should maintain the connectivity with the backbone area and the backbone area should maintain
its own connectivity. In actual applications, this requirement may not be met because of some
restrictions. To solve this problem, you can configure OSPFv3 virtual links.
A virtual link must be configured at both ends of the link; otherwise, it does not take effect.
