Submit this completed document with your completed and saved packet tracer in the link provided in
Blackboard.
Part 1: Questions.
Step 1:
a. Which command displays the statistics for all interfaces configured on a router?
Show interfaces
b. Which command displays the information about the Serial 0/0/0 interface only?
Show interface serial 0/0/0
c. 1) What is the IP address configured on R1? 209.165.200.225/30
c. 2) What is the bandwidth on the Serial 0/0/0 interface? 1544 Kbits
d. 1) What is the IP address on R1? There is no ip address
d. 2) What is the MAC address of the GigabitEthernet 0/0 interface? 000d.bd6c.7d01
d. 3) What is the bandwidth on the GigabitEthernet 0/0 interface? 1000000 Kbits
Step 2. Questions.
a. Which command displays a brief summary of the current interfaces, statuses, and IP addresses
assigned to them? Show ip interface brief
b. 1) How many serial interfaces are there on R1 and R2? 2
b. 2) How many Ethernet interfaces are there on R1 and R2? 6 on R1 and 2 on R2
b. 3) Are all the Ethernet interfaces on R1 the same? If no, explain the difference(s).
No, there are 2 gigabit ethernet interfaces and 4 fast ethernet interfaces, gigabit ethernet
support speeds up to 1,000,000,000 bits and fast ethernet support speeds up to 1,000,000 bits
Step 3: Display the routing table on R1.
a. What command displays the content of the routing table? Show ip route
b. 1) How many connected routes are there (uses the C code)? 1
b. 2) Which route is listed? 209.165.200.224/30 is directly connected, Serial0/0/0
b. 3) How does a router handle a packet destined for a network that is not listed in the routing table?
A router will only send packets to a network listed in the routing table. If a network is not listed,
packet will be dropped.
Part 2 Step 3
a. What command did you use? Copy run start
Part 3 Step 1
a. 1) How many interfaces on R1 and R2 are configured with IP addresses and in the “up” and “up” state?
3 on each router
a. 2) What part of the interface configuration is NOT displayed in the command output? Subnet mask
a. 3) What commands can you use to verify this part of the configuration? show run, show interfaces,
and show ip protocols
b. 1) How many connected routes (uses the C code) do you see on each router? 3
b. 2) How many EIGRP routes (uses the D code) do you see on each router? 2
b. 3) If the router knows all the routes in the network, then the number of connected routes and
dynamically learned routes (EIGRP) should equal the total number of LANs and WANs. How many LANs
and WANs are in the topology? 5
b. 4) Does this number match the number of C and D routes shown in the routing table? yes
