                     10: There are three steps for installing the software: configuration,
                     11: compilation, and installation.

                     20: commands:

                     45:  
                     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.
                     50: 
                     51: @table @option
                     52: @item --enable-guile
                     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.
                     56: @item --disable-ipv6
                     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.
                     60: @item --disable-zebra
                     61: Do not build zebra daemon.
                     62: @item --disable-ripd
                     63: Do not build ripd.
                     64: @item --disable-ripngd
                     65: Do not build ripngd.
                     66: @item --disable-ospfd
                     67: Do not build ospfd.
                     68: @item --disable-ospf6d
                     69: Do not build ospf6d.
                     70: @item --disable-bgpd
                     71: Do not build bgpd.
                     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.
                     80: @item --enable-snmp
                     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.
                     95: @item --enable-rtadv
                     96: Enable support IPV6 router advertisement in zebra.

                     98: 
                     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.

                    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.

                    127: 
                    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.
                    132:

                    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
                    145: this group.

                    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).
                    153: 
                    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.

                    169: you use @sc{gnu}/Linux, make sure that the current kernel configuration is
