Well, you could add multiple arguments to functions.

Or you could add 'int set' argument to function:
export where f_main_ospf_e([RF_REDISTRIBUTE_CONNECTED, RF_REDISTRIBUTE_STATIC]);

Or could use specific functions for each type:
export where f_ospf_redistribute_connected() || f_ospf_redistribute_static();
