Last year I built my self an Cisco/Foundry BGP config to RPSL generator
to create RPSL for in an routing registry (I primarily use the RIPE
database). I did this because there where only tools that could do the
other way around, generate a config from your RPSL entries in the
routing registry database. As I currently can't find any tool in the
wild that can do this I'm hereby opening it to the world.
It's written in perl and is focused on the RIPEdb. It can be found
here. It has some examples incorporated for it.
It currently defines it preference and as-set we announce by
peer-groups in the router config. I was busy rebuilding it so it can
figure this out by it self and only needs the router config to be fed
by stdin and automatically find out which AS-SET is being used and
which preferences and metrics are going to be used.
Feedback is very welcome as well are updates, patches and bugreports.
There is still a little todo list to add to the script which includes
communities and metrics.
Notice that it only builds import/export and remarks line, the rest of the aut-num object has to be build around it.
Update: Version
20041127-2.pl
has been released. This version incorporates automatic localpref,
metric and community setting in the rpsl object. Unfortunately AS
prepending does not work. The
RFC2622 describes it, but the RIPEdb (which I test on) does not accept it.
The next step for updaterpsl.pl will be automated local interface
detection. In the far future also announcements can be auto generated
from the configuration. Currently this is hardcoded in the file.
Update: I just found a tool that does about the same but is less portable because it relies on SNMP to do the trick. You can find it
here
