Usage
guidelines
The DHCP provides a mechanism to transmit the configuration
information to the host in the TCP/IP network. The DHCP message
has a variable option field that can be defined according to the actual
requirement. The DHCP client needs to carry the DHCP message
with 32 bytes of option information at least. Furthermore, the fixed
data field in the DHCP message is also referred to as an option. For
the definition of current DHCP option, refer to RFC 2131.
Examples
The configuration example below defines the option code 19, which
determines whether the DHCP client can enable the IP packet
forwarding. 0 indicates to disable the IP packet forwarding, and 1
indicates to enable the IP packet forwarding. The configuration below
enable the IP packet forwarding on the DHCP client.
Ruijie(dhcp-config)# option 19 hex 1
The configuration example below defines the option code 33, which
provides the DHCP client with the static route information. The DHCP
client will install two static routes: 1) the destination network
172.16.12.0 and the gateway 192.168.12.12, 2) the destination network
172.16.16.0 and the gateway 192.168.12.16.
