+# VPP IP Forwader Pipeline Service Chain (from the CNF Testbed)
+
+Upstream: https://github.com/cncf/cnf-testbed/tree/master/examples/use_case/3c2n-csp
+
+Description:  Pipeline Service Chain using  3 chains of 2 CNFs (per chain)
+
+This example installs the pipeline service chain example on a kubernetes worker node. All nodes are connected using Memif interfaces, with the chain endpoints connecting to the host vSwitch (VPP) while the intermediate connections are done directly between nodes.
+
+Description:
+- Layer 3 packet forwarding
+- Based on the fd.io VPP project
+- Uses DPDK
+- memif interfaces
+
+# Prerequistes
+### Install helm version 3
+
+### Automated installation
+Run cnf-conformance setup 
+```
+export KUBECONFIG=$(pwd)/<YourKubeConf> ; crystal src/cnf-conformance.cr setup
+```
+
+Setup and deploy  service chain
+```
+export KUBECONFIG=$(pwd)/admin.conf ; crystal src/cnf-conformance.cr example_cnf_setup example-cnf-path=example-cnfs/vpp-3c2n-csp-use-case
+```
+
+### Testing
+Run the conformance suite: `export KUBECONFIG=$(pwd)/admin.conf ; crystal src/cnf-conformance.cr all`
+
+### Automated cleanup
+```
+export KUBECONFIG=$(pwd)/admin.conf ; crystal src/cnf-conformance.cr example_cnf_cleanup example-cnf-path=example-cnfs/vpp-3c2n-csp-use-case
+```
+
+### Manual installation
+1. Install helm version 3
+1. Make the cnfs/vpp-3c2n-csp-use-case diretory 
+1. If you are testing the cnf source, clone the source into the cnfs/vpp-3c2n-csp-use-case directory
+1. Copy the cnf-conformance.yml into the cnfs/vpp-3c2n-csp-use-case directory
+1. Deploy the service chain using helm: `helm install vpp-3c2n-csp-use-case cnfs/csp`
+1. Wait for the installation to finish (all pods are ready)
+1. Run the conformance suite: `export KUBECONFIG=$(pwd)/admin.conf ; crystal src/cnf-conformance.cr all`
