BGP/OSPF/RIP/ISIS/BABEL lab with FRRouting

This Labs is done with BSDRP under qemu and it explains how to use BSDRP using FRRouting (Quagga fork).

Presentation

Network diagram

Here is the logical and physical view:

Setting-up the lab

Downloading BSD Router Project images

Download BSDRP serial image (prevent to have to use an X display) on Sourceforge.

Download Lab scripts

More information on these BSDRP lab scripts available on How to build a BSDRP router lab.

Start the lab with 5 routers, here is an example with VirtualBox:

./BSDRP-lab-vbox.sh -i BSDRP-1.91-full-amd64-serial.img.xz -n 7

Routers configuration

All these routers can be configured with labconfig tool (use it only on a lab, because it will replace your current running configuration):

labconfig frr_vm[VM-NUMBER]

Final testing

Ping router7 loopback from router1 loopback:

[root@router1]~# ping -c 4 -S 192.168.10.1 192.168.70.7

Don't forget to “force” the source IP address to use the loopback, otherwise router1 will use the output NIC IP address as source.
