I need help with Part A. Let me know if you have any further questions.

Here we will use the same network configuration as in Problem 2. Three networks - Network A, Network B, and Network C -- are connected to each other with one router between Network A and Network B, and another router between Network B and Network C. The MAC and IPv4 addresses of each network adapter are configured as illustrated in the following figure. When you are asked to create routing table rules, make sure to specify the Network Destination, Netmask, Gateway, and Interface fields, and explain why each field's value has been chosen in your answer. You do not need to include the Metric field, since metric specifics can only be determined with knowledge of the specifics of a computer's environment. You may use the titles given in the figure for the network adapter specifications in the routing table. Part A- Computer A's Routing Table Configuration Subpart I) Calculate the network address and subnet mask of all three networks. You will need these values to create rules for the computer's routing table. Subpart II) Create a routing table for Computer A that has no default route, and that supports sending packets to all hosts (directly or indirectly) on Network A, Network B, and Network C. A hint is that this routing table will contain three rules. Subpart III) Create a routing table for Computer A that has a default route, and that supports sending packets to all hosts (directly or indirectly) on Network A, Network B, and Network C. Subpart IV) In this scenario, would you recommend using the routing table in Subpart II, or the routing table in Subpart III? Explain why. Part B - Router BC's Routing Table Configuration Create a routing table for Router BC which has no default route, which supports communications to all hosts (directly or indirectly) on Network A, Network B, and Network C. A hint is that the routing table will contain three rules.

Explanation / Answer

Subpart 1 ) For Network A Network Address is 75.126.216.0/22 & Subnet Mask is 255.255.252.0 , For Network B Network Address is 69.172.200.0/23 & Subnet Mask is 255.255.254.0, For Network C Network Address is 171.223.4.0/24 & Subnet Mask is 255.255.255.0

Subpart 2) To ping Network A to Network B and Network C we can use RIP routing protocol. First Give IP in router serial and fast ethernet port IP for three seperate router as shown in picture. Router to computer connection will be made through fast ethernet port and router to router connection will made through serial interface.

Router AB>enable
Router AB # configure terminal
Router AB(config)#interface fastEthernet 0/0
Router AB(config-if)#no shutdown
Router AB(config-if)#ip address 75.126.216.1 255.255.252.0
Router AB(config-if)#exit
Router AB(config)#interface fastEthernet 1/0
Router AB(config-if)#ip address 69.172.200.1 255.255.254.0
Router AB(config-if)#no shutdown

Router BC>enable
Router BC # configure terminal
Router BC(config)#interface fastEthernet 0/0
Router BC(config-if)#no shutdown
Router BC(config-if)#ip address 69.172.201.1 255.255.254.0
Router BC(config-if)#exit
Router BC(config)#interface fastEthernet 1/0
Router BC(config-if)#ip address 172.223.4.1 255.255.255.0

Router BC(config)#interface fastEthernet 1/1
Router BC(config-if)#ip address 172.223.4.33 255.255.255.0
Router BC(config-if)#no shutdown

Put below configuration in Router AB

Router AB(Config) # router rip

Router AB(Config-Router) # network 75.126.216.0

Router AB(Config-Router) # network 69.172.200.0

Put Below Configuration in Router BC

Router BC(Config)# router rip

Router BC(Config- Router)# network 69.172.200.0

Router BC(Config-Router) # network 171.223.4.0

Subpart 3

To generate default route

Router AB(Config) # router rip

Router AB(Config-Router) #default-information originate

Router BC(Config) # router rip

Router BC(Config-Router) #default-information originate

Subpart 4

I will prefer solution provided in subpart because it will minimize the possibilities of error in routing table
