Disable preempt
Prevent the Backup router with the higher priority from becoming the master router by disabling the preemption process. The preempt
command is enabled by default. The command forces the system to change the master router if another router with a higher priority
comes online.
You must congure all virtual routers in the VRRP group with the same settings. Congure all routers with preempt enabled or congure all
with preempt disabled.
1 Create a virtual router for the interface with the VRRP identier in INTERFACE mode (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
3 Save the conguration.
