Description
Override the default configuration
settings for the extended DHCP relay agent. Specifying the overrides statement with no subordinate statements removes all DHCP relay
agent overrides at that hierarchy level. Use the statement at the [edit ... dhcpv6] hierarchy levels to configure DHCPv6 support.
M120 and M320 routers do not support DHCPv6.
The following statements are supported at both the [edit ... dhcp-relay] and [edit ... dhcpv6] hierarchy
levels.

dhcpv6] hierarchy levels only.

All other statements are supported at the [edit ... dhcp-relay] hierarchy levels only.
The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
