Lab 6.1.2 Creating a Network Diagram From Routing Tables

Step 1:Examine the routing table entries for the router R1

a. Examine show ip route output from router R1 shown below

b. How many networks does router R1 know about? Jawaban : Lima networks

c. How many networks are directly connected to this router? Jawaban : Tiga networks

d. How many networks have been learned from another router? Jawaban : Dua network

e. Using the codes at the beginning of the show ip route output what does the ‘R’ mean?Jawaban : R adalah router

f. In the routers learned via RIP to which device does the ip address 172.17.0.2 belong?Jawaban : Ya ada

g. In the routers learned via RIP to which device is serial 0/0 referring and what does it mean? Jawaban : 0/0 adalah interfacenya yaitu menampilkan informasi khusus hardware interface. Perintah ini harus di-set termasuk nomor port/slot dari interface serial.

Step 2: Examine the routing table entries for the router R2

a. Examine show ip route output from router R2 shown below

b. How many networks does router R2 know about? Jawaban : Lima networks

c. How many networks are directly connected to this router? Jawaban : Tiga networks

d. How many networks have been learned from another router? Jawaban : Dua networks

e. Using the codes at the beginning of the show ip route output what does the ‘R’ mean?Jawaban : R adalah router

f. In the routers learned via RIP to which device does the ip address 172.17.0.2 belong?Jawaban : Ya ada

g. In the routers learned via RIP to which device is serial 0/0 referring and what does it mean? Jawaban : Serial 0/0 adalah interface –nya yaitu menampilkan informasi khusus hardware interface. Perintah ini harus di-set termasuk nomor port/slot dari interface serial.

Step 3: document router interfaces and IP addresses

a. Based on the shown ip router output from R1 and R2

Device	interface	IP Address	Subnet mask (dotted decimal and/xx)
R1	0/0	172.17.0.0	255.255.0.0/16
R1	0/0	192.168.1.0	255.255.255.0/24
R1	0/1	192.168.2.0	255.255.255.0/24
R2	0/0	172.17.0.0	255.255.0.0/16
R2	0/0	192.168.3.0	255.255.255.0/24
R2		192.168.4.0	255.255.255.0/24

b. In this example can the exact IP address of all router interface be determined by looking at the routing tables? Ya bisa

c. Which router interface IP address can be determined from the routing tables? Interface 0/0 dan 0/1

Step 4: create a network topology diagram

Step 5: reflection

a. What do you think would happen to the entries in the routing table on R1 if one of the enthernet networks on R2 was disconnected? Jawaban : Maka pemrosesan sinyal untuk data jaringan computer akan terputus atau tidak akan terjadi.

b. What do you think would happen to the entries in the routing tables on R1 and R2 if the serial interface on R2 was shut down?
