Assign Subnet 7 to the link between : ____________ h. Assign Subnet 8 to the link between : ____________ i. Assign Subnet 9 to the link between : _____________ j. Assign Subnet 10 to the link between: _____________ k. Assign Subnet 11 to the link between: _____________ Step 3: Document the addressing scheme. Complete the Addressing Table using the following guidelines: a. Assign the first usable IP addresses to routers for each of the L A N links. b. Use the following method to assign W A N link IP addresses: · For the WAN link between R 1 and R 2 , assign the first usable IP address to R 1 and last usable IP address R 2. · For the W A N link between R 2 and R 3 , assign the first usable IP address to R 2 and last usable IP address R 3 . · For the W A N link between R 3 and R 4 , assign the first usable IP address to R 3 and last usable IP address R 4 . c. Assign the second usable IP addresses to the switches. d. Assign the last usable IP addresses to the hosts.

Implement the following steps to complete the addressing configuration. Step 1: Configure IP addressing on R1 and R2 LAN interfaces. Step 2: Configure IP addressing on S3, including the default gateway. Step 3: Configure IP addressing on PC4, including the default gateway. Step 4: Verify connectivity. You can only verify connectivity from R 1 , R 2 , S 3 , and P C 4 . However, you should be able to ping every IP address listed in the A d d re s s in g T a b le.
