1. Quagga Install And Configuration

Quagga Install Guide:

http://blog.chinaunix.net/uid-25513153-id-212328.html

Download Quagga:

http://download.savannah.gnu.org/releases/quagga/quagga-1.2.1.tar.gz

Unzip and Configure:

$ ./configure --enable-vtysh --enable-user=root --enable-group=root --enable-vty-group=root

If GNU awk is required:

$ sudo apt-get install gawk

If libreadline is required:

$ sudo apt-get install libreadline6 libreadline6-dev

If libcares is required:

$ sudo apt-get install libc-ares-dev

Make:

$ make

If aclocal-1.15 is missing:

$ sudo apt-get install automake

If makeinfo is missing:

$ sudo apt-get install texinfo

Make install:

$ sudo make install

Make new file, copy zebra.conf.sample to zebra.conf:

$ cd /usr/local/etc

$ sudo cp zebra.conf.sample zebra.conf

Quagga(Zebra) Service Start:

$ sudo zebra -d

If zebra: error while loading shared libraries: libzebra.so.1: cannot open shared object file: No such file or directory

$ cd /usr/local/lib

$ sudo cp libzebra.* /lib

$ sudo rm libzebra.*

Connect to zebra using telnet(password zebra):

$ telnet localhost 2601

2. Run OSPF Experiment (One Mininet)

Experiment Topo:

Create Zebra Configuration File for router r1 and r2:

$ cd /usr/local/etc

$ cp zebra.conf.sample r1zebra.conf

$ cp zebra.conf.sample r2zebra.conf

Create OSPF Configuration File for router r1 and r2:

$ cd /usr/local/etc

$ cp ospfd.conf r1ospfd.conf

$ cp ospfd.conf r2ospfd.conf

Edit OSPF configuration File:

Edit r1ospfd.conf

hostname r1_ospfd
password 123
enable password 123

router ospf
  ospf router-id 10.0.3.10
  network 10.0.3.0/24 area 0
  network 10.0.1.0/24 area 0
debug ospf event
log file /usr/local/etc/r1ospfd.log

Edit r2ospfd.conf

hostname r2_ospfd
password 123
enable password 123

router ospf
  ospf router-id 10.0.3.20
  network 10.0.3.0/24 area 0
  network 10.0.2.0/24 area 0
debug ospf event
log file /usr/local/etc/r2ospfd.log

Start Mininet Script:

$ sudo python QuaggaOSPF.py

Ping test:

mininet> pingall

It may take a while(40s) to add route.

3. Run OSPF Experiment (Hybrid)

Experiment Topo:

Run Mininet Script on PC1:

$ sudo python QuaggaOSPF (hybrid).py

Copy Zebra Configuration File on PC2:

$ cp zebra.conf.sample zebra.conf

Copy and Edit OSPF Configuration File on PC2:

$ cd /usr/local/etc

$ cp ospfd.conf.sample ospfd.conf

$ nano ospfd.conf

hostname hp2_ospfd
password 123
enable password 123

router ospf
 ospf router-id 10.0.3.20
 network 10.0.3.0/24 area 0
 network 10.0.2.0/24 area 0

Run Zebra and OSPF on PC2:

$ sudo zebra -d

$ sudo ospfd -d

Configure IP address and gateway on Pi:

$ sudo ifconfig eth0 10.0.2.100/24

$ sudo route add default gw 10.0.2.20

Ping Test:

mininet> h1 ping 10.0.2.100

It may take a while(40s) to add route.

4. Run SDN and Non-SDN Combination Experiment

Experiment Topo:

Edit OSPF Configuration Files:

$ cd /usr/local/etc

$ sudo nano r1ospfd.conf

hostname r1_ospfd
password 123
enable password 123

router ospf
  ospf router-id 10.0.3.10
  network 10.0.3.0/24 area 0
  network 10.0.1.0/24 area 0
  network 10.0.4.0/24 area 0
debug ospf event
log file /usr/local/etc/r1ospfd.log

$ sudo nano r2ospfd.conf

hostname r2_ospfd
password 123
enable password 123

router ospf
  ospf router-id 10.0.3.20
  network 10.0.3.0/24 area 0
  network 10.0.2.0/24 area 0
  network 10.0.5.0/24 area 0
debug ospf event
log file /usr/local/etc/r2ospfd.log

Run Mininet Script:

$ sudo python QuaggaOSPF (SDN+NONSDN).py

Ping Test:

mininet> pingall

It may take a while(40s) to add route.

Trouble Shooting

1.OSPF service wait a long time before adding route.
