|
|
|
```
|

|
|
|
|
|
|
|
```
|
|
|
|
|
$ 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
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
4. 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
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
5. Ping from sw-srv0 to sw-srv1
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ sudo ip netns exec sw-srv0 ping 10.0.0.3
|
|
|
|
|
PING 10.0.0.3 (10.0.0.3) 56(84) bytes of data.
|
|
|
|
|
64 bytes from 10.0.0.3: icmp_seq=1 ttl=63 time=0.137 ms
|
|
|
|
|
64 bytes from 10.0.0.3: icmp_seq=2 ttl=63 time=0.148 ms
