Purpose

In this lab, we used Cisco Packet Tracer to configure IPv6 in a workspace so that Champlain College and Middlebury College hosts can ping each other successfully.

---

Prefixes

The following prefixes were used to assign for each network.

Network	Prefix
Champlain College	2620:E4:C000::/64
Middlebury College	2001:1890:139D::/64
VTEL ISP (connects Champlain and Middlebury)	1800:2200:185::/64

Configuring the Champlain Router

To start, we configured the Champlain router by first assigning a general prefix for its internal network.

Then, we configured the port of FastEthernet0/1 with an IP address based on the named general prefix.

Lastly, because IPv6 is not enabled by default due to Cisco not routing IPv6 traffic between directly connected interfaces as with IPv4, we needed to enable this.

---

Configuring the Champlain Host Using SLACC

Next, we configured the Champlain host using SLACC, a service that auto-assigns an IP address based on the local router's prefix and the host's MAC address.

In Desktop > IP Configuration on Champlain Host, set the IPv6 configuration to Automatic. This should result in an IPv6 address being assigned automatically based on the Champlain prefix.

Pinging the host at 2620:e4:c000::1 should also succeed.

---

Configuring the Middlebury Router

Next, we configured the Middlebury router in a similar manner to that of the Champlain router.

The process was largely the same except for using the Middlebury prefix and configuring it accordingly.

---

Configuring the Middlebury Host Using SLACC

Similar steps were performed to obtain an IPv6 configuration and verify connectivity on the Middlebury host.

---

Configuring the VTEL ISP Router

With the two internal networks configured, we next configured the external connections associated with them on the VTEL ISP router.

IPv6 routing was first enabled on the router.

Then, we assigned an IP address to the port of FastEthernet0/0 through use of the "eui" shortcut, which sets the prefix and uses that MAC address for the host portion; like the auto-config process for the host interfaces but here is used on the router itself. The VTEL ISP prefix was used for this configuration.

The command show ipv6 interface brief outside of config mode should show that the IPv6 address has been assigned.

---

Configuring ISP on the Champlain and Middlebury Routers

Next, we configured ISP on the Champlain and Middlebury routers to get IPv6 addresses.

Rerun the show ipv6 interface brief command to verify that the IPv6 addresses have been assigned on both routers.

---

Configuring IPv6 RIP

On all of the routers, RIP was enabled with a process number so the routes could be broadcasted.

Running the command show ipv6 route outside of config mode should show all of the networks on each of the routers.

---

Connectivity Testing

If everything was configured successfully, it should be possible to ping between the Champlain and Middlebury hosts via the command prompt.
