Parameter
ip-address: IP relay address in dot-deliminated decimal format.
Description
Using the ip relay address command, you can specify the exact location of a DHCP
server by configuring an IP relay address for it. Using the undo ip relay address
command, you can delete one or all relay IP addresses used by an interface.
By default, no relay IP address has been configured.
Executing undo ip relay address without ip-address will delete all the relay IP
addresses configured on the current interface.
As the packets sent by DHCP client machines in some phases of DHCP are broadcast packets,
the interfaces configured with relay IP addresses must support broadcast. In other words, this
command can be used on the broadcast-supported network interfaces, Ethernet interfaces for
example.
For the related command, see dhcp select interface.
Example
Add two relay IP addresses on Ethernet 0/0/0.
