Intro to IPv6

Purpose:

• In this lab, we learn how to configure IPv6 within a small enterprise network environment such that several company networks are able to ping each other using their assigned IPv6 addresses.

Materials:

• Cisco Packet Tracer
• Packet Tracer Starter File

Objective:

• The completed lab should look similar to below:

• Additionally, the following network table was used to help configure this environment:

Router	Interface	IPv6 Network Prefix
VTEL ISP	Fa0/0	1800:2200:185::/64
Champlain College	Fa0/1 (to internal)	2620:E4:C000::/64
Middlebury College	Fa0/1 (to internal)	2001:1890:139D::/64

Working Notes/Documentation:

Configuring IPv6 Networking for Champlain/Middlebury Routers

• Repeat the following commands for each Router:

# Configuring IPv6 Network Prefix for the Router's Internal Networks
ena
conf t
ipv6 general-prefix <prefix-name (ex. "champ-pre")> <prefix-ID (ex. "x:x:x:x::/64")>

# Enable IPv6 Local Routing
ena
conf t
ipv6 unicast-routing

# Configure Interface w/ new IPv6 Network Prefix
int fa0/1
ipv6 address <x:x:x:x::1/64>
ipv6 rip process1 enable # --> Enables IPv6 RIP Routing
no shut

# Configure Outbound Interface (to VTEL ISP)
int fa0/0
ipv6 address autoconfig
ipv6 rip process1 enable # --> Enables IPv6 RIP Routing
no shut

# Verify Correct IPv6 Address for VTEL ISP
ena
conf t
show ipv6 interface brief # --> This should be a VTEL ISP IPv6 Address

VTEL Router Config

# Enables IPv6 Local Unicast Routing
ena
conf t
ipv6 unicast-routing

# Configure interface w/ EUI-64 Address
int fa0/0
ipv6 address <x.x.x.x::64> eui-64
ipv6 rip process1 enable
no shut

# Useful Command to View what IPv6 Address is Assigned
ena
show ipv6 interface brief # --> Verify that the address is assigned correctly for this network

Configuring IPv6 Network Host/PC using SLAAC

• On each Workstation, enable Automatic IPv6 Configuration
  • This will allow the system to obtain the necessary IPv6 Network Prefix from the Default Gateway as well as assign its own IPv6 address via SLAAC
• Following this, you should now be able to ping between your host system and the local router

Useful Troubleshooting Commands

# Checking IPv6 Address on a Cisco Router
ena
show ipv6 interface brief

# Show Available IPv6 Routes on a Cisco Router
ena
show ipv6 route

Deliverables:

Deliverable 1:

^^ Screenshots of the "show ipv6 route" command being run on all 3 lab Routers (Champlain, Middlebury, and VTEL Routers) to show that the IPv6 RIP routes were properly configured.

Deliverable 2:

^^ Screenshot of a successful ipv6 ping between the Champlain (2620:e4:c000:0:200:cff:fe92:1dcd) and Middlebury Hosts (2001:1890:139d:0:202:17ff:fed9:e22b)
