Configuration procedure
1) Configure IP addresses for the tunnel interfaces and related ports on the devices.
Configure IP addresses and subnet masks for related ports and the tunnel interfaces according to the
configurations shown in Figure 9-6 .
2) Configure Device A (the source device)
# Create tunnel interface Tunnel 0, and configure an IP address and subnet mask for it.
