A.When labels are allocated manually, ensure that the outgoing label of an upstream node is the same as the incoming label of the downstream node.

C.LSPs created by static Distribution labels can be dynamically adjusted according to network topology changes, without the need for administrator intervention.

A.A pre-authentication domain defines public network resources that users can access before passing identity authentication in the area, for example, the DNS server, external authentication source, Service Manager, and Service Controller.

B.A post-authentication domain defines controlled network resources that end users can access after passing identity authentication and security check, for example, the ERP system, financial system, and database.

C.Authentication domains are classified into the pre-authentication domain, isolation domain, and post-authentication domain.

D.An isolation domain defines resources that end users passing identity authentication but failing the security check can access. These resources such as the patch server and antivirus server can help end users eliminate violations.
