dependencies

• vtysh from the quagga package
• dot from the GraphViz package

usage

Run

vtysh -c 'show ip bgp' | vtysh_bgp_to_dot 1234 | dot -Tpng > graph.png

to generate a graph, where 1234 is your local AS and graph.png will be the generated graph. You need read-access with vtysh, of course.

optional features

If there is an info.conf in your current directory, it will be read to spice up the graph. The format of info.conf is whitespace delimited fields:

• First field contains an AS number.
• Second field contains a name describing the AS.
• Third field optionally contains a flag for marking a node in the output.

Example info.conf

60001  this_is_me
60002  Network_A
60003  Network_B  important
60004  Network_C

This configuration will add labels to the graph nodes 60001 to 60004 and mark the node 60003 as important.
