Understanding DHCP Relay Agent Operation
A Juniper Networks device operating as a DHCP relay agent forwards incoming requests from BOOTP and DHCP clients to a specified BOOTP or DHCP server. Client requests can pass through virtual private network (VPN) tunnels.
You cannot configure a single device interface to operate as both a DHCP client and a DHCP relay.
![]() | Note: The DHCP requests received on an interface are associated to a DHCP pool that is in the same subnet as the primary IP address/subnet on an interface. If an interface is associated with multiple IP addresses/subnets, the device uses the lowest numerically assigned IP address as the primary IP address/subnet for the interface. To change the IP address/subnet that is listed as the primary address on an interface, use the set interfaces < interface name > unit 0 family inet xxx.xxx.xxx.xxx/yy primary command and commit the change. |
