back - Set virtual router to backup
Table 7-4 Operations-Level VRRP Menu Options (/oper/vrrp)
Command Syntax and Usage
back <virtual router number (1-1024)>
Forces the specified master virtual router on this switch into backup mode. This is generally used
for passing master control back to a preferred switch once the preferred switch has been returned to
service after a failure. When this command is executed, the current master gives up control and ini-
tiates a new election by temporarily advertising its own priority level as 0 (lowest). After the new
election, the virtual router forced into backup mode by this command will resume master control in
the following cases:
This switch owns the virtual router (the IP addresses of the virtual router and its IP interface are
the same)
This switch’s virtual router has a higher priority and preemption is enabled.
There are no other virtual routers available to take master control.
