Hi there, I just had a real quick question. I hope this is found to=
be on topic.
Is it to be expected to see rfc1918 src'd packets coming from transit carri=
ers?
We have filters in place on our edge (obviously) but should we be seeing tr=
affic from 192.168.0.0 and 10.0.0.0 et cetera hitting our transit interface=
s?
I guess I'm not sure why large carrier networks wouldn't simply filter this=
in their core?
Thanks,
-Drew
