Layer 3 Routing Commands 1487
This command replaces the bootpdhcprelay enable command, but affects not
only relay of DHCP packets, but also relay of any other protocols for which an
IP helper address has been configured.
When in Virtual Router Configuration mode, this command operates within
the context of the virtual router instance. When in Global Configuration
mode, the command operates on the global router instance.
Virtual Router Configuration mode is only available on the N3000-
ON/N3100-ON/N3200-ON switches.
Example
console(config)#ip helper enable
show ip helper-address
Use the show ip helper-address command to display the IP helper address
configuration.
