Er,

1) "Anycast" is something totally orthogonal, and the mere use of the
   particle "cast" in the word does not make it related.
2) Of course there is a direct equivalent to broadcast, which is
   multicast. If you really do need to reach "everyone" you broadcast
   to the all nodes multicast address. No protocols that I know of
   actually need this in practice.
