DHCP

Notes

There are two ways of configuring DHCP; Legacy and extended.

Both of these methods are valid. Legacy was created in an older version of Junos, while extended was updated to match across multiple platforms.

DHCP requires an active interface in the VLAN that addresses are being sent to

A juniper device can be configured as a dhcp server or a dhcp relay.
