or ignore/block russia and north korea and china network blocks takes away 5% of network ranges for memory headroom, especially the large number of smaller china blocks. Some may say this is harsh but is the network contacts refuse to co-operate with abuse and 100% of the traffic is bad then why not Colin

With BGP-SD, you can hold millions of entries in RAM, but decide what gets downloaded into the FIB. By doing this, you can still export a full BGP table to customers directly connected to your 6500, and only have a 0/0 + ::/0 (and some more customer routes) in the FIB to do forwarding to a bigger box. BGP-SD started shipping in IOS XE, but I now understand that the feature is on anything running IOS 15. This would be my recommendation. Mark.
