To specify the notification type (inform or trap) and target host, use the snmp-agent target-host command. Examples # Generate notifications as defined in RFC 2787 when the device in a VRRP group receives a VRRP advertisement with the authentication type or key not matching the local configuration.

The default is 48. Usage guidelines The DSCP value identifies the packet priority during transmission. A greater DSCP value means a higher packet priority.

    IMPORTANT: • You can configure different authentication modes and authentication keys for the VRRP groups on an interface. However, members of the same VRRP group must use the same authentication mode and authentication key. • For VRRPv3, this command does not take effect. Examples # Set the authentication mode to simple and the authentication key to Sysname for VRRP group 1 on VLAN-interface 2.

  • Page 73: Vrrp Vrid Priority

    To avoid frequent state changes among members in a VRRP group and to provide the backups enough time to collect information (such as routing information), a backup does not immediately become the master after it receives an advertisement with lower priority than the local priority. Instead, it waits for a period of time before taking over as the master.

  • Page 76: Vrrp Vrid Track

    Usage guidelines The master in an IPv4 VRRP group periodically sends VRRP advertisements to declare its presence. You can use this command to configure the interval at which the master sends VRRP advertisements. As a best practice, set the VRRP advertisement interval to be greater than 100 centiseconds to maintain system stability.

    In preemptive mode, a backup takes over as the master and sends VRRP advertisements when it detects that it has a higher priority than the master. The previous master then becomes a backup. This mechanism makes sure the master is always the router with the highest priority. To avoid frequent state changes among members in a VRRP group and to provide the backups enough time to collect information (such as routing information), a backup does not immediately become the master after it receives an advertisement with lower priority than the local priority.
