I'm trying to collect statistics on how many routes match certain patterns. So far I've been using zebra, set term len 0, and then sh ip bgp regexp, and wait for the total prefixes count at the end of the list. I figure there must be a better way than this, but so far haven't found one. Any ideas? Ralph Doncaster principal, IStop.com div. of Doncaster Consulting Inc.

Zebra supports dumping the RIB to MRT binary format. See the 'dump bgp' family of commands. I find this format much easier to deal with than CLI output. Bradley

I've been told getting the MRT sources to build is rather difficult. I may give it a shot anyway... -Ralph

Yeah I haven't been able to build directly from the MRT source recently. On FreeBSD building from the ports tree works fine. On Linux SuSE has an RPM at ftp://ftp.suse.com/pub/suse/i386/7.3/suse/n3/mrt.rpm that works on Linux flavors. Bradley
You could rebuild the source rpm to any flavour also. /Dee -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Bradley Dunn Sent: Monday, May 20, 2002 9:47 AM To: Ralph Doncaster Cc: nanog@merit.edu Subject: Re: route statistics

Compile zebra with --enable-snmp (the Debian binary package just switched on this option) and snmpwalk the BGP table (1.3.6.1.2.1.15 == mib-2.15, see RFC 1657) ? I didn't benchmark the two solutions against each other. If the BGP machine is an actual forwarding router, not just a dedicated looking glass, be sure to look at its load, not just at the wall-clock response time. Another solution is to dump the routing table <URL:http://manticore.2y.net/doc/zebra/bgpd.html#Dump BGP packet and table> in MRT format and to use MRT tools to analyze it (I tried that and at least the Python version of these tools is hopelessly broken).
