Command Syntax and Usage
back <virtual router number>
 
Forces all primary virtual routers on this Alteon into backup mode. This is generally used for passing primary control back to a preferred Alteon once the preferred Alteon has been returned to service after a failure.
When back is executed, the current primary gives up control and initiates a new election by temporarily advertising its own priority level as 0 (lowest). After the new election, the virtual routers forced into backup mode resume primary control in the following cases:
*This Alteon owns the virtual router (the IP addresses of the virtual router and its IP interface are the same).
*This Alteon’s virtual router has a higher priority and preemption is enabled.
*There are no other virtual routers available to take primary control.
Note: This option is available only if the vADC is running in a hot-standby configuration.
