====== BGP Replay Tool ====== Used to test BGP Route Receiver that ships with Trisul. 1. Download BRT from http://caia.swin.edu.au/tools/bgp/brt/downloads.html <note important> **mp_ methods** We are getting the following error with version 0.2 ''Can't locate object method "mp_unreach_nlri" via package "Net::BGP::Update" at brt-0.2.pl line 263, <$fh> line 2.'' As a hack you can comment out the mp_unreach_nlri and mp_reach_nlri , if you arent interested in multipath. There seems to be an issue with the Net::BGP module. </note> 2. Install the Perl Net::BGP module <code> sudo cpanm Net::BGP </code> 3. On router under test say it has AS 400 <code> sh bgp neighbors debug ip bgp all conf t router bgp 400 neighbor 192.168.3.100 remote-as 300 </code> 4. Download a route update file in MRT format. The easiest way is to download from a collector see http://archive.routeviews.org/ 5. Convert the MRT format update file to a format acceptable by brt using bgpdump BRT tool needs a human readable BGP update file '' BGP update file in human readable with Unix format (bgpdump -m option) '' Convert the file using bgpdump '' bgpdump -m updates.20191101.0130 > updates.20191101.0130.bgpdump '' 6. Now you can inject routes into the router table.
