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.

Interface/object tracking
You can monitor the state of any interface according to the virtual group. OS10 supports a maximum of 10 track groups and
each track group can track only one interface.
