IPv6 on the Network

In this lab you will first configure IPv6 addresses on all the group router interfaces, add ospfv3 (ipv6 ospf) routing commands to BR and R2/R3 to enable full connectivity. The second part of the lab will be to enable router advertisements to all the access networks.

• First remove your access list blocking access to WS1 on R2/R3. Then, if you have not already, trade your WS1 back with your neighbor group.
• Configure all the routers interfaces with IP v6 addresses. Use this network map to assign the addresses. Be sure to enable IPv6 unicast routing on the cisco routers. X in this case is a hexadecimal number between 1 and e. Group 21 is 1, Group 22 is 2, ... , Group 30 is A, Group 31 is B, ... Group 34 is E. The Z IP v6 address facing the ISP is the group number in decimal form.
• You will need to make sure that you initially DO NOT allow router advertisements from R2 and R3. Use the "ipv6 nd suppress-ra" command on each interface BEFORE you add the IPv6 address.
• You will now modify the configuration on R3 to begin sending router advertisements for Net1, Net2 and Net3 (on interfaces eth1/1.XX1, eth1/1.XX2 and eth1/2 respectively).  You do not want to set up router advertisements on Net0 on R3.

Each end system except WS0 (WS1/WS2/WS3) should then get a Global IPv6 address. Now set up Router Advertisements on BR for net 0. All workstations should then have a global IPv6 address. Each router should be configured to advertise their network prefix once every 30 seconds (ipv6 nd ra-interval 30) and use 120 seconds for valid time, and 60 seconds for preferred. (ipv6 nd prefix {prefix} 120 60)

Do not setup any IPv6 static routes as we will be using OSPFv3 instead. Set up OSPFv3 on BR, R2 and R3 to make all networks reachable. Use 131.94.128.0 as the area. Make R2 interface costs 5100 and BR and R3 interface costs 5000.

Now identify each IPv6 address (via ifconfig or ip -f inet6 addr) on each of ws0 eth0, ws1, ws2 and ws3. Make note of both the global and link local ip addresses. On WS1/WS2/WS3 also make note of the IPv6 default route (via ip -f inet6 route command).  After configuration of the IPv6 addresses on the interfaces, do a ping to each router interface.

Grading:

Configuration of Routers - 26 points

IPv6 global addresses of WS0/WS1/WS2/WS3 - 8 points
IPv6 link local addresses of WS0/WS1/WS2/WS3 - 8 points
IPv6 default route address on WS0/WS1/WS2/WS3 - 8 points
