SBGP(8)

NAME

sbgp - a simple BGP4 speaker and listener

DESCRIPTION

Usage: sbgp [-01av] [-i binary_data_in_file] [-o binary_data_out_file]

[-l log_file] [-f config_file] [-c port] [-d port] [-s

src_addr]

[-E seconds_idle_after_in_file_EOF]
[ASmy_as] [peer_ip ASpeer_as]...

SBGP is a simple BGP4 speaker and listener. SBGP does not apply policy to routes, nor does it maintain a routing information base (RIB) of routes it has previously learned. Rather, SBGP provides a mechanism for monitoring routing information sent from a peer, and for injecting routing information into a peering session.

Synopsis

sbgp [-av] [-i binary_data_in_file] [-o binary_data_out_file] [-l log_file] [-f config_file] [-c port] [-d port] [my AS] [peer_IP peer_AS]...

Options

-a

Accept peering BGP connection from all peers.

-v

Turn on verbose logging to standard output.

-i binary_data_in_file

Inject routes from this file into every peering session. Use the

file

name 'stdin' to read input from standard in.

-o binary_data_out_file

Save route updates from all peering sessions into this file. Use the

file name 'stdout' to write output to standard out.

-l log_file
Write logging information to this file. By default, SBGP logs to

/tmp/bgp.log.pid, where pid is the process ID number of the SBGP process.

-f config_file
Not supported yet

-p
Not supported yet

-c port
Connect to this port on all BGP peers.

-d port
Listen on this port for BGP peering connections.

[my AS] [peer_IP peer_AS]...
Use my AS for my Autonymous System number and open peering sessions

with each peer_IP address.

Description

As arguments, SBGP takes the local AS number followed by the IP
address and AS number of the BGP4 peer. Multiple peer IP addresses

and

AS pairs may be specified. For example:

sbgp AS2011 enss131.t3.ans.net AS690

attempts to initiate a BGP4 peering session with the old NSFNET
backone on enss131. By default, SBGP writes logging information to
/tmp/bgp.log.

The following command directs tracing information to stdout (the -v option) and will save MRT messages containing the contents of BPG4
update packets to /tmp/data (the -o option).

sbgp -vo data AS2011 enss131.t3.ans.net AS690

Note that the remote peer must be configured to accept a BGP4 peer

ing

session from the machine on which SBGP is running.

The following command will inject routes stored in the binary MRT
message file data into the peering sessions with enss131:

sbgp -vi data AS185 enss131.t3.and.net AS690
