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
peering
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
