CCNA LAB Practice - Assign the IP Address on the Serial Interfaces of the Router.

II. Assign the IP Address on the Serial Interfaces of the Router.

Diagram

Procedure

1)      Check for the interfaces summary of the Router R1 & R2

2)      Check for the DCE & DTE interfaces of the Router R1 & R2

3)      Assign the IP Address on the Serial Interfaces of the Router R1 & R2.

4)      Display the interface information of the Serial interface of the Router R1 & R2.

5)      Verify the connectivity of the Router R1 & R2.

Configuration         

Step 1: Check for the Interfaces summary of the Routers.

R1#show ip interface brief

Interface              IP-Address       OK? Method     Status                              Protocol

Ethernet0           unassigned      YES NVRAM  administratively down down

Serial0                unassigned      YES NVRAM  administratively down down

Serial1                unassigned      YES NVRAM  administratively down down

Step 2(A): Check for the DCE cable of the Router R1.

R1#show controllers serial 0

HD unit 0, idb = 0x10DB04, driver structure at 0x1139D8

buffer size 1524  HD unit 0, RS-232 DCE cable

cpb = 0x22, eda = 0x4140, cda = 0x4000

<Output Omitted>

0 missed datagrams, 0 overruns

0 bad datagram encapsulations, 0 memory errors

0 transmitter underruns

0 residual bit errors

Step 2(B): Check for the DTE cable of the Router R2.

R2#show controllers serial 0

HD unit 0, idb = 0x160118, driver structure at 0x165478

buffer size 1524  HD unit 0, RS-232 DTE cable

cpb = 0x22, eda = 0x412C, cda = 0x4140

<Output Omitted>

0 missed datagrams, 0 overruns

0 bad datagram encapsulations, 0 memory errors

0 transmitter underruns

0 residual bit errors

Step 3(A): Assign the IP Address on the Serial Interface of the Router R1.

R1(config)#interface serial 0

R1(config-if)#ip address 15.0.0.1 255.0.0.0

R1(config-if)#no shutdown

R1(config-if)#clock rate 64000   (Clock Rate will set only DCE Interface)

R1(config-if)#end

Step 3(A): Assign the IP Address on the Serial Interface of the Router R2.

R2(config)#interface serial 0

R2(config-if)#ip address 15.0.0.2 255.0.0.0

R2(config-if)#no shutdown

R2(config-if)#end

Step 4: Display the interface information of the Serial interface of the Router.

R1#show interfaces serial 0

Serial0 is up, line protocol is up

  Hardware is HD64570

  Internet address is 15.0.0.1/8

  MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation HDLC, loopback not set

  Keepalive set (10 sec)

  Last input 00:00:04, output 00:00:00, output hang never

  Last clearing of "show interface" counters 01:48:12

  Queueing strategy: fifo

  Output queue 0/40, 0 drops; input queue 0/75, 0 drops

<Output Omitted>

Step 5(A): Check for the Interfaces summary of the Router R1.

R1#show ip interface brief

Interface              IP-Address       OK?    Method     Status                              Protocol

Ethernet0            unassigned        YES   unset         administratively down    down

Serial0               15.0.0.1             YES   manual     up                                    up

Serial1                unassigned        YES   NVRAM  administratively down    down

Step 5(B): Verify the connectivity of the Router R1 & R2.

R1#ping 15.0.0.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 15.0.0.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/32 ms
