Dear Valdis; If you mean AS 1312 VA-TECH-AS , we see 4 routes : * 63.164.28.0/22 160.81.38.225 9 0 1239 7066 1312 i * 166.61.8.89 0 145 11537 7066 1312 i * 157.130.46.53 300 701 1239 7066 1312 i *> 216.177.55.5 500 15076 1239 7066 1312 i * 128.173.0.0 157.130.46.53 300 701 1239 7066 1312 i * 166.61.8.89 0 145 11537 7066 1312 i *> 216.177.55.5 500 15076 1239 7066 1312 i * 160.81.38.225 9 0 1239 7066 1312 i * 192.70.187.0 157.130.46.53 300 701 1239 7066 1312 i * 166.61.8.89 0 145 11537 7066 1312 i *> 216.177.55.5 500 15076 1239 7066 1312 i * 160.81.38.225 9 0 1239 7066 1312 i * 198.82.0.0/16 157.130.46.53 300 701 1239 7066 1312 i * 166.61.8.89 0 145 11537 7066 1312 i *> 216.177.55.5 500 15076 1239 7066 1312 i * 160.81.38.225 9 0 1239 7066 1312 i If you mean AS 13546 VT-RICHMOND-AS, only one in BGP from AS 16517 : 208.16.73.0/24 In MBGP, we only see two of these routes. Two others are aggregated into Sprint address blocks : 63.164.28.0 208.16.73.0 while 192.70.187.0 does not appear at all and is not MBGP routable from us.
