This example shows that NSC and NSE on the different nodes could find and work with each other using IPv6.
NSC is using the kernel
mechanism to connect to its local forwarder.
NSE is using the memif
mechanism to connect to its local forwarder.
Forwarders are using the wireguard
mechanism to connect with each other.
Deploy NSC and NSE:
kubectl apply -k https://github.com/networkservicemesh/deployments-k8s/examples/features/ipv6/Kernel2IP2Memif_ipv6?ref=c91be29099fab1f8376d9ff90c858efd829de35e
Wait for applications ready:
kubectl wait --for=condition=ready --timeout=1m pod -l app=alpine -n ns-kernel2ip2memif-ipv6
kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-memif -n ns-kernel2ip2memif-ipv6
Ping from NSC to NSE:
kubectl exec pods/alpine -n ns-kernel2ip2memif-ipv6 -- ping -c 4 2001:db8::
Ping from NSE to NSC:
result=$(kubectl exec deployments/nse-memif -n "ns-kernel2ip2memif-ipv6" -- vppctl ping 2001:db8::1 repeat 4)
echo ${result}
! echo ${result} | grep -E -q "(100% packet loss)|(0 sent)|(no egress interface)"
Delete ns:
kubectl delete ns ns-kernel2ip2memif-ipv6
