Abhi, It is not as much a question about filtering prefixes, it is more a question of why your network would originate 206.108.255.0/24 Jeremy Lumby Minnesota VoIP 9217 17th Ave S #216 Bloomington, MN 55425 M: 612-355-7740 D: 612-392-6814 F: 952-873-7425 jlumby@mnvoip.com From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Abhi Devireddy Sent: Monday, March 30, 2020 5:29 PM To: MICE-DISCUSS@LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] BGP alerts about AS 53740 (OPTBIT) Frank, That's really interesting. I'm sending QRator an unfiltered BGP feed and that might be triggering the error(?). I'll try to filter my feed to QRator to deny the MICE prefix and see if that fixes it. Open to suggestions as well.

Are they suggesting OPTBIT is advertising MICE’s /24? I’ve seen this come and go since Sunday night at 10:09 pm Central.
