N/A
3. Configure VF tracking.
• Configure the VF tracking
function to monitor a specified
track entry and specify the
value by which the weight
decreases:
vrrp vrid virtual-router-id weight
track track-entry-number
[ reduced weight-reduced ]
• Configure the VF tracking
function to monitor an AVF on a
specified router:
vrrp vrid virtual-router-id track
track-entry-number
forwarder-switchover
member-ip ip-address
Use either method.
The VF tracking function is not
configured by default.
Configuring VRRP packet attributes
Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a virtual
IP address for it.
Configuration guidelines
When you configure VRRP packet attributes, follow these guidelines:
• You might configure different authentication modes and authentication keys for the VRRP groups on
an interface. However, the members of the same VRRP group must use the same authentication
mode and authentication key.
• Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolong the
time interval to send VRRP advertisements.
• Configuring different intervals for sending VRRP advertisements on the routers in a VRRP group
might cause a backup to trigger a change of its status because the backup does not receive any
VRRP advertisements for a specified period of time. To solve this problem, configure the same
interval for sending VRRP advertisements on each router in the VRRP group.
