Operation Manual – VRRPH3C S3610&S5510 Series Ethernet Switches Chapter 1 VRRP Configuration1-141.2.6 Configuring VRRP Packet AttributesI. Configuration prerequisitesBefore configuring the relevant attributes of VRRP packets, you should first create thestandby group and configure the virtual IP address.II. Configuration procedureFollow these steps to configure VRRP packet attributes:To do… Use the command… RemarksEnter system view system-view —Enter the specifiedinterface viewinterface interface-typeinterface-number —Configure theauthentication mode andauthentication key whenthe standby groups sendand receive VRRPpacketsvrrp vrid virtual-router-idauthentication-mode{ md5 | simple } keyOptionalAuthentication is notperformed by defaultConfigure the time intervalfor the Master in thestandby group to sendVRRP advertisementvrrp vrid virtual-router-idtimer advertiseadver-intervalOptional1 second by defaultDisable TTL check onVRRP packets vrrp un-check ttlOptionalEnabled by defaultDo not create a standbygroup before executingthis command.Note:z You may configure different authentication modes and authentication keys for thestandby groups on an interface. However, the members of the same standby groupmust use the same authentication mode and authentication key.z Factors like excessive traffic or different timer setting on switches can cause theBackup timer to time-out abnormally and trigger a change of the state. To solve thisproblem, you can prolong the time interval to send VRRP packets and configure apreemption delay.
