3Com Router Command Reference — V1.00ViewEthernet interface viewParametervirtual_router_id: Virtual Router ID, namely, VRRP backup group number, rangingfrom 1 to 255.seconds: Interval that MASTER in backup group sends VRRP packet in seconds witha value ranging from 1 to 255. By default, the seconds is 1 second.DescriptionUsing the vrrp vrid timer-advertise command, you can configure timer of the backupgroup. Using the undo vrrp vrid timer-advertise command, you can restore thedefault value of timer.The MASTER router of a VRRP standby group notifies its normal operation state tothe routers within the group by sending them VRRP packets regularly (adver_interval).If the BACKUP routers fail to receive the VRRP packets from MASTER over a certainperiod of time (master_down_interval), they reach the conclusion that the masterrouters are not functioning properly and will change their own state to MASTER.The user can set timer adver_interval through this command, and the value of timermaster_down_interval is three time of that of adver_interval.Example# Set the interval when MASTER in backup group 1 sends VRRP packet to 5seconds.[3Com-Ethernet0]vrrp vrid 1 timer-advertise 52.1.7 vrrp vrid trackSyntaxvrrp vrid virtual_router_id track interface_type interface_number [ reduced priority ]undo vrrp vrid virtual_router_id track interface_type interface_numberViewEthernet interface view14
