6.7.2 Configuring the Interval for Sending VRRP Advertising
Messages
By prolonging the interval for sending VRRP advertisement packets on a virtual switch, you
can reduce the network load.
Issue 01 (2011-07-15)
By increasing the interval for sending VRRP advertisement packets by the backup group,
you can reduce the network load caused by negotiation packets.
Configurations of intervals for sending VRRP packets affect the master router election
differently in VRRP for IPv4 and VRRP6 as follows:
– In VRRP for IPv4, the members in a VRRP backup group are configured with the same
interval for sending VRRP packets, which prevents multiple backup routers from being
switched to master routers simultaneously in one VRRP backup group.
– In VRRP6, only can one master router work in a VRRP6 backup group in spite of the
fact that members are configured with different intervals for sending VRRP packets.
By configuring the preemption mode and preemption delay time of the switch in the backup
group, you can increase or reduce the speed of the master/backup switchover.
By enabling the test on the reachability of the virtual IP address, you can ping the virtual
IP address to check the network connectivity.
By prohibiting the system from checking number of hops in VRRP packets, you can
improve the compatibility of Huawei routers with different vendors' routers.
