I try to speak about networks in general. I hope that many people on the
list understand peering and filtering.
For example. If I peer with any provider, from Sprint to the provider
sending me 1 route I will filter _701_ from all of them. I will also
filter _1239_ from _701_ and all other peers. Please be aware, that I used
the term PEER and not Transit provider.
I would filter the RFC1918 from peers and transit providers. I would
filter IANA-RESERVED. I would filter my own IP space (no reason to see
someone else deagg towards me)
People have emailed me privately about filtering and I have given some
examples of filtering.
At the end of Feb, Steve Meuse and I talked about filtering at the LINX
meeting. If people would have followed some of the information given, they
might not have had a problem when an internet provider leaked the linx IP
addresses
! LINX
access-list 1 deny 195.66.224.0
access-list 1 deny 195.66.225.0
Here is the URL if anyone would like to look at some of the filtering
Exodus does
