aka Network Stitching. This is the manual method to insert L4-7 services; VLANs, EPGs and bridge domains are manually created, and EPGs are manually assigned to the L4-7 device interfaces, statically with Static Path Binding or dynamically with a VMM domain. If we have to insert more than one L4-7 device, repeat the above process as much as there are devices to integrate.

L4-7 device vs L4-7 Device

An L4-7 device in the manual stitching context is one firewall, one ADC, etc. A L4-7 Device in Service Graphs is the Logical Device, which might contain one or more Concrete Devices.
