You must configure all virtual routers in the VRRP group with the same settings. Configure all routers with preempt enabled or configure all with preempt disabled. 1. Create a virtual router for the interface with the VRRP identifier in INTERFACE mode, from 1 to 255. vrrp-group vrrp-id 2. Prevent any backup router with a higher priority from becoming the Master router in INTERFACE-VRRP mode. no preempt Disable preempt OS10(config)# interface ethernet 1/1/5 OS10(conf-if-eth1/1/5)# vrrp-group 254 OS10(conf-eth1/1/5-vrid-254)# no preempt View running configuration OS10(conf-eth1/1/5-vrid-254)# do show running-configuration !

Advertisement interval By default, the master router transmits a VRRP advertisement to all members of the VRRP group every one second, indicating it is operational and is the master router. If the VRRP group misses three consecutive advertisements, the election process begins and the backup virtual router with the highest priority transitions to master. To avoid throttling VRRP advertisement packets, Dell EMC recommends increasing the VRRP advertisement interval to a value higher than the default value of one second. If you change the time interval between VRRP advertisements on one router, change it on all participating routers. If you configure VRRP version 2, you must configure the timer values in multiple of whole seconds. For example, a timer value of 3 seconds or 300 centisecs is valid and equivalent. A time value of 50 centisecs is invalid because it not a multiple of 1 second. If you are using VRRP version 3, you must configure the timer values in multiples of 25 centisecs. A centisecs is 1/100 of a second. ● Create a virtual router for the interface with the VRRP identifier in INTERFACE mode, from 1 to 255. vrrp-group vrrp-id ● For VRRPv2, change the advertisement interval setting in seconds in INTERFACE-VRRP mode, from 1 to 255, default 1. advertise-interval seconds ● For VRRPv3, change the advertisement centisecs interval setting INTERFACE-VRRP mode, from 25 to 4075, default 100. advertise-interval centisecs centisecs Layer 3 819

You must configure all virtual routers in the VRRP group with the same settings. Configure all routers with preempt enabled or

configure all with preempt disabled.

Create a virtual router for the interface with the VRRP identifier in INTERFACE mode, from 1 to 255.

vrrp-group

vrrp-id

Prevent any backup router with a higher priority from becoming the Master router in INTERFACE-VRRP mode.

Advertisement interval

By default, the master router transmits a VRRP advertisement to all members of the VRRP group every one second, indicating it

is operational and is the master router.

If the VRRP group misses three consecutive advertisements, the election process begins and the backup virtual router with the

highest priority transitions to master. To avoid throttling VRRP advertisement packets, Dell EMC recommends increasing the

VRRP advertisement interval to a value higher than the default value of one second. If you change the time interval between

VRRP advertisements on one router, change it on all participating routers.

If you configure VRRP version 2, you must configure the timer values in multiple of whole seconds. For example, a timer value of

3 seconds or 300 centisecs is valid and equivalent. A time value of 50 centisecs is invalid because it not a multiple of 1 second. If

you are using VRRP version 3, you must configure the timer values in multiples of 25 centisecs. A centisecs is 1/100 of a second.
