Lab 11-1 IPv6 PT Lab

For this lab, we will be working with the scenario below:

Goal:

Successfully ping between an IPv6 host at Champlain and an IPv6 Host at Middlebury

Guidelines:

2620:E4:C000::/64 assigned prefix to Champlain College

2001:1890:139D::/64 assigned prefix to Middlebury College

1800:2200:185::/64 is the network used by the ISP, VTEL, to connect Champlain and Middlebury.

Step I: Configure the Champlain College Router

To Do:

Assign a General Prefix for the internal Champlain network

• From config mode: "ipv6 general-prefix champ-pre ipv6_prefix_for_champlain"
• In the above command,"champ-pre" can be any word, it basically names the prefix so you can refer to it later
• The "ipv6_prefix_for_champlain" is in the format x:x:x:x::/64 using the address assigned above

Configure FastEthernet 0/1 with an IP address using the named general prefix

• config interface fastethernet0/1
• We can assign an ip using the named prefix so we do not need to re-type
• e.x: "ipv6 address 2620:E4:C000::1/64"
• This will give the interface the ip v6 address 2620:e4:c000:0:0:0:0:1 or 2620:e4:c000::1

Enable IPv6 local routing

• Cisco will not route IPv6 between directly connected interfaces by default - like it does with IPv4
• use command "ipv6 unicast-routing" from global config mode

Make sure FastEthernet 0/1 is not shutdown

Step II: config Champlain Host using SLAAC

SLAAC is a service that host can use to auto-assign an IP address based on the local routers prefix and the hosts MAC address

On Champlain Host- Desktop-IP configuration: Click Auto-Config under IPv6 Configration

You should see the IP address populate starting with 2620:e4:c000......

From the Desktop Command Prompt: ping 2620:e4:c000::1 and it should succeed

Step III: Repeat Steps I and II for Middlebury

Perform the same steps for Middlebury but make sure to update the IPv6 networks/prefixes for Middlebury

Step IV: Configure VTEL Router

Enable ipv6 unicast-routing as you did with Champlain and Middlebury

Assign an IP address to F0/0 using the "eui" shortcut. This essentially sets the prefix and then uses that MAC address for the host portion. This is similar to auto-config but is used on the router itself

• e.x: On interface FastEthernet 0/0: ipv6 address x.x.x.x::/64 eui-64 where x's are the VTEL prefix

Make sure interface is not shutdown

Exit config mode and run "show ipv6 interface brief" to see that an IPv6 address is assigned

Step V: Configure Middlebury and Champlain router ISP interfaces to get IPv6 addresses

On both routers, for FastEthernet 0/0, set the ipv6 address to autoconfigure:

• ipv6 address autoconfig

Make sure interfaces are not shutdown

Use show ipv6 interface brief to make sure they have addresses on the VTEL network

Ping among the router VTEL addresses to ensure connectivity

Step VI: Configure IPv6 RIP so that the Routes are Broadcast

On all 3 routers - and each interface using IPv6 - enable RIP with a process number.

• From interface config mode "ipv6 rip processx enable" in which x can be any number but "1" is common.

Exit config mode: run the show ipv6 route command and you should see all of the networks on each of the routers

You should now be able to ping Champlain Host to Middlebury Host!
