2.11 Configuration Examples

The following sections provide several examples for configuring VRRP to improve reliability.
Familiarize yourself with the configuration procedures against the networking diagram. Each
configuration example consists of the networking requirements, configuration roadmap,
configuration procedures, and configuration files.

2.11.1 Example for Configuring VRRP in Master/Backup Mode

In this example, by configuring a VRRP backup group in master/backup mode, you can use the
master device of the VRRP backup group to transmit all network traffic.
