Most use u_int now but esp. in pf(4) some of the u_int16_t are still around. Main problem with very large rtableids is that a simple array of pointers is used to get from the id to the routing table head so if you create one rtable with e.g. an id of 1'000'000 it will chew 8MB of memory on a 64bit system just for the lookup table. -- :wq Claudio
