Objectives
- Step 1: Determine IPv6 subnets and addressing scheme.
- Step 2: Configure IPv6 addressing on routers and PCs.
- Step 3: Verify IPv6 connectivity.
Background / Scenario
Network administrators must know how to implement IPv6 in their networks. You have been asked to set up a network for use by the sales staff for a customer demonstration. The network will use a series of consecutive IPv6 subnets for four LANs. Your job is to assign the subnets to the LANs and configure the routers and PCs with IPv6 addressing. Make certain to configure all the necessary components for IPv6 routing on the routers.
Instructions
Step 1: Determine IPv6 subnets and addressing scheme.
You have been given the IPv6 subnet 2001:db8:acad:00c8::/64 as the starting subnet. You will need four more subnets for each network that is required. Increment the subnet addresses consecutively by one to arrive at the four required subnets. Complete the table below.
Subnet Table
| Subnet | Address |
|---|---|
| R1 G0/0 LAN | 2001:db8:acad:00c8::0/64 |
| R1 G0/1 LAN | 2001:db8:acad:00c9::0/64 |
| R2 G0/0 LAN | 2001:db8:acad:00ca::0/64 |
| R2 G0/1 LAN | 2001:db8:acad:00cb::0/64 |
| R1 to R2 link network | 2001:db8:acad:00cc::0/64 |
Step 2: Configure IPv6 addressing on routers and PCs.
Complete the addressing table above to use as a guide for configuring the devices.
- Assign the first IP address in the subnet to the router LAN interfaces.
R1(config)# interface gigabitethernet 0/0 R1(config-if)# ipv6 address 2001:db8:acad:c8::1/64 R1(config-if)# no shutdown R1(config-if)# interface gigabitethernet 0/1 R1(config-if)# ipv6 address 2001:db8:acad:c9::1/64 R1(config-if)# no shutdown
R2(config)# interface gigabitethernet 0/0 R2(config-if)# ipv6 address 2001:db8:acad:ca::1/64 R2(config-if)# no shutdown R2(config-if)# interface gigabitethernet 0/1 R2(config-if)# ipv6 address 2001:db8:acad:cb::1/64 R2(config-if)# no shutdown
- Assign the link-local addresses as designated in the addressing table.
R1(config)# interface gigabitethernet 0/0 R1(config-if)# ipv6 address fe80::1 link-local R1(config-if)# interface gigabitethernet 0/1 R1(config-if)# ipv6 address fe80::1 link-local R1(config-if)# interface serial 0/0/0 R1(config-if)# ipv6 address fe80::1 link-local
R2(config)# interface gigabitethernet 0/0 R2(config-if)# ipv6 address fe80::2 link-local R2(config-if)# interface gigabitethernet 0/1 R2(config-if)# ipv6 address fe80::2 link-local R2(config-if)# interface serial 0/0/0 R2(config-if)# ipv6 address fe80::2 link-local
- For the connection between the routers, assign the first address in the subnet to R1.
R1(config)# interface serial 0/0/0 R1(config-if)# ipv6 address 2001:db8:acad:cc::1/64 R1(config-if)# no shutdown
- For the connection between the routers, assign the second address in the subnet to R2.
R2(config)# interface serial 0/0/0 R2(config-if)# ipv6 address 2001:db8:acad:cc::2/64 R2(config-if)# no shutdown
- Set all four hosts to automatically configure with IPv6 addresses.
R1(config)# ipv6 unicast-routing R1(config)# ipv6 route 2001:db8:acad:ca::/63 Serial0/0/0
R2(config)# ipv6 unicast-routing R2(config)# ipv6 route 2001:db8:acad:c8::/63 Serial0/0/0
Step 3: Verify IPv6 connectivity.
The PCs should be able to ping each other if addressing has been configured properly.
