Quagga is a software suite that implement multiprotocol routing support (OSPFv2, OSPFv3, RIPv1, RIPv2, RIPng and BGP-4). The zebra daemon is the core of quagga that manage the interaction of kernel routing table and the daemons for individual routing protocols. Each daemon has its own config file in /etc/quagga directory.

I’ll configure two Routers with FreeBSD 9.0 running RIPv2 with key authentication, sharing the routing tables of local networks between the two routers. This is my network:

Image
1.- Install quagga:

# cd /usr/ports/net/quagga && make install clean

2.- Edit /etc/rc.conf :

quagga_enable="YES"
quagga_daemons="zebra ripd"
gateway_enable="YES"

3.- Setting up package forwarding:

# sysctl -w net.inet.ip.forwarding=1

4.- Copy config example files:

# cp /usr/local/share/examples/quagga/zebra.conf.sample /usr/local/etc/quagga/zebra.conf
# cp /usr/local/share/examples/quagga/ripd.conf.sample /usr/local/etc/quagga/ripd.conf

5.- Starting quagga:

# /usr/local/etc/rc.d/quagga start

– Check the port number 2601 (zebra) and 2602 (ripd) are listening by the server:

6.- Login to the zebra vty to setting up the interfaces:

  • Router 1:
# telnet localhost 2601
User Access Verification
Password:
Router> enable
Password:
Router# config term
Router(config)# interface em0
Router(config-if)# ip address 192.168.0.20/24
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# interface em1
Router(config-if)# ip address 172.16.1.1/24
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# hostname quagga01
quagga01(config)# write
Configuration saved to /usr/local/etc/quagga/zebra.conf
  • Router 2:
# telnet localhost 2601
User Access Verification
Password:
Router> enable
Password:
Router# config term
Router(config)# interface em0
Router(config-if)# ip address 192.168.0.21/24

Router(config-if)# exit
Router(config)# interface em1
Router(config-if)# ip address 172.16.2.1/24
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# hostname quagga02
quagga02(config)# write
Configuration saved to /usr/local/etc/quagga/zebra.conf

7.- Login to the ripd vty to setting up the RIP routing protocol:

  • Router 1:
# telnet localhost 2602
User Access Verification
Password:
ripd> enable
ripd# config term
ripd(config)# router rip
ripd(config-router)# version 2
ripd(config-router)# network 192.168.0.0/24
ripd(config-router)# network 172.16.1.0/24
ripd(config-router)# passive-interface em1
ripd(config-router)# exit
ripd(config)# key chain mykey1
ripd(config-keychain)# key 1
ripd(config-keychain-key)# key-string quagga
ripd(config-keychain-key)# exit
ripd(config-keychain)# exit
ripd(config)# interface em0
ripd(config-if)# ip rip authentication key-chain mykey1
ripd(config-if)# ip rip authentication mode md5
ripd(config-if)# exit
ripd(config)# write
Configuration saved to /usr/local/etc/quagga/ripd.conf
  • Router 2:
# telnet localhost 2602
User Access Verification
Password:
ripd> enable
ripd# config term
ripd(config)# router rip
ripd(config-router)# version 2
ripd(config-router)# network 192.168.0.0/24
ripd(config-router)# network 172.16.2.0/24
ripd(config-router)# passive-interface em1
ripd(config-router)# exit
ripd(config)# key chain mykey1
ripd(config-keychain)# key 1
ripd(config-keychain-key)# key-string quagga
ripd(config-keychain-key)# exit
ripd(config-keychain)# exit
ripd(config)# interface em0
ripd(config-if)# ip rip authentication key-chain mykey1
ripd(config-if)# ip rip authentication mode md5
ripd(config-if)# exit
ripd(config)# write
Configuration saved to /usr/local/etc/quagga/ripd.conf
