E-Series Original command.
Usage 
Information
You can configure both IPv4 and IPv6 virtual addresses simultaneously, but only one of each. 
Each time this command is issued, it replaces the previously configured address of the same 
family, IPv4 or IPv6. The no virtual-ip command takes an address/prefix-length 
argument, so that the desired address only is removed. If you enter the 
no virtual-ip 
command without any specified address, then both IPv4 and IPv6 virtual addresses are 
removed.
