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 out-

put.

-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 proto-

col 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.
