C 192.168.1.0/24 is directly connected, Serial0/0/1
C 192.168.2.0/24 is directly connected, FastEthernet0/0
What networks are present in the topology diagram but not in the routing table for R3?
172.16.1.0/24, 172.16.2.0/24, 172.16.3.0/24
Why are all the networks not in the routing tables for each of the routers?
The routers are not configured with static or dynamic routing. Therefore, routers only
know about the directly connected networks.
What can be added to the network so that devices that are not directly connected can ping
each other?
Static routes.
Task 8: Configure a Static Route Using a Next-Hop Address
To configure static routes with a next-hop address specified, use the following syntax:
Step 1.
Router(config)# ip route network-address subnet-mask ip-address
where:
network-address indicates the destination network address of the remote network to be
added to the routing table.
subnet-mask indicates the subnet mask of the remote network to be added to the rout-
ing table. The subnet mask can be modified to summarize a group of networks.
ip-address indicates what is commonly referred to as the next-hop router's IP address.
On the R3 router, configure a static route to the 172.16.1.0 network using the Serial 0/0/1
interface of R2 as the next-hop address.
R3(config)# ip route 172.16.1.0 255.255.255.0 192.168.1.2
R3(config)#
