Here's what I see: BGP routing table entry for 199.212.134.0/24, version 5658446 Paths: (3 available, best #2, table Default-IP-Routing-Table) Advertised to peer-groups: tn-core 18984 3561 852 11647 216.182.0.33 (metric 2965760) from 216.182.0.33 (216.182.0.33) Origin IGP, localpref 100, valid, internal Community: 233373696 1244135434 1239 852 11647 144.228.242.224 from 144.228.242.224 (144.228.242.224) Origin IGP, localpref 100, valid, external, best 1239 852 11647, (received-only) 144.228.242.224 from 144.228.242.224 (144.228.242.224) Origin IGP, metric 49, localpref 100, valid, external core1-nwtnj#trace 199.212.134.9 Type escape sequence to abort.

I see the announcement from Sprint with an AS path of 1239 852 11647, but it never gets past one of the routers on Sprint's network. I have no problem going through Cable and Wireless: Type escape sequence to abort.
