Just wondering how far everyone is going on filtering BGP sessions when pee=
ring with other content providers and carriers over an internet exchange.
What are you doing.
1. Just filtering out IPv4 Reserved Space, RFC 1918, and Default Route=
s.
2. AS Path Filtering. Only filtering by the AS's that are present in t=
he IRR Record.
3. Filtering by IP Prefix based on the IRR Record for the Peer. (Yes s=
ome Prefix Filter list can be a couple thousand lines)
4. Doing both #3 and 4 listed above.
Besides Peering DB is there any software to help keep track of IX and Peeri=
ng info. So far I have only found IXP-MANGER
