NAME

bgpd — BGP routing daemon for IPv6

SYNOPSIS

/usr/sbin/bgpd [-C | -c] [-f config_file] [-N] [-n] [-q] [-t trace_options] [trace_file]

DESCRIPTION

bgpd is a routing daemon that works with Route Administration Manager (RAMD) for IPv6. This routing daemon is an implementation of Border Gateway Protocol (BGP) for IPv6. bgpd is invoked automatically if it is enabled in the /etc/ramd.conf configuration file.

BGP exchanges information across the Autonomous System (AS) and uses the path-vector algorithm to select the best path. It conforms to IETF RFC 1771, RFC 2545 RFC 2858, and RFC 3392.

This release supports only IPv6 route exchange.

Options

bgpd supports the following command-line options:

-C | -c

Parses the configuration file for syntax errors and terminates bgpd. bgpd exits with status 0 if the configuration file contains no error. In case of any error, bgpd exits with a non-zero value. bgpd prints the configuration file errors, if any, to the standard output.

-C and -c perform the same function.

-f config_file

Specifies an alternate configuration file to be used by bgpd. By default, bgpd uses the /etc/ramd.conf configuration file.

-N

Specifies that bgpd runs as a normal process and not as a daemon.

-n

Specifies that bgpd does not modify the kernel forwarding table. That is, bgpd must not send route updates to ramd.

-q

Suppresses stderr messages of bgpd. Using this option, informational messages that are printed to the standard output can be suppressed and error messages can be logged using syslogd(1M). By default, bgpd logs the syslog errors to /var/adm/syslog/syslog.log.

-t trace_options

Specifies a comma-separated list of trace options that must be enabled during startup of bgpd. No space is allowed between this option and its arguments. See ramd.conf(4) for information on valid trace options and tracing.

trace_file

Name of the file used by bgpd to log tracing information. If trace options are specified without specifying a trace file, bgpd uses the default trace file /var/tmp/bgpd/bgpd.log.

Signal Processing

The following signals can be used to control bgpd:

SIGHUP

Specifies bgpd to reread the configuration file. bgpd reads the configuration file and reconfigures its policies.

SIGINT

Specifies that the current state of bgpd is written to /var/tmp/bgpd/bgpd.dump.

SIGTERM

Graceful shutdown. On receipt of SIGTERM, bgpd attempts a graceful shutdown. All protocol routes are removed from the kernel's routing table on receipt of SIGTERM.

SIGUSR1

Toggle tracing. If the tracing is currently enabled, this signal suspends tracing and closes trace file. If tracing is currently disabled, the trace file will be reopened and tracing initiated. This is used to move trace files.

It is not possible to use SIGUSR1 if tracing is not enabled in the configuration file.
