HOWTO Use Virtual Switch
- Create a docker with 32 front panel port
$ docker run -id --name sw debian bash
$ sudo ./create_vnet.sh sw
$ ip netns list

- Start sonic virtual switch docker
$ docker run --privileged --network container:sw -d docker-sonic-vs
- Setup IP in the virtual switch docker
$ docker exec -it vs bash
root@2e9b5c2dc2a2:/# ifconfig Ethernet0 10.0.0.0/31 up
root@2e9b5c2dc2a2:/# ifconfig Ethernet4 10.0.0.2/31 up
- Setup IP in the server network namespace
$ sudo ip netns exec sw-srv0 ifconfig eth0 10.0.0.1/31
$ sudo ip netns exec sw-srv0 ip route add default via 10.0.0.0
$ sudo ip netns exec sw-srv1 ifconfig eth0 10.0.0.3/31
$ sudo ip netns exec sw-srv1 ip route add default via 10.0.0.2
- Ping from sw-srv0 to sw-srv1
$ sudo ip netns exec sw-srv0 ping 10.0.0.3
