Hi there, is there any tools available under linux which can do bgp
traceroute? (print bgp AS numbers for each traceroute hop ) , i googled and
found nothing.
thanks
John
beyond awesome!
The traceroute variant included with CentOS 6.4 & Mint 13 has an -A flag which does ASN lookups. ntraceroute on FreeBSD supports it as well. I believe the Linux port is traceroute-nanog.

even the basic traceroute util with show AS with the -A flag. I actually
can't remember any of the tracing tools which don't support it, offhand.
Yep.
Tracepath is a nice tool as well
Indeed - while lft is not IPv6 enabled.

traceroute -A consults the internet routing registry which is know
to beincomplete and at times incorrect when it comes to IP to
BGP origin AS mapping. For this reason we developed riswhois.ripe.net,
a whois style interface to the BGP data collected by RIPE NCC's Routing
information service (http://www.ripe.net/data-tools/stats/ris)
Reporting in the same format as the IRR, riswhois is plugin
compatible with whois.radb.net. If your linux traceroutederives
from http://traceroute.sourceforge.net/ all it takes to switch to
using true BGP info in traceroute is setting the environment variable
RA_SERVER to "riswhois.ripe.net"

P.S. the LFT tool metioned earlier in this thread can also use RISwhois
to lookup ASNs; just pass it the -r option on the command line.
It would be slick if someone could patch mtr to do this too.
I agree, ASN lookup in mtr would be awesome! I'll have to look into that sometime.

It's in mtr as of v0.83.

Unfortunately not in winmtr.

Is there likely to be a scaling issue if everybody on NANOG does that?
Or what if a large(ish) Linux distro does that by default?
