NSH-aware service function of type Virtual

One type of network service header (NSH)-aware service function (SF) that you can configure is an SF of type
Virtual
.
Before configuring NSH-aware SFs, you must create a separate virtual server to use as the SF. F5 recommends that you create dedicated/dummy VLANs for this virtual server that are separate from the other VLANs. Because this SF resides inside the service function forwarder (SFF), the SF is encapsulation-aware.
In this topology, the SF is a virtual server on the internal network.
Use this sytax to create this topology:
tmsh create ltm virtual <VS NAME > destination any:any ip-forward vlans-enabled vlans add { VLAN NAME }
tmsh create net sfc sf <SF NAME > virtual-name <VS NAME>
For example:
tmsh create ltm virtual virtual1_v4 destination any:any ip-forward vlans-enabled vlans add { virtual1 }
tmsh create net sfc sf sf_nsh_virtual virtual-name virtual1_v4
