IPv6 Addressing with OSPFv3 – 2

This lab gives you a small 3-router topology, with a basic IPv6 global unicast address design, and sends you forth to configure the basics: IPv6 addressing, routing, and OSPFv3. It’s a big long for these CLI labs, but not too bad – call it an extra 5 minutes compared to most of these kinds of labs. Check out the details below the fold, and get busy configuring!

 

Requirements

The figure shows three routers with Ethernet interfaces. The figure shows the IPv6 prefixes on each link. Then, beside each router sits the host part of the IPv6 address. For example, R1’s G0/2 IPv6 address combines 3000::/64 with ::1 for an address of 3000::1/64.

Your job in this lab: implement the IPv6 addresses shown in the figure, along with IPv6 routing and OSPFv3. The specific rules for this lab are:

  • Configure the IPv6 addresses needed on all the routers per the figure.
  • Configure Router-ID (RID) using the template x.x.x.x, where x is the router number
  • Use OSPF area 0
  • Use OSPF process-ID 15
  • Do not configure any commands beyond those required per the above list

Initial Configuration

 

Example 1: R1 Config

Example 2: R2 Config

Example 3: R3 Config

 

Answer on Paper, or Maybe Test in Lab

Create your own answer, either by typing it in somewhere, or writing it on paper. Try to avoid using your notes – one of points of these labs is to move you from being able to read someone else’s config to being able to create your own from scratch.

You can easily test this lab with a few show commands. First, R1 and R3 should list one OSPFv3 neighbor, and R2 should list two neighbors (show ipv6 ospf neighbor). Each router should list two OSPF routes (show ipv6 route), although the OSPF-learned routes will be different on each router. You can check the interface IPv6 addresses with show ipv6 interface, and the OSPF router ID with show ipv6 ospf database.

 

Do this Lab with Cisco’s VIRL

You can do these labs on paper and still get a lot out of the lab. As an extra help, we have added files for the Virtual Internet Routing Lab (VIRL) software as well. The .VIRL file found here is a file that when used with VIRL will load a lab topology similar to this lab’s topology, with the initial configuration shown in the lab as well. This section lists any differences between the lab exercise and the .VIRL file’s topology and configuration.

Network Device Info

The .VIRL topology matches this lab topology exactly. The host info does as well.

 

Host Device Info

This lab does not have any specific Host device information.

 

Handy Host Commands:

To see PC IP address: ifconfig eth1

Ping example: ping6 -c 4 2001:DB8:1:1::100

Trace example: tracepath6 2001:DB8:1:1::100
