Description
Configure Dynamic Host Configuration Protocol (DHCP) local server options on the router or switch to enable the router or switch to function as an extended DHCP local server. The DHCP local server receives DHCP request and reply packets from DHCP clients and then responds with an IP address and other optional configuration information to the client.
The extended DHCP local server is incompatible with the DHCP
server on J Series routers and, therefore, is not supported on J Series
routers. Also, the DHCP local server and the DHCP/BOOTP relay server,
which are configured under the [edit forwarding-options helpers] hierarchy level, cannot both be enabled on the router or switch
at the same time. The extended DHCP local server is fully compatible
with the extended DHCP relay feature.
The dhcpv6 stanza configures the router or switch
to support Dynamic Host Configuration Protocol for IPv6 (DHCPv6).
The DHCPv6 local server is fully compatible with the extended DHCP
local server and the extended DHCP relay feature.
Note:
When you configure the dhcp-local-server statement at the routing instance hierarchy level, you must use
a routing instance type of virtual-router.
The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
