NCDA Lab Configuration Part 2: Network Configuration

As I continue on building out the NCDA lab, we need to start with our network configurations.  Following the same design that I originally posted, we’re going to start with building the three networks in VMware Workstation.  When you build a new network in Workstation, it automatically configured the IP addressing.  I went with whatever it came up with and only made a change on the 10.10.10.x network to make it completely disparate from any of the other networks.  I could have done it with another 192.168.x.x network but I wanted it to be visually different.

VMware Networks:
  • 192.168.175.x/24 – Site1
  • 192.168.112.x/24 – WAN
  • 10.10.10.x/24 – Site2
Vyatta Configuration:
The Vyatta configuration is pretty straightforward.  I’m using Vyatta Core 6.2 routers.  The Vyatta download is a live CD.  When you build the VM in which you’ll install the software onto, ensure that you add another NIC to the device.  Put each nice on the appropriate Workstation network that you configured above.  Example for Site1:  nic1 – 192.168.175.x network, nic2 – 1921.68.112.x network.  This will allow you to have connectivity to the WAN and Site1.  To install the image perform the following:
  • Boot the VM with the Vyatta Live CD
  • Press Enter when instructed to Boot
  • Log into the image
    • Username – vyatta
    • Password – vyatta
  • Run the command – install-system
  • Take the defaults
  • Reboot the router when complete (Be sure to disconnect the CDROM from the VM before you reboot or it’ll boot back into the Live CD)
Now that the install is complete we need to configure the IP addresses on the eth interfaces as well as setup RIP.  Vyatta is very similar to a Juniper router if you’ve configured one from a CLI perspective.  We’re going to configure eth0 as the local network, and eth1 as the WAN network.  Once the device boots back up perform the following:

Log into the router

Verify that the interfaces are online

Set the IP address on eth0 and eth1

Configure the RIP protocol and commit the changes to the router

Repeat the previous process on the second router with the IP addressing for Site2:  Eth0 – 10.10.10.x/24 and Eth1 – 192.168.112.x/24

Confirm that RIP is running on each device

Now that we have established the networks in Workstation and built the Layer 3 connectivity, we’re ready to move onto building the VMs for the Lab.
