Configuring Virtual Links for OSPFv3
Virtual links can connect discontiguous sections
of the OSPF backbone Area 0 or extend backbone access to areas
not directly adjacent to Area 0 (a requirement of the OSPF protocol).
To configure a virtual link, configure the virtual-link statement at the [edit protocols ospf3 area 0] hierarchy
level. In the statement, specify the router ID of your neighbor (often
the loopback interface IP address) and the OSPFv3 area that the virtual
link travels across to reach Area 0.
