+@chapter Basic commands
+
+There are five routing daemons in use, and there is one manager daemon.
+These daemons may be located on separate machines from the manager
+daemon.  Each of these daemons will listen on a particular port for
+incoming VTY connections.  The routing daemons are:
+
+@itemize @bullet
+@item @command{ripd}, @command{ripngd}, @command{ospfd}, @command{ospf6d}, @command{bgpd}
+@item @command{zebra}
+@end itemize
+
+The following sections discuss commands common to all the routing
+daemons.
+
+@menu
+* Config Commands::             Commands used in config files
+* Common Invocation Options::   Starting the daemons
+* Virtual Terminal Interfaces::  Interacting with the daemons

+
+@cindex Configuration files for running the software
+@c A -not configuration files for installing the software
+@cindex Files for running configurations
+@cindex Modifying the herd's behavior

+* Basic Config Commands::       Some of the generic config commands
+* Sample Config File::          An example config file
+@end menu
+
+
+In a config file, you can write the debugging options, a vty's password,
+routing daemon configurations, a log file name, and so forth. This
+information forms the initial command set for a routing beast as it is
+starting.
+
+Config files are generally found in:
+
+@itemize @asis
+@item @file{@value{INSTALL_PREFIX_ETC}/*.conf}
+@end itemize
+
+Each of the daemons has its own
+config file.  For example, zebra's default config file name is:
+
+@itemize @asis
+@item @file{@value{INSTALL_PREFIX_ETC}/zebra.conf}
+@end itemize
+
+The daemon name plus @file{.conf} is the default config file name. You
+can specify a config file using the @kbd{-f} or @kbd{--config-file}
+options when starting the daemon.

+@subsection Sample Config File
+
+
+Below is a sample configuration file for the zebra daemon.
+
+@example
+@group
+!
+! Zebra configuration file
+!
+hostname Router
+password zebra
+enable password zebra
+!
+log stdout
+!
+!
+@end group
+@end example
+
+'!' and '#' are comment characters.  If the first character of the word
+is one of the comment characters then from the rest of the line forward
+will be ignored as a comment.
+
+@example
+password zebra!password
+@end example
+
+If a comment character is not the first character of the word, it's a
+normal character. So in the above example '!' will not be regarded as a
+comment and the password is set to 'zebra!password'.

+These options apply to all Zebra daemons.
+
+@table @samp
+
+@item -d
+@itemx --daemon
+Runs in daemon mode.
+
+@item -f @var{file}
+@itemx --config_file=@var{file}
+Set configuration file name.
+
+@item -h
+@itemx --help
+Display this help and exit.
+
+@item -i @var{file}
+@itemx --pid_file=@var{file}
+
+Upon startup the process identifier of the daemon is written to a file,
+typically in @file{/var/run}.  This file can be used by the init system
+to implement commands such as @command{@dots{}/init.d/zebra status},
+@command{@dots{}/init.d/zebra restart} or @command{@dots{}/init.d/zebra
+stop}.
+
+The file name is an run-time option rather than a configure-time option
+so that multiple routing daemons can be run simultaneously.  This is
+useful when using Zebra to implement a routing looking glass.  One
+machine can be used to collect differing routing views from differing
+points in the network.
+
+@item -P @var{port}
+@itemx --vty_port=@var{port}
+Set the VTY port number.
+
+@item -v

+@subsection VTY Overview
+
+
+VTY stands for Virtual TeletYpe interface.  It means you can connect to
+the daemon via the telnet protocol.
+
+To enable a VTY interface, you have to setup a VTY password.  If there
+is no VTY password, one cannot connect to the VTY interface at all.
+
+@example
+@group
+% telnet localhost 2601
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
