Firewalls running PAN-OS 10.1 and SD-WAN Plugin
2.1.0 support SD-WAN on Layer 3 subinterfaces so that the firewall
can segment traffic using VLAN tags. The following task shows how
to create a Layer3 subinterface that uses a static IP address and
how to create one that uses DHCP to get its address. It shows how
to assign a VLAN tag to the subinterface and enable SD-WAN on the
subinterface. Create an SD-WAN interface profile to define each
ISP connection and assign the profile to the corresponding subinterface
(a virtual SD-WAN interface).
If you configure SD-WAN
Layer 3 subinterfaces on VM-Series firewalls, the VMware configuration
must have respective portgroups attached to those interfaces that
allow all VLANs.
