Page 79: Configuring ipv4 vrrp packet attributes
71
Step Command
Remarks
69.
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 IPv4 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
•
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, increase 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. This is 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.
Configuration procedure
To configure VRRP packet attributes:
Step Command
Remarks

Configure the authentication
mode and authentication key
when the VRRP groups send
and receive VRRP packets.
vrrp vrid virtual-router-id
authentication-mode { md5 |
simple [ cipher ] } key
Optional.
Authentication is not performed by
default.
