Introduction:

This activity focuses on subnetting skills with VLSM, basic device configurations, static routing and RIP routing. Once you have configured all devices, you will test for end to end connectivity and examine your configuration.

Objectives

Design and document an addressing scheme based on requirements.

Apply a basic configuration to the devices.

Configure static routing between ISP routers.

Configure RIPv2 routing in Region 1 (commands provided) and static routing Region 2

Disable RIP updates on appropriate interfaces

Configure default routes and redistribute through RIP

Verify full connectivity between all devices in the topology.

Task 1: Design and document an addressing scheme.

Step 1: Design an addressing scheme.

Using the topology and the following requirements, design an addressing scheme:

The WAN links between R1 and R2 and their respective ISP routers are already configured. Also, the links between the ISPs and the Web Servers are already configured.

The address space for Region 1 is 10.1.0.0/16. Each branch router (B1-R1, B2-R1, and B3-R1) should be allotted address space based on the following requirements. Starting with the largest requirement, assign address space to each router

B1-R1 needs space for 32,000 hosts ____________________

B2-R1 needs space for 16,000 hosts ____________________

B3-R1 needs space for 8,000 hosts ____________________

Divide the address space for each branch router into four equal subnets. Record the subnets in the table below.

Router	Subnet Number	Subnet Address
B1-R1 Fa0/0	0
B1-R1 Fa0/1	1
B1-R1 Fa1/0	2
B1-R1 Fa1/1	3

Router	Subnet Number	Subnet Address
B2-R1 Fa0/0	0
B2-R1 Fa0/1	1
B2-R1 Fa1/0	2
B2-R1 Fa1/1	3

Router	Subnet Number	Subnet Address
B3-R1 Fa0/0	0
B3-R1 Fa0/1	1
B3-R1 Fa1/0	2
B3-R1 Fa1/1	3

For the WANs in Region 1, subnet the address space 10.1.255.240/28. B1-R1 to R1 uses the first subnet, B2-R1 to R1 uses the second and B3-R1 to R1 the third. Record the subnets in the table below.

Router	Subnet Number	Subnet Address
B1-R1 <--> R1	0
B2-R1 <--> R1	1
B3-R1 <--> R1	2

The address space for Region 2 is 172.20.0.0/16. Each branch router (B1-R2, B2-R2, and B3-R2) should be allotted address space based on the following requirements. Starting with the largest requirement, assign address space to each router

B1-R2 needs space for 4,000 hosts ____________________

B2-R2 needs space for 2,000 hosts ____________________

B3-R2 needs space for 1,000 hosts ____________________

Divide the address space for each branch router into four equal subnets. Record the subnets in the table below.

Router	Subnet Number	Subnet Address
B1-R2 Fa0/0	0
B1-R2 Fa0/1	1
B1-R2 Fa1/0	2
B1-R2 Fa1/1	3

Router	Subnet Number	Subnet Address
B2-R2 Fa0/0	0
B2-R2 Fa0/1	1
B2-R2 Fa1/0	2
B2-R2 Fa1/1	3

Router	Subnet Number	Subnet Address
B3-R2 Fa0/0	0
B3-R2 Fa0/1	1
B3-R2 Fa1/0	2
B3-R2 Fa1/1	3

For the WANs in Region 2, subnet the address space 172.20.255.240/28. B1-R2 to R2 uses the first subnet, B2-R2 to R2 uses the second and B3-R2 to R2 the third. Record the subnets in the table below.

Router	Subnet Number	Subnet Address
B1-R2 <--> R2	0
B2-R2 <--> R2	1
B3-R2 <--> R2	2

Step 2: Document the addressing scheme.

Document the IP addresses and subnet masks. Assign the first IP address to the router interface.

For the WAN links, assign the first IP address to R1 and R2 for links to each routers perspective B1, B2, and B3 routers.
