Hello; I sent a previous version of this message Friday morning to the admin contact for AS 1237, but I have as yet received no response. I am not sure if this is a real problem - I can still ping them - but it looks ugly to me. ------------------------------------------------------------------------------------- The BGP announcements for System Engineering Research Institute (SERI) (ASN-EUNSOL) R&D Net Group Eoeun-dong 1, Daejon KR Autonomous System Name: KREONET Autonomous System Number: 1237 appear to be misconfigured : *> 150.183.34.0/24 157.130.46.53 0 701 6453 1237 9270 1237 i etc. This is a routing loop; although it may work in practice, it is not a proper use of BGP and may not do what you intended. A list of all of the (many) affected address blocks follows.
