routing protocol
traffic that flows along the virtual link uses intra-area routing only.
•
If authentication is enabled, both routers at either end of the virtual link must share the same password.
Simple authentication refers to the use of only clear-text passwords as an authentication method. MD5
authentication refers to the usage of message digests.
•
The dead-interval value should be the same for all the routers on the same network. This value should
be a multiple of the value provided for the hello-interval .
