BGP and traceroute

[oneciscokid]

I've been trying to use traceroute on my router to see which path packets take, but would like to know if the AS numbers could be shown as well. I've checked out a Looking Glass and am wondering how can I do the same thing on my router? Is it only on specific IOS versions?

Something like

sl-bb20-sea-9-0.sprintlink.net (144.232.6.153) [AS 1239] 56 msec

Thanks.

Hi,

It must be, im running version 12.2(17) and traceroute shows AS numbers

2 172.16.199.2 [AS 2856] 12 msec * 8 msec

maybe the router has to have BGP running to show the AS numbers, I have routers not running BGP and they traceroute over the MPLS without showing the AS Numbers.

Be interested to find out.

I believe you need BGP running to see AS information. I assume that you also need to have it peering with something to get this info. I have not tried to just turn it on and see how it operates w/o a peering.
