The following information defines the fields reported in the show ip route command:

• The first column lists the protocol that derived the route.

• The second column may list certain protocol-specific information as defined in the display header.

• The third column lists the address of the remote network. The first number in the brackets is the administrative distance of the information source; the second number is the metric for the route.

• The fourth column specifies the address of the router that can build a route to the specified remote network.

• The fifth column specifies the last time that the route was updated, in hours:minutes:seconds.

• The final column specifies the interface through which the specified network can be reached.

Answer the following questions by using the output from the preceding show ip route command.

1 What routing protocol derived the route 130.130.0.0?

2 What router interface IP address is used to reach IP network 192.67.131.0?

3 When was the last time that the route 192.65.129.0 was updated?

4 Through which router interface can the IP network 128.128.0.0 be reached?
