• On host A, specify the IP address for the host as 10.0.0.1 and configure a static route to
20.1.1.0/24 with next hop 10.0.0.2. (Details not shown.)
• On host B, specify the IP address for the host as 20.1.1.2. (Details not shown.)
Verifying the configuration
# Use the display interface tunnel command to display the status of the tunnel interfaces on Router
A and Router B. Verify that the tunnel interfaces are up. (Details not shown.)
# Verify that host A can ping host B.
