Configure an Layer 3 LAN Interface

Let us learn to configure an L3 LAN interface.
Prisma SD-WAN extends the capabilities of the Layer 3 LAN interface to include traffic forwarding. Release 5.1.1 and later enables you to use Layer 3 LAN interfaces for services such as DHCP Relay, DHCP Server, SNMP source interface, and so on. The LAN interface's enhanced Layer 3 capabilities allow for simplified topologies and help facilitate an improved branch HA model. Layer 3 LAN interface can be configured with a static or dynamic IP address and is used to forward traffic to and from the LAN. Layer 3 LAN Interface now supports static routing.
