ip multicast-arp-learning

Use this command to remove the multicast ARP learning restriction on an interface.

Syntax

ip multicast-arp-learning
no ip multicast-arp-learning

Parameters

None.

Defaults

None.

Mode

Configuration command, Interface configuration command mode.

Usage

As specified in RFC 1812, by default the router must not believe any ARP packet that claims the packet MAC address is broadcast or multicast. Use this command to remove the multicast restriction. The broadcast restriction remains unchanged.

The “no” form of this command reinstates the multicast restriction for ARP packets.

Example

This example shows how to remove the multicast restriction for ARP packets:

System(rw-config)->interface vlan 1
System(rw-config-intf-vlan.0.1)->ip multicast-arp-learning
