Hi,
On the 5th we notice that 27048 was announcing 2 of ours /24
812 3549 209 721 27064 27047 27047 27047 27048
maybe 721 doesn't have prefix AND as-path filters? (or 209 maybe?) or intentional filtering gone wrong :(
It lasted about 9h but didn't impact anything due to its prepend and such...
My inquiry is:
. False positive? . Broken 16b <=> 32b ASN's? . Human Error? . I should remove my Echelon triggering keywords from my personal .sig? ( 27048 is part of a US DoD ASN range =D ).
I check around and it happened a few times in the past. ( I saw a CIDR report in 2008 where 27048 was announcing 8m+ IP's )
Let me know.
