Hi Srikanth, Please use VPP and NSH_SFC project for running SFF, not running vxlan_tool.py.
Below is the commands used to configure your setup for running SFF, just for reference. vppctl set int state TenGigabitEthernet5/0/0 up vppctl set int ip table TenGigabitEthernet5/0/0 7 vppctl set int ip address TenGigabitEthernet5/0/0 10.10.10.3/24 vppctl ip route add 192.168.2.25/32 via 10.10.10.3 TenGigabitEthernet5/0/0 vppctl set ip arp fib-id 7 TenGigabitEthernet5/0/0 192.168.2.25 90e2.ba48.7a80 vppctl create vxlan-gpe tunnel local 10.10.10.3 remote 192.168.2.25 vni 9 next-nsh encap-vrf-id 7 decap-vrf-id 7 vppctl set int l2 bridge vxlan_gpe_tunnel0 1 1 vppctl create nsh map nsp 185 nsi 255 mapped-nsp 185 mapped-nsi 254 nsh_action swap encap-vxlan-gpe-intf 3 vppctl create nsh entry nsp 185 nsi 255 md-type 1 c1 1 c2 2 c3 3 c4 4 next-ethernet vppctl create nsh entry nsp 185 nsi 254 md-type 1 c1 11 c2 12 c3 13 c4 14 next-ethernet Yes, local 10.10.10.3 remote 192.168.2.25 is the local and peer tunnel endpoint IP.

My requirement is that, I am spawning a SFC vNF which is VPP based. So, that vNF should be IP-less NSH aware. My typical setup is as shown in the attached image. I have single Compute Node, with 2 vNFs in a Chain. One vNF is NSH aware (running vxlan_tool.py), and another vNF is VPP based VM, which is IP-less, as its interface is hooked to DPDK. As I am new to FD.io/ VPP, can you please relate the commands you sent to my setup? I may not need the entire commands...Isn't it? Anyways, In the commands you sent, I have some doubts. What are the IP's 192.168.50.71 and 192.168.50.76, those are tunnel endpoint IP's right? What is fib-id 7? Can you please filter out the particular commands to configure my setup? Regards, Srikanth.

So, vxlan_tool.py will emulate VM so that it can be NSH aware. Am I correct? Actually, I am able to run the SFC usecase with normal VM's which are NSH aware (vxlan_too.py running on the VM). Now, I am trying to run the same usecase with VPP VM as one of the SFC vNF. But, we can't run vxlan_tool.py in VPP based image as it doesn't network interfaces, as they will be hooked to DPDK. In that case, what kind of approach we need to follow? I know some work is going on ODL SFC and VPP and I am new to VPP/Fd.io. Are there any NSH aware VPP based images available? Regards, Srikanth.
