I am running full BGP tables from 4 different upstreams around, doing v4 and v6. The v6 full table is now around 400K and v6 some 20K plus a private peering session with around 200 routes. Doing this on a pair of cisco GSR with redundant route processors, and doing lot of complex filtering. CPU is doing good :)
