Using Hot Standby Together with Other Features

The configuration of most features of the FW in hot standby networking is the same as that in single-node networking. Currently, there are special requirements for features, such as IPSec, NAT, and virtual systems, when they are used together with hot standby. Before configuration, understand the requirements and the configuration methods on the web UI and CLI.

Configuring Interworking Between BFD/IP-Link and Hot Standby: By configuring interworking between hot standby and BFD/IP-link, VGMP groups can monitor remote interface faults to ensure link reliability.

Configuring Interworking Between Hot Standby and Dynamic Routes: By configuring interworking between hot standby and dynamic routes, VGMP groups can monitor routing neighbor faults to ensure link reliability.

Configuring NAT Hot Standby: This section describes how to use NAT in hot standby networking. For example, in load balancing mode where two devices participate in traffic forwarding, how to solve the problem of port and IP address conflicts?

Configuring Hot Standby of Virtual Systems: Different from that in the single-node networking, implementing the virtual system function in the hot standby networking has special requirements. Before configuring hot standby in virtual systems, you need to understand the implementation principles, configuration requirements, and configuration methods of hot standby in virtual systems.

Configuring IPSec Hot Standby: This section describes how to use IPSec in the hot standby networking. For example, how to ensure that IPSec services are not affected after an active/standby switchover.

Configuring IPv6 Hot Standby: Different from IPv4, deploying IPv6 functions in hot standby networking has certain special requirements. Before configuring IPv6 hot standby, learn its differences from IPv4 hot standby and its configuration method.
