Statement introduced in JUNOS Release 8.3.
traceoptions option introduced in JUNOS Release 8.5.
relay-option-60 option introduced in JUNOS Release 9.0.
Configure extended Dynamic Host Configuration Protocol (DHCP) relay options on the router and enable the router to function as a DHCP relay agent. A DHCP relay agent forwards DHCP request and reply packets between a DHCP client and a DHCP server.
The extended DHCP relay agent options configured with the dhcp-relay statement are incompatible with the DHCP/BOOTP relay agent options configured with the bootp statement. As a result, the extended DHCP relay agent and the DHCP/BOOTP relay agent cannot both be enabled on the router at the same time.
The statements are explained separately.
See Configuring the Extended DHCP Relay Agent.
