Every time IANA allocates new prefixes, we're treated to complaints about sites that are not reachable because they're in the new space and some places haven't updated their bogon filters. My question is this: have we reached a point where the bogon filters are causing more pain than they're worth?
Perhaps operators can be convinced that the only best practice implementation of bogon filtering is through the use of a well maintained bogon route server service, be it from Team Cymru or some other well regarded 3rd party. All static, manual config management of bogon routes should be strongly discouraged. Now if router vendors could figure out ways to use a bogon route server for multicast protocols, that would be of a great help to niche community that has to run that service. There the pain is arguably worth it (dig about multicast being painful with or without them here :-) John
