How To Configure RIP Protocol On 3 Routers In Cisco

How to configure RIP in 3 routers

In this lab, I am gonna teach you How To Configure RIP Protocol On 3 Routers In Cisco

RIP Protocol VLSM

Given Network: 192.80.10.0

1) Required hosts on Router 1= 28

2) Required hosts on Router 2= 20

3) Required hosts on Router 3= 6

How To Configure RIP Protocol On 3 Routers In Cisco

R1<= 28

28<= 2n – 2

28<= 25 – 2

28<= 32 – 2

28<= 30

Total number of network bits = 32

32 – n = 32 – 5 = 27 (CIDR value of given network i.e. Router 1)

i.e. 192.80.10.0/27

N.S.M = 11111111. 11111111. 11111111.11100000

                        = 255.255.255.224

Block Size        = 256 – N.S.M

                        = 256 – 224 = 32

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

So the new network is 192.80.10.32/?

Now find FVH, LVH and Broadcast address

Given Network19280100
First Valid Host-FVH19280101
Last Valid Host-LVH192801030
Broadcast192801031
New Network192801032

R2<= 20

20<= 2n – 2

20<= 25 – 2

20<= 32 – 2

20<= 30

Total number of network bits = 32

32 – n = 32 – 5 = 27 (CIDR value of given network i.e. Router 2)

i.e. 192.80.10.32/27

N.S.M = 11111111. 11111111. 11111111.11100000

                        = 255.255.255.224

Block Size        = 256 – N.S.M

                        = 256 – 224 = 32

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

So the new network is 192.80.10.64/?

Now find FVH, LVH and Broadcast address

Given Network192801032
First Valid Host-FVH192801033
Last Valid Host-LVH192801062
Broadcast192801063
New Network192801064

R3<= 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 given network i.e. Router 3)

i.e. 192.80.10.64/29

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 192.80.10.72/?

Now find FVH, LVH and Broadcast address

Given Network192801064
First Valid Host-FVH192801065
Last Valid Host-LVH192801070
Broadcast192801071
New Network192801072

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. 198.10.10.72/30

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 2 and 3 (Virtual Network).

so the new network is 192.80.10.76/?

Now find FVH, LVH and Broadcast address

Given Network192801072
First Valid Host-FVH192801073
Last Valid Host-LVH192801074
Broadcast192801075
New Network192801076

Router 2 & 3 <= 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 (R2&R3)

i.e. 198.10.10.76/30

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 4. This network can be used in future.

so the new network is 192.80.10.80/?

Now find FVH, LVH and Broadcast address

Given Network192801076
First Valid Host-FVH192801077
Last Valid Host-LVH192801078
Broadcast192801079
