Enabling All-Subnet Broadcasting on an Interface
An all-subnet broadcast (ASB) datagram has a destination address equal to the
broadcast address for an entire network (all subnets). For example, if a network
interface serves the subnet 128.10.2.1 with a subnet mask of 255.255.255.0, the IP
router considers any datagram with a destination address of 128.10.255.255 or
128.10.0.0 to be an ASB datagram.
By default, IP does not flood ASB datagrams. You can use the BCC or Site
Manager to turn this feature on and off as required.
Using the BCC
Navigate to an IP interface-specific prompt and enter:
all-subnet-broadcast
state
state is one of the following:
on
off
(default)
For example, the following command causes IP to flood ASB datagrams out
interface 2.2.2.2:
ip/2.2.2.2# all-subnet-broadcast on
ip/2.2.2.2#
