Enabling an Interface to Receive and Forward Directed Broadcast Packets Destined for Its Direct Network Segment

Enabling an Interface to Receive and Forward Directed Broadcast Packets Destined for Its Direct Network Segment

Usage Scenario

A directed broadcast packet is broadcast to a specific network. In the destination IP address of such a packet, the network ID field contains the network ID of a specific network, and the host ID field contains all 1s.

Directed broadcast packets can be used by hackers to attack the network system, bringing security risks. However, the device interfaces may need to receive or forward directed broadcast packets in some scenarios. For example, when an interface is configured as a UDP helper, it converts broadcast packets into unicast packets and sends them to a specific server. To allow this, enable the interface to receive and forward directed broadcast packets destined for its direct network segment.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run ip forward-broadcast [ acl { acl-number | name acl-name } ]

    The interface is enabled to receive and forward directed broadcast packets destined for its direct network segment.

    By default, an interface is disabled from receiving or forwarding directed broadcast packets destined for its direct network segment.
