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.
