How to use quagga on CentOS6 part1 : installation , initial setup

I’m newbie to quagga.
Here’s installation logs including trial and error.

VLAN1 :192.168.1.0/24
VLAN2 : 192.168.0.0/24
VLAN3 : 192.168.2.0/24

client1 -- SW – quagga1 – SW – quagga2 – SW – client2

- Client1 ( VLAN1 )
192.168.01.10

- quagga1
eth0 : 192.168.0.254 ( VLAN2 )
eth1 : 192.168.1.254 ( VLAN1 )

- quagga2
eth0 : 192.168.0.253 ( VLAN1)
eth1 : 192.168.2.254 (VLAN3)

- Client2

install quagga via yum

# cat /etc/centos-release CentOS release 6.3 (Final) # uname -ri 2.6.32-279.14.1.el6.x86_64 x86_64 # yum install -y quagga

You may want to install telnet client to connect to quagga if you have not installed it.

# yum install -y telnet

# rpm -ql `rpm -qa | grep quagga` /etc/logrotate.d/quagga /etc/quagga /etc/quagga/bgpd.conf.sample /etc/quagga/bgpd.conf.sample2 /etc/quagga/ospf6d.conf.sample /etc/quagga/ospfd.conf.sample /etc/quagga/ripd.conf.sample /etc/quagga/ripngd.conf.sample /etc/quagga/vtysh.conf.sample /etc/quagga/zebra.conf.sample /etc/rc.d/init.d/bgpd /etc/rc.d/init.d/ospf6d /etc/rc.d/init.d/ospfd /etc/rc.d/init.d/ripd /etc/rc.d/init.d/ripngd /etc/rc.d/init.d/zebra /etc/sysconfig/quagga <snip>

# egrep -v ^# /etc/sysconfig/quagga QCONFDIR="/etc/quagga" BGPD_OPTS="-A 127.0.0.1 -f ${QCONFDIR}/bgpd.conf" OSPF6D_OPTS="-A ::1 -f ${QCONFDIR}/ospf6d.conf" OSPFD_OPTS="-A 127.0.0.1 -f ${QCONFDIR}/ospfd.conf" RIPD_OPTS="-A 127.0.0.1 -f ${QCONFDIR}/ripd.conf" RIPNGD_OPTS="-A ::1 -f ${QCONFDIR}/ripngd.conf" ZEBRA_OPTS="-A 127.0.0.1 -f ${QCONFDIR}/zebra.conf" ISISD_OPTS="-A ::1 -f ${QCONFDIR}/isisd.conf" WATCH_OPTS="" WATCH_DAEMONS="zebra bgpd ospfd ospf6d ripd ripngd"

startup script is /etc/init.d/zebra ?
this script “/etc/init.d/zebra” seems to read /etc/sysconfig/quagga file.

# egrep -i ^conf /etc/init.d/zebra CONF_FILE=/etc/quagga/zebra.conf

start zebra

# /etc/init.d/zebra start Starting zebra: [  OK  ]

nnn , no log files

# ls /var/log/quagga/

# /etc/init.d/zebra status zebra (pid 1261) is running......

# lsof -ni:2601 COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME zebra   1261 quagga    9u  IPv4   8433      0t0  TCP 127.0.0.1:discp-client (LISTEN)

it seems that only zebra process is running.

# cat /proc/1261/cmdline zebra-d-A127.0.0.1-f/etc/quagga/zebra.conf # cat /proc/1261/environ HOSTNAME=centos6-64-vm1.localdomainTERM=vt100-navSHELL=/bin/bashHISTSIZE=1000USER=rootLS_COLORS=MAIL=/var/spool/mail/rootPATH=/sbin:/usr/sbin:/bin:/usr/binPWD=/rootLANG=CHISTCONTROL=ignoredupsSHLVL=3HOME=/rootLOGNAME=rootLESSOPEN=|/usr/bin/lesspipe.sh %sG_BROKEN_FILENAMES=1_=/usr/sbin/zebra

config files are stored under /etc/quagga/*.conf

# ls /etc/quagga/*.conf /etc/quagga/vtysh.conf  /etc/quagga/zebra.conf

needs to configure *.conf before starting zebra ?

# cat /etc/quagga/zebra.conf hostname centos6-64-vm1.localdomain # cat /etc/quagga/vtysh.conf #

stop zebra

# /etc/init.d/zebra stop Shutting down zebra: [  OK  ]

sample configuration files are under /usr/quagga directory.

# ls /etc/quagga/*.sample /etc/quagga/bgpd.conf.sample    /etc/quagga/ripngd.conf.sample /etc/quagga/ospf6d.conf.sample  /etc/quagga/vtysh.conf.sample /etc/quagga/ospfd.conf.sample   /etc/quagga/zebra.conf.sample /etc/quagga/ripd.conf.sample

about listening port

zebrasrv      2600/tcp  # zebra service zebra         2601/tcp  # zebra vty ripd          2602/tcp  # RIPd vty ripngd        2603/tcp  # RIPngd vty ospfd         2604/tcp  # OSPFd vty bgpd          2605/tcp  # BGPd vty ospf6d        2606/tcp  # OSPF6d vty ospfapi       2607/tcp  # ospfapi isisd         2608/tcp  # ISISd vty

[ configure zebra.conf ]

# cat zebra.conf hostname quagga1 password zebra enable password zebra

okay , can logon to the quagga.

# /etc/init.d/zebra start Starting zebra: [  OK  ]
