I'm not setting it on my router locally but sending it over to Cogent as
a community string per page 22 of their user guide.

They use it to manipulate how traffic gets back to me so that is
incoming from my routers view.
I also pad the AS for the networks that I prefer to come back through
the other ISP..

Hi Vlade,
Well, if you are trying to balance the incoming traffic load with local-pref
attribute, I can understand your disappointment :)
Since it doesn't work at all this way: local-pref is local to an AS and deals
with outgoing traffic only.
B) We have our own AS and IP space. I advertise them to both Cogent and our
other ISP. I use the local preference attribute to share the load for incoming
traffic between both ISPs. In the last 5 outages over the last few years, this
has happened twice. I'm waiting on the RFO so I can further investigate why
this happened. I think someone mentioned this in a post a few months ago too.
