Test Mutually Aware NSEs

This example demonstrates mutually aware NSEs usage.

Mutually aware NSEs are allowed to have overlapping IP spaces.

Based on Policy Based Routing example.

Requires

Make sure that you have completed steps from basic or memory setup.

Run

Deploy NSC and NSE:

kubectl apply -k https://github.com/networkservicemesh/deployments-k8s/examples/features/mutually-aware-nses?ref=b5a6aa9adf11b838bc0684a0a9e17ad8690dfb52

Wait for applications ready:

kubectl wait --for=condition=ready --timeout=1m pod -l app=nsc-kernel -n ns-mutually-aware-nses

kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-kernel-1 -n ns-mutually-aware-nses

kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-kernel-2 -n ns-mutually-aware-nses

Install iproute2 on the client:

kubectl exec deployments/nsc-kernel -n ns-mutually-aware-nses -- apk update
kubectl exec deployments/nsc-kernel -n ns-mutually-aware-nses -- apk add iproute2

Check routes:

result=$(kubectl exec deployments/nsc-kernel -n ns-mutually-aware-nses -- ip r get 172.16.1.100 from 172.16.1.101 ipproto tcp dport 6666)
echo ${result}
echo ${result} | grep -E -q "172.16.1.100 from 172.16.1.101 dev nsm-1"

result=$(kubectl exec deployments/nsc-kernel -n ns-mutually-aware-nses -- ip r get 172.16.1.100 from 172.16.1.101 ipproto udp dport 5555)
echo ${result}
echo ${result} | grep -E -q "172.16.1.100 from 172.16.1.101 dev nsm-2"

Cleanup

Delete ns:

kubectl delete ns ns-mutually-aware-nses
