HP ProCurve 2910al Switch User Manual

IP Routing Features
Configuring IP Parameters for Routing Switches
Note A less common type, the all-subnets broadcast, goes to all directly-attached
subnets. Forwarding for this broadcast type also is supported, but most
networks use IP multicasting instead of all-subnet broadcasting.
Forwarding for all types of IP directed broadcasts is disabled by default. You
can enable forwarding for all types if needed. You cannot enable forwarding
for specific broadcast types.
To enable forwarding of IP directed broadcasts, enter the following CLI
command:
ProCurve(config)# ip directed-broadcast
Syntax: [no] ip directed-broadcast
ProCurve software makes the forwarding decision based on the routing
switch's knowledge of the destination network prefix. Routers cannot deter-
mine that a message is unicast or directed broadcast apart from the destina-
tion network prefix. The decision to forward or not forward the message is by
definition only possible in the last-hop router.
To disable the directed broadcasts, enter the following CLI command:
ProCurve(config)# no ip directed-broadcast
