The RENATER I'm peering with is AS2200. From my PoV, AS1712 is announced by as174 and as701, with all the respect do to them I doubt their announcing RENATER. From what I receive from as2200: * 137.194.0.0 194.68.129.102 0 2200 2200 2422 1712 i And from bgp table (sniped): sh ip bgp path 1712$ Address Hash Refcount Metric Path 0x52D8F878 352 2 1001 174 1712 i 0x575A9088 1320 1 0 6453 174 1712 i 0x2274494C 1849 2 0 6453 701 1712 ? 0x52CF7AD0 1986 1 0 2200 2200 2422 1712 i 0x66B90AD0 3421 1 0 2200 2422 1712 i Indeed: WTF.
