BGP/OSPF/RIP lab with Quagga
This Labs is done with BSDRP under qemu and it explains how to use BSDRP using Quagga.
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 4 routers, here is an example with VirtualBox:
./BSDRP-lab-vbox.sh -i BSDRP_0.32_full_amd64_serial.img -n 4
Routers configuration
Router 1
Interfaces
Enter in Quagga configuration (vtysh):
cli
And configure IP addresse on public interfaces:
router1.bsdrp.net# conf t router1.bsdrp.net(config)# interface em0 router1.bsdrp.net(config-if)# ip address 192.168.12.1/24 router1.bsdrp.net(config-if)# ipv6 address 2001:db8:12::1/64 router1.bsdrp.net(config-if)# interface em1 router1.bsdrp.net(config-if)# ip address 192.168.13.1/24 router1.bsdrp.net(config-if)# ipv6 address 2001:db8:13::1/64 router1.bsdrp.net(config-if)# exit
OSPF
Then configure OSPF:
router1.bsdrp.net(config)# router ospf router1.bsdrp.net(config-router)# router-id 1.1.1.1 router1.bsdrp.net(config-router)# network 192.168.12.0/24 area 0 router1.bsdrp.net(config-router)# exit router1.bsdrp.net(config)# router ospf6 router1.bsdrp.net(config-ospf6)# router-id 1.1.1.1 router1.bsdrp.net(config-ospf6)# interface em0 area 0.0.0.0
BGP
Then configure BGP:
router1.bsdrp.net(config)# router bgp 12 router1.bsdrp.net(config-router)# bgp router-id 1.1.1.1 router1.bsdrp.net(config-router)# neighbor 192.168.12.2 remote-as 12 router1.bsdrp.net(config-router)# neighbor 192.168.12.2 next-hop-self router1.bsdrp.net(config-router)# neighbor 192.168.13.3 remote-as 34 router1.bsdrp.net(config-router)# neighbor 2001:db8:12::2 remote-as 12 router1.bsdrp.net(config-router)# neighbor 2001:db8:12::2 next-hop-self router1.bsdrp.net(config-router)# neighbor 2001:db8:13::3 remote-as 34 router1.bsdrp.net(config-router)# address-family ipv6 router1.bsdrp.net(config-router-af)# neighbor 2001:db8:12::2 activate router1.bsdrp.net(config-router-af)# neighbor 2001:db8:13::3 activate router1.bsdrp.net(config-router-af)# exit

Final testing
Ping router4 loopback from router2 loopback:
[root@router2]~#ping -c 4 -S 192.168.20.2 192.168.40.4 PING 192.168.40.4 (192.168.40.4) from 192.168.20.2: 56 data bytes 64 bytes from 192.168.40.4: icmp_seq=0 ttl=62 time=3.095 ms 64 bytes from 192.168.40.4: icmp_seq=1 ttl=62 time=2.228 ms 64 bytes from 192.168.40.4: icmp_seq=2 ttl=62 time=2.245 ms 64 bytes from 192.168.40.4: icmp_seq=3 ttl=62 time=2.422 ms --- 192.168.40.4 ping statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 2.228/2.498/3.095/0.353 ms [root@router2]~#ping6 -c 4 -S 2001:db8:20::2 2001:db8:40::4 PING6(56=40+8+8 bytes) 2001:db8:20::2 --> 2001:db8:40::4 16 bytes from 2001:db8:40::4, icmp_seq=0 hlim=62 time=9.295 ms 16 bytes from 2001:db8:40::4, icmp_seq=1 hlim=62 time=4.975 ms 16 bytes from 2001:db8:40::4, icmp_seq=2 hlim=62 time=5.732 ms 16 bytes from 2001:db8:40::4, icmp_seq=3 hlim=62 time=5.409 ms --- fc:40::4 ping6 statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 4.975/6.353/9.295/1.720 ms
You need to “force” the source IP addresse to use the loopback (192.168.20.2), otherwise router2 will use the output NIC IP addresse as source (which is 192.168.12.2). But router 4 don't know the network 192.168.12.0/24, then it can't answer to router2 ping.
