IP Address Configuration (0.5 Hours)
Use the Class B IP address 130.33.0.0. Configure IP addressing as follows:
Use a 29-bit mask for VLAN 100 and a 25-bit mask for VLAN 200 and VLAN 300.
Use a 27-bit mask for VLAN 400.
Use a 24-bit mask for VLAN 500, VLAN 550, and VLAN 600.
Use a 30-bit mask for all WAN connections on Routers R1, R2, R3, and R4.
Use a 24-bit mask for the WAN connection between Routers R4/R5 and R4/R6.
After IP routing is completed, all interfaces should be pingable from any router.
Table 9-1 displays the IP address assignment for Routers R1–R6.
