Parameter
acl-number: ACL in the range 1000 to 3999.
Description
Use the ip forward-broadcast command to enable the current interface to forward
broadcasts.
Use the undo ip forward-broadcast command to disable the current interface to
forward broadcasts.
By default, the router does not forward broadcasts.
You may configure this command on an output interface. When configured with an ACL,
the command which otherwise allows the output interface to forward all broadcasts
enables the output interface to forward only matched broadcasts.
Example
# Enable interface Ethernet 0/0/0 to forward all broadcasts.
[Router-Ethernet0/0/0] ip forward-broadcast
# Enable interface Ethernet 0/0/0 to forward broadcasts matching ACL 2100.
[Router-Ethernet0/0/0] ip forward-broadcast 2100
[Router] acl number 2100
[Router-acl-basic-2100] rule 1 permit source 1.1.0.0 0.0.255.255
[Router-acl-basic-2100] rule 2 deny source any
