This chapter will describe how to start the lab.
Setting-up the lab
See instruction on How to build a BSDRP router lab.
Starting the lab
If you would to use Virtualbox, start this lab withStart the Virtualbox based lab with this command:
virtualbox.sh -i BSDRP_0.35_full_amd64_vga.img -n 7 -l 1 -c
The output should be like that:
BSD Router Project: VirtualBox lab script
Creating lab with 7 router(s):
- 1 LAN between all routers
- Full mesh ethernet point-to-point link between each routers
- One NIC connected to the shared LAN with the host
Router1 have the following NIC:
em0 connected to Router2.
em1 connected to Router3.
em2 connected to Router4.
em3 connected to Router5.
em4 connected to Router6.
em5 connected to Router7.
em6 connected to LAN number 1.
em7 connected to shared-with-host LAN.
Router2 have the following NIC:
em0 connected to Router1.
em1 connected to Router3.
em2 connected to Router4.
em3 connected to Router5.

Connect to the router 1 by vnc client on port 5901
Connect to the router 2 by vnc client on port 5902
Connect to the router 3 by vnc client on port 5903
Connect to the router 4 by vnc client on port 5904
Connect to the router 5 by vnc client on port 5905
Connect to the router 6 by vnc client on port 5906
Connect to the router 7 by vnc client on port 5907
You need to configure an IP address in these range for communicating with the host:
inet 192.168.56.1 netmask 0xffffff00 broadcast 192.168.56.255
inet6 fe80::800:27ff:fe00:0%vboxnet0 prefixlen 64 scopeid 0x5
Routers configuration
Router 1
Configure hostname, disable Quagga and Enable Bird, edit /etc/rc.conf
hostname="R1.bsdrp.net" ifconfig_em6="10.0.6.1/24" ipv6_ifconfig_em6="2001:db8:6::1 prefixlen 64" ifconfig_em0="10.0.1.1/24" ipv6_ifconfig_em0="2001:db8:1::1 prefixlen 64" quagga_enable="NO" bird_enable="YES" bird6_enable="YES"
Then apply changes:
hostname R1.bsdrp.net /usr/local/etc/rc.d/quagga stop /etc/rc.d/netif restart /etc/rc.d/network_ipv6 restart
Edit /usr/local/etc/bird.conf and put theses lines in:
# Configure logging
log syslog all;
log "/var/log/bird.log" all;
log stderr all;
# Override router ID
router id 0.0.0.101;
# Sync bird routing table with kernel
protocol kernel {
import all;
export all;
}
# Include device route (warning, a device route is a /32)
protocol device {
scan time 10;
}
# Include directly connected network
# with the exepction of em7
protocol direct {
interface "-em7","*";
}
# Set-up a filter called "bgp_out" that will restrict
# route 10.0.1.0/24 to be advertissed
# without, all /32 device route will be advertissed too
filter bgp_out {
if (net = 10.0.1.0/24 ) &&
(source = RTS_DEVICE) then accept;
else reject;
}
protocol bgp R2 {
local as 100;
neighbor 10.0.6.2 as 100;
import all;
export filter bgp_out;
}
Now start bird process :
[root@R1]~#/usr/local/etc/rc.d/bird start Starting bird.
Now, IPv6 bird process,
edit /usr/local/etc/bird6.conf and put theses lines in:
# Configure logging
log syslog all;
log "/var/log/bird6.log" all;
log stderr all;
# Override router ID

}
protocol bgp R2 {
local as 100;
neighbor 2001:db8:6::2 as 100;
import all;
export all;
}
Now start bird IPv6 process:
[root@R1]~#/usr/local/etc/rc.d/bird6 start Starting bird.
Save configuration:

Then apply changes:
hostname R2.bsdrp.net /usr/local/etc/rc.d/quagga stop /etc/rc.d/netif restart /etc/rc.d/network_ipv6 restart
Edit /usr/local/etc/bird.conf and put theses lines in:

rr client;
}
protocol bgp R3 {
local as 100;
neighbor 10.0.6.3 as 100;

Then configure BGP:

Check that BGP IPv4 and IPV6 peers are UP between R6 and R5:

And check that R6 learn the IPv4/IPv6 routes advertised by R5:
