hi;
as the author of pyrt, i'd just like to say that extending it to act =20
as a bgp speaker able to read an MRTD file in and push it out down a =20
peering as a series of updates ought indeed to be straightforward. =20
it used to be able to read routeviews and ris BGP update and rib =20
dumps ca. 2001/2002 as i used them for testing before we got the live =20=
feeds from sprintlink setup; it's possible that new attributes and =20
suchlike might mean that it has problems with current dumps, but that =20=
ought to be similarly easy to fix. let me know if you run into any =20
problems with pyrt and i'll see what i can do to help!
(i'm just pleased that someone might still want to use the code :)
Cheers,
