Thanks Vinny.... The ce I'm tracing from is talking ospf with it's directly connected pe.
Also, last hop 10.101.18.2 is a directly connected ce device hanging off of last hop PE (10.101.1.6). path back from that ce device 10.101.18.2 is a def route from it. Still not seeing how/why this strange AS number would show up like this.

Since 65111 is a private AS, your CE is likely configured with BGP talking to a PE router which is feeding you matching routes for each hop (or maybe just a simple default route) which is why that AS number shows on each hop. -Vinny -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Aaron Sent: Friday, April 20, 2012 2:56 PM To: [email protected] Subject: [c-nsp] L3VPN traceroute from ce--->vpn cloud---->ce What's the deal with the traceroute from CE (cisco device) via mpls l3vpn showing some strange AS number ?
