Quagga是一款功能比较强大的开源路由软件，支持rip,ripng,ospfv2,ospfv3，bgp等协议。目前最新版本为Quagga
0.99.17。安装Quagga的目的是使装有linux(我采用的是Ubuntu10.04LTS)系统的电脑变成一台路由器，以便今后的实验。之所以选择Quagga是因为它的操作和Cisco的操作是比较相似的。今天用到的电脑需要多块网卡支持(至少两块)。
安装Quagga
首先下载Quagga
0.99.17到硬盘，然后在终端输入
tar –zxvf quagga-0.99.17.tar.gz
进入目录
#cd quagga-0.99.17
配置
#./configure --enable-vtysh
--enable-user=root
--enable-group=root
--enable-vty-group=root
上述命令为打开vty功能(CLI功能)并给予相应用户权限,另有一些初始化配置见文档中.配置完成后会有一些信息表明quagga安装完成后相关文件所在位置。
此时出现错误：
checking for syslog.h... yes
checking for wchar.h... yes
checking for wctype.h... yes
checking for sys/sysctl.h... yes
checking for sys/sockio.h... no
checking for kvm.h... no

--enable-user=root: command not found

注：
①./configure是用来检测你的安装平台的目标特征的(比如它会检查是否有编辑器、函数库，CC或GCC等等)，并根据配置信息生产相应的makefile，它是个shell脚本。
②./configure –h
输入此命令会一一列出当前配置环境所有配置选项
③此输入选项含义为，
启用相应服务程序，并对不用的服务程序进行关闭，其中--enable- user=root --enable-group=root
是限定quagg软件的使用权限。
④配置时易出现如下错误：
/usr/local/lib/libreadline.so:
undefined reference to `PC'
/usr/local/lib/libreadline.so:
undefined reference to `tgetflag'
/usr/local/lib/libreadline.so:

checking for tputs in -ltermcap... no
checking for tputs in -ltinfo... no
checking for tputs in -lcurses... no
checking for tputs in -lncurses... no
checking for main in -lreadline... no
configure:
error: vtysh needs libreadline but was not found and usable on your
system
解决方法：
1 看readline软件包是否安装
sudo apt-get install
libreadline5-dev
2 是否安装ncurses安装包
sudo apt-get install
libncurses5-dev
3 是否安装libncurses5-dev
或libncursesw5-dev软件包
sudo apt-get install
libncursesw5-dev
安装完成之后再重新用配置命令
#./configure --enable-vtysh
#./configure --enable-user=root
#./configure --enable-group=root
#./configure --enable-vty-group=root
之后编译与安装
#make
#make install
之后出现错误
/usr/bin/install: cannot create regular file`/usr/local/lib/libprotobuf.so.0.0.0':
Permission denied
make[3]: *** [install-libLTLIBRARIES] Error 1
make[3]: Exit from catalogue
`/home/alexe/downloads/proto2/protobuf-2.0.0beta/src'
make[2]: *** [install-am] Error 2
make[2]: Exit from catalogue
`/home/alexe/downloads/proto2/protobuf-2.0.0beta/src'
make[1]: *** [install] Error 2
make[1]: Exit from catalogue
`/home/alexe/downloads/proto2/protobuf-2.0.0beta/src'
make: *** [install-recursive] Error 1
可以采用
＃sudo make
＃sudo make install
3.修改文件/etc/services,添加如下内容(某些版本Ubuntu已有,就不用添加了)
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
isid 2608/tcp # ISISd vty
之后查看/etc/services，这个文件，发现已经里面有上面这段东西了。
quagga文件夹下/zebra有一个zebra.conf.sample文件,需建立一个zebra.conf文件并把zebra.conf.sample内容copy进去.
启动Quagga
在终端输入zebra -d即可启动quagga。有可能出现以下错误：
zebra: error while loading shared libraries:
libzebra.so.0: cannot open shared object file: No such file or
directory
解决方法：
在/usr/local/lib下有
lrwxrwxrwx 1 root root 17 2010-06-21 01:52
libzebra.so -> libzebra.so.0.0.0
lrwxrwxrwx 1 root root 17 2010-06-21 01:52
libzebra.so.0 -> libzebra.so.0.0.0
-rwxr-xr-x 1 root root 778556 2010-06-21 01:52
libzebra.so.0.0.0
这可能是由于/lib库出现问题：则
zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ cd
/usr/local/lib
zinkin@zinkin-desktop:/usr/local/lib$ cp libzebra.* /lib
zinkin@zinkin-desktop:/usr/local/lib$ sudo rm libzebra.*
在终端输入zebra -d即可启动quagga。
zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ zebra -d

由于自己的程序没有在root下，所以有些语句前面得用sudo
zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ sudo zebra -d -u
