Task 4: Identify Routing Processes
Examine the R1 routing table.
Step 1.
What are the IP addresses of the directly connected neighbors of the R1 router?
10.10.10.4
10.10.10.8
172.16.1.0/27
172.16.3.0/25
192.168.1.0/24
Which routes did R1 learn from the directly connected neighbors?
10.10.10.0
10.10.10.12
172.16.1.32/28
172.16.1.192/26
172.16.2.0/26
172.16.2.64/27
172.16.3.128/26
172.16.3.192/29
172.16.4.0/27
172.16.4.128/25
Examine the R2 routing table.
Step 2.
How many total networks/subnets did R2 learn from its neighbors?
13
Where would R2 send packets to networks not currently in its routing table? Why?
The packets would be sent to the R3 router at the IP address 10.10.10.2. This is the IP
address that is the default route in the R2 routing table.
What does the statement
R* 0.0.0.0/0 [120/2] via 10.10.10.2, 00:00:04, Serial0/0/0
at
the end of the R2 routing table represent?
Default route to 10.10.10.2
Examine the R3 routing table.
Step 3.
Which level 2 routes did R3 learn about from its neighbors?
10.10.10.8
10.10.10.12
172.16.1.0/27
172.16.1.32/28
172.16.2.0/26
