Control Description
Set Virtual Router
to Backup
Forces the master virtual router 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 initiates 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.
