10 There are three steps for installing the software: configuration,
11 compilation, and installation.
14 * Configure the Software::
15 * Build the Software::
16 * Install the Software::
19 The easiest way to get Quagga running is to issue the following

38 @subsection The Configure script and its options
40 @cindex Configuration options
41 @cindex Options for configuring
43 @cindex Distribution configuration
44 @cindex Options to @code{./configure}
46 Quagga has an excellent configure script which automatically detects most
47 host configurations. There are several additional configure options you can
48 use to turn off IPv6 support, to disable the compilation of specific
49 daemons, and to enable SNMP support.
53 Turn on compilation of the zebra-guile interpreter. You will need the
54 guile library to make this. zebra-guile implementation is not yet
55 finished. So this option is only useful for zebra-guile developers.
57 Turn off IPv6 related features and daemons. Quagga configure script
58 automatically detects IPv6 stack. But sometimes you might want to
59 disable IPv6 support of Quagga.
61 Do not build zebra daemon.
64 @item --disable-ripngd
68 @item --disable-ospf6d
72 @item --disable-bgp-announce
73 Make @command{bgpd} which does not make bgp announcements at all. This
74 feature is good for using @command{bgpd} as a BGP announcement listener.
75 @item --enable-netlink
76 Force to enable @sc{gnu}/Linux netlink interface. Quagga configure
77 script detects netlink interface by checking a header file. When the header
78 file does not match to the current running kernel, configure script will
79 not turn on netlink support.
81 Enable SNMP support. By default, SNMP support is disabled.
82 @item --enable-opaque-lsa
83 Enable support for Opaque LSAs (RFC2370) in ospfd.
84 @item --disable-ospfapi
85 Disable support for OSPF-API, an API to interface directly with ospfd.
86 OSPF-API is enabled if --enable-opaque-lsa is set.
87 @item --disable-ospfclient
88 Disable building of the example OSPF-API client.
89 @item --enable-ospf-te
90 Enable support for OSPF Traffic Engineering Extension (internet-draft) this
91 requires support for Opaque LSAs.
92 @item --enable-multipath=@var{ARG}
93 Enable support for Equal Cost Multipath. @var{ARG} is the maximum number
94 of ECMP paths to allow, set to 0 to allow unlimited number of paths.
96 Enable support IPV6 router advertisement in zebra.
99 You may specify any combination of the above options to the configure
100 script. By default, the executables are placed in @file{/usr/local/sbin}
101 and the configuration files in @file{/usr/local/etc}. The @file{/usr/local/}
102 installation prefix and other directories may be changed using the following
103 options to the configuration script.
106 @item --prefix=@var{prefix}
107 Install architecture-independent files in @var{prefix} [/usr/local].
108 @item --sysconfdir=@var{dir}
109 Look for configuration files in @var{dir} [@var{prefix}/etc]. Note
110 that sample configuration files will be installed here.
111 @item --localstatedir=@var{dir}
112 Configure zebra to use @var{dir} for local state files, such
113 as pid files and unix sockets.
117 % ./configure --disable-ipv6
120 This command will configure zebra and the routing daemons.
122 @node Least-Privilege support
123 @subsection Least-Privilege support
125 @cindex Quagga Least-Privileges
126 @cindex Quagga Privileges
128 Additionally, you may configure zebra to drop its elevated privileges
129 shortly after startup and switch to another user. The configure script will
130 automatically try to configure this support. There are three configure
131 options to control the behaviour of Quagga daemons.
134 @item --enable-user=@var{user}
135 Switch to user @var{ARG} shortly after startup, and run as user @var{ARG}
137 @item --enable-group=@var{group}
138 Switch real and effective group to @var{group} shortly after
140 @item --enable-vty-group=@var{group}
141 Create Unix Vty sockets (for use with vtysh) with group owndership set to
142 @var{group}. This allows one to create a seperate group which is
143 restricted to accessing only the Vty sockets, hence allowing one to
144 delegate this group to individual users, or to run vtysh setgid to
148 The default user and group which will be configured is 'quagga' if no user
149 or group is specified. Note that this user or group requires write access to
150 the local state directory (see --localstatedir) and requires at least read
151 access, and write access if you wish to allow daemons to write out their
152 configuration, to the configuration directory (see --sysconfdir).
154 On systems which have the 'libcap' capabilities manipulation library
155 (currently only linux), the quagga system will retain only minimal
156 capabilities required, further it will only raise these capabilities for
157 brief periods. On systems without libcap, quagga will run as the user
158 specified and only raise its uid back to uid 0 for brief periods.

165 @cindex Linux configurations
167 There are several options available only to @sc{gnu}/Linux systems:
168 @footnote{@sc{gnu}/Linux has very flexible kernel configuration features}. If
169 you use @sc{gnu}/Linux, make sure that the current kernel configuration is
170 what you want. Quagga will run with any kernel configuration but some
171 recommendations do exist.
176 Kernel/User netlink socket. This is a brand new feature which enables an
177 advanced interface between the Linux kernel and zebra (@pxref{Kernel Interface}).
179 @item CONFIG_RTNETLINK
181 This makes it possible to receive netlink routing messages. If you
182 specify this option, @command{zebra} can detect routing information
183 updates directly from the kernel (@pxref{Kernel Interface}).
185 @item CONFIG_IP_MULTICAST
187 This option should be specified when you use @command{ripd} (@pxref{RIP}) or
188 @command{ospfd} (@pxref{OSPFv2}) because these protocols use multicast.
192 IPv6 support has been added in @sc{gnu}/Linux kernel version 2.2. If you
193 try to use the Quagga IPv6 feature on a @sc{gnu}/Linux kernel, please
194 make sure the following libraries have been installed. Please note that
195 these libraries will not be needed when you uses @sc{gnu} C library 2.1
201 The @code{inet6-apps} package includes basic IPv6 related libraries such
202 as @code{inet_ntop} and @code{inet_pton}. Some basic IPv6 programs such
203 as @command{ping}, @command{ftp}, and @command{inetd} are also
204 included. The @code{inet-apps} can be found at
205 @uref{ftp://ftp.inner.net/pub/ipv6/}.
208 The @code{net-tools} package provides an IPv6 enabled interface and
209 routing utility. It contains @command{ifconfig}, @command{route},
210 @command{netstat}, and other tools. @code{net-tools} may be found at
211 @uref{http://www.tazenda.demon.co.uk/phil/net-tools/}.

219 After configuring the software, you will need to compile it for your
220 system. Simply issue the command @command{make} in the root of the source
221 directory and the software will be compiled. If you have *any* problems
222 at this stage, be certain to send a bug report @xref{Bug Reports}.

242 Installing the software to your system consists of copying the compiled
243 programs and supporting files to a standard location. After the
244 installation process has completed, these files have been copied
245 from your work directory to @file{/usr/local/bin}, and @file{/usr/local/etc}.
247 To install the Quagga suite, issue the following command at your shell
248 prompt: @command{make install}.
256 Quagga daemons have their own terminal interface or VTY. After
257 installation, you have to setup each beast's port number to connect to
258 them. Please add the following entries to @file{/etc/services}.
261 zebrasrv 2600/tcp # zebra service
262 zebra 2601/tcp # zebra vty
263 ripd 2602/tcp # RIPd vty
264 ripngd 2603/tcp # RIPngd vty
265 ospfd 2604/tcp # OSPFd vty
266 bgpd 2605/tcp # BGPd vty
267 ospf6d 2606/tcp # OSPF6d vty
268 ospfapi 2607/tcp # ospfapi
269 isisd 2608/tcp # ISISd vty
272 If you use a FreeBSD newer than 2.2.8, the above entries are already
273 added to @file{/etc/services} so there is no need to add it. If you
274 specify a port number when starting the daemon, these entries may not be
277 You may need to make changes to the config files in
278 @file{@value{INSTALL_PREFIX_ETC}/*.conf}. @xref{Config Commands}.
