To disable preemption on a Backup, enter commands such as the following.
Router1(config)# interface ethernet 1/6
Router1(config-if-e10000-1/6)# ip vrrp vrid 1
Router1(config-if-e10000-1/6-vrid-1)# non-preempt-mode
Syntax: non-preempt-mode
The syntax is the same for VRRP and VRRPE.
Master router abdication and reinstatement
To change the Master’s priority, enter commands such as the following.
BigIron RX(config)# ip interface ethernet 1/6
BigIron RX(config-if-e10000-1/6)# ip vrrp vrid 1
BigIron RX(config-if-e10000-1/6-vrid-1)# owner priority 99
Syntax: [no] owner priority | track-priority <num>
The <num> parameter specifies the new priority and can be a number from 1 – 254.
When you press Enter, the software changes the priority of the Master to the specified priority. If
the new priority is lower than at least one Backup’s priority for the same virtual router, the Backup
takes over and becomes the new Master until the next software reload or system reset.
To verify the change, enter the following command from any level of the CLI.
BigIron RX(config-if-e10000-1/6-vrid-1)# show ip vrrp
Total number of VRRP routers defined: 1
Interface ethernet 1/6
auth-type no authentication
VRID 1
state backup
administrative-status enabled
mode owner
priority 99
current priority 99
hello-interval 1 sec
ip-address 192.53.5.1
backup routers 192.53.5.2
This example shows that even though this BigIron RX is the Owner of the virtual router (“mode
owner”), the BigIron RX’s priority for the virtual router is only 99 and the state is now “backup”
instead of “active”. In addition, the administrative status is “enabled”.
To change the Master’s priority back to the default Owner priority 255, enter “no” followed by the
command you entered to change the priority. For example, to change the priority of a VRRP Owner
back to 255 from 99, enter the following command.
BigIron RX(config-if-e10000-1/6-vrid-1)# no owner priority 99
You cannot set the priority to 255 using the owner priority command.
