14.2 Routing with default static routes
In this section you will to take a more detailed look at static routes.
Watch the video below, which is just under 2 minutes long.
Activity 2 Think about
An extract from the routing table of Router 2 from the demonstration network in the first video is shown below.
Gateway of last resort is not set
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.10.10.0/24 is directly connected, GigabitEthernet0/0
L 10.10.10.2/32 is directly connected, GigabitEthernet0/0
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.1.0/24 is directly connected, GigabitEthernet0/1
L 172.16.1.1/32 is directly connected, GigabitEthernet0/1
Following the additional configuration to Router 1 shown in the second video, PC1 still cannot ping PC3. Can you think of any reason why this might be happening? Choose the best answer from the options below.
The default route from Router 1 to Router 2 is incorrectly configured.
There is no reverse path in Router 2’s routing table to direct the returning traffic back to Router 1.
PC3 has been configured with an incorrect IP address.
The ping typed on PC1 had the wrong IP address.
The correct answer is b.
Yes. In Router 2’s routing table, there is no known route from Router 2 to Router 1 for packets addressed to anything in the 192.168.1.0/24 network.
