There are 2 network interfaces:

a) eth0 which is a DHCP address so that a connection can be made from the host computer (your laptop). In this case the IP is 10.0.0.21

b) eth1 which is a fixed IP address. This is used to connect between the source and target servers. This IP is 10.1.1.11

6. Restart the VM (dbv02)

No Format
shutdown -r now

...

There is only one network interface:

eth2 which is a fixed IP address. This is used to connect between the source and target servers and also to the Internet. This IP is 10.0.2.5.

9. Test if the network connection is working. Use Control-C to stop the ping.
