In standalone Babel (untested):

  out if eth42 ip 0.0.0.0/0 deny

(The part between "out" and "deny" is a list of keyword/value pairs, so
it should be read as "when if=eth42 and ip is in 0.0.0.0/0".)

In Quagga (untested):

  access-list no-ipv4 deny any

  router babel
    distribute-list no-ipv4 out eth42
