This section provides configuration examples of multi-device
backup. Each configuration example consists of information such as
the networking requirements, configuration precautions, and configuration
roadmap.
This section provides an example for configuring Redundancy User Information (RUI)+enhanced dynamic service gateway (EDSG) in exclusive address pool mode.
This section provides an example for configuring Redundancy User Information (RUI)+enhanced dynamic service gateway (EDSG) in shared address pool mode.
This section provides an example for configuring dual-device hot backup for Layer 3 static IPv4 users and a networking diagram for understanding usage scenarios and configuration procedures.
This section provides an example for configuring user access (web+MAC authentication) in a dual-device hot backup scenario, so that users can access the network again without re-entering usernames and passwords within a specified period after their first login.
In a dual-device hot backup scenario, dual-stack users connect to the master and backup BRASs using IPoE. The BRASs assign IPv6 addresses to the users in ND unshared+PD mode to implement user access.
In a dual-device hot backup scenario, dual-stack home users connect to the master and backup BRASs using PPPoE. The BRASs assign IPv6 addresses to the users in ND unshared+PD mode to implement user access.
