WebOSPF is a standard based Link-State routing protocol. It is a Classless routing protocol which do not send subnet masks with updates. So, it allows to use VLSM. Open Shortest Path First has similarities with the other Link-State routing protocol IS-IS but it differents from it in many points. WebFor such a scenario, we can build an ospf virtual link. With virtual links the routing updates will be tunneled. So it logically spans a transit area, but the data is sent natively.
