What is ip broadcast-address 0.0.0.0 for?

Question

Cisco

Good afternoon.
I met such a setting CISCO 871
!
interface Vlan1
description Vlan 1
ip address 10.10.10.1 255.255.255.0
ip broadcast-address 0.0.0.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip nat inside
ip virtual-reassembly
ip route-cache flow
ip tcp adjust-mss 1452
!
Everything is clear, except for ip broadcast-address 0.0.0.0
Why?!
