NANOG 17 Peering BOF Meeting Notes

Hi all -

I want to thank all of you who participated in the Peering BOF Monday night
at the last NANOG meeting in Montreal. It was lively and very productive.
To document the BOF, and for the benefit of those who could not attend
NANOG, I am sending out my BOF meeting notes. Comments/Corrections welcome.

As an aside, I'd like to thank my old colleagues at Merit for inviting me
to return to the stage and MC the Montreal NANOG. It was a lot of fun -
Thanks!

Hope these notes help. Cheers -

Bill

In regards to the snipet from the BOF notes below, is there any sort of
prepackaged method to collect and analyze the data regarding traffic flow
and the originating AS? (i.e. Some software that does this, or a Cisco
command that I'm not familiar with yet?)

ip cef accounting per-prefix

will create a summary of bytes per prefix (which you can see with "show ip cef
detail" )... you'll have to parse this against the routing table to get
originating AS.

NOTE (big note) ... I have no clue as to how this will affect router performance
and strongly suspect that it will be somewhat debilitating.
