Hello NANOG,
I noticed that more than 3K prefixes are with 2 Origin ASes.
Are they the simplest cases of anycast? Or they are mainly due to
misconfiguration?

The third (and probably more likely) option is that the prefixes are

Not disagreeing with you, just that SNMP write access is generally something
that admins keep either turned off or very, very tightly controlled. In that
context, how many devices (dslams, redbacks, etc) would have to
be touched via SNMP to turn off a customer (or customers) versus simply
As opposed to SNMP and a script that would shut the port down via SNMP
