Lab Objective:
The focus of this lab is to understand OSPFv3 implementation and configuration in Cisco IOS routers. Additional technologies include Frame Relay, summarization and path control.
Lab Topology:
The lab network topology is illustrated below:
|
IMPORTANT NOTE If you are using the www.howtonetwork.net racks, please bring up the LAN interfaces connected to the routers by issuing the no shutdown command on the connected switches. If you are using a home lab with no interface fastethernet 0/0 Alternately, you can simply connect the interfaces to a hub or switch if you have one available in your own lab. Also, if you are using the www.howtonetwork.net racks, configure R3 as the Frame Relay switch using the following configuration commands: hostname R3-Frame-Relay-Switch |
Task 1
Configure hostnames and IP addressing on all routers as illustrated in the network topology.
Task 2
Configure the Frame Relay network so that all routers can ping each others’ WAN interfaces. This connectivity should be for Link Local addresses only. Verify the configuration.
Task 3
Configure OSPF over the Frame Relay WAN connectivity R1, R2, and R4. Ensure that there is no DR/BDR election held on the WAN segment. Additionally, OSPFv3 should use Unicast packets to send protocol messages. Verify your configuration using the appropriate commands.
Task 4
Redistribute the LAN subnets connected to R1 into OSPF. Configure R1 so that only a single route is advertised to R2 and R4. Verify that these routers can ping the three LAN subnets connected to R1 although they have only a single route for the subnets in their routing tables.
Task 5
Advertise the subnet connected to R2 and R4s LAN interfaces via OSPF. Do NOT redistribute this subnet into OSPF. These routes should be received as inter-area routes on R1. Ensure that no OSPFv3 messages are sent out these interfaces. Verify your configuration.
Task 6
Configure OSPF so that R1 prefers the path via R2 to reach the 3ffe:abcd:1111:5/64 IPv6 subnet connected to R2 and R4. You are NOT allowed to implement any configurations on R1 to complete this task. Additionally, you are NOT allowed to modify interface bandwidth or cost values, or default administrative distance values. Finally, you can NOT use any static routes or redistribution to complete this task. Verify your configuration using the appropriate commands.
