How To Configure Static Routes In Cisco Packet Tracer

In this lab, I am gonna teach you How to configure static routes in packet tracer

Configure Static Routes – VLSM

Given network: 200.150.100.0

Required hosts on Router 1: 14

Required hosts on Router 2: 6

R1<= 14

14<= 2ⁿ – 2

14<= 2⁴ – 2

14<= 16 – 2

14<= 14

Total number of network bits = 32

32 – n = 32 – 4 = 28 (CIDR value of given network i.e. Router 1)

i.e. 200.150.100.0/28

N.S.M = 11111111. 11111111. 11111111.11110000

                        = 255.255.255.240

Block size        = 256 – N.S.M

                        = 256 – 240 = 16

Note: Add this block size in given network so that we can get our new network for Router 2.

So the new network is 200.150.100.16/?

Now find FVH, LVH, and broadcast address

Given Network	200	150	100	0
First Valid Host-FVH	200	150	100	1
Last Valid Host-LVH	200	150	100	14
Broadcast	200	150	100	15
New Network	200	150	100	16

R2<= 6

6<= 2ⁿ – 2

6<= 2³ – 2

6<= 8 – 2

6<= 6

Total number of network bits = 32

32 – n = 32 – 3 = 29 (CIDR value of new network i.e. Router 2)

i.e. 200.150.100.16/29

N.S.M = 11111111. 11111111. 11111111.11111000

                        = 255.255.255.248

Block size        = 256 – N.S.M

                        = 256 – 248 = 8

Note: Add this block size in given network so that we can get our new network for Router 1 and 2 (Virtual Network).

So the new network is 200.150.100.24/?

Now find FVH, LVH, and broadcast address

Given Network	200	150	100	16
First Valid Host-FVH	200	150	100	17
Last Valid Host-LVH	200	150	100	22
Broadcast	200	150	100	23
New Network	200	150	100	24

Router 1 & 2 <= 2 hosts (we required only two IP to connect 2 routers)

2 <= 2ⁿ – 2

2 <= 2² – 2

2 <= 4 – 2

2 <= 2

Total number of network bits = 32

32 – n = 32 – 2 = 30 (CIDR of Virtual network (R1&R2)

i.e. 200.150.100.24/30

N.S.M = 11111111.11111111.11111111.11111100

= 255.255.255.252

Block Size        = 256 – N.S.M

= 256 – 252 = 4

Note: Add this block size in given network so that we can get our new network for Router 3. This network can be used in future.

so the new network is 200.150.100.28/?

Now find FVH, LVH and Broadcast address

Given Network	200	150	100	24
First Valid Host-FVH	200	150	100	25
Last Valid Host-LVH	200	150	100	26
Broadcast	200	150	100	27
New Network	200	150	100	28

Basic Configuration On Router 2

Basic Configuration on Router 2   Router>enable Router#configure terminal Router(config)#hostname R2 R2(config)#interface fastEthernet 0/0 R2(config-if)#ip address 200.150.100.17       255.255.255.248 R2(config-if)#no shutdown R2(config-if)#exit   R2(config)#interface serial 0/1/0 R2(config-if)#ip address 200.150.100.26       255.255.255.252 R2(config-if)#no shutdown R2(config-if)#exit R2(config)#exit R2#write

Configure Static Routes – Static Configuration On Router 1

Static Configuration on Router 1   R1>enable R1#configure terminal R1(config)#ip route 200.150.100.16              255.255.255.248         200.150.100.26 R1(config)#exit R1#write

Configure Static Routes – Static Configuration On Router 2
