BGP routing table entry for 103.216.190.0/23, version 55444827

Paths: (42 available, best #37, table default)

  8283 3356

    94.142.247.3 from 94.142.247.3 (94.142.247.3)

      Origin IGP, metric 0, localpref 100, valid, external

      Community: 8283:1

      unknown transitive attribute: flag 0xE0 type 0x20 length 0xC

        value 0000 205B 0000 0000 0000 0001

      rx pathid: 0, tx pathid: 0

says it goes to ASN3356, according to RADB says that's level3.

Maybe its something wrong with your config, ip address, or your upstream
filtering (AS-SETS) and Prefix filtering etc.
