Configuring A Broadcast - Cisco 10000 Series Configuration Manual

ATM Commands
•
protocol ip {protocol-address | inarp} [[no] broadcast]
no protocol ip {protocol-address | inarp} [[no] broadcast]
Where:
•
•
•
Use the no form of this command to remove a static map or disable Inverse ARP.
Use the inarp command to configure Inverse ARP frequency.
Note
The following example shows how to specify IP protocol on an ATM PVC:
Router(config)# interface atm 5/0/0
Router(config-if)# pvc 0/105
Router(config-if-atm-vc)# protocol ip 172.16.32.49

Configuring a Broadcast

Use the broadcast command to configure broadcast packet duplication and transmission for an ATM
PVC or VC class.
The broadcast command is not used to enable ATM cell-level multicast, broadcast, replication, or to set
up the broadcast of user level traffic. The broadcast command indicates which PVC (or PVCs) sends
out broadcast traffic. This is typically limited to traffic associated with routing protocols and routing
updates (for example, OSPF hello packets).
The broadcast argument within the protocol ip command takes precedence over the
Note
broadcast command. See the
information.
Use the default form of this command to restore the default behavior described below.
broadcast
no broadcast
The default is broadcast.
Use the no form of this command to disable transmission of broadcast packets.
For PVCs created under point-to-point subinterfaces, broadcast is enabled by default. For PVCs created
under multipoint subinterfaces, you should use the broadcast command if you want to propagate IP
routes (only the first PVC on a multipoint interface receives broadcast traffic).

Enable Inverse ARP or Inverse ARP broadcasts on an ATM PVC by either configuring Inverse ARP
directly on the PVC or in a VC class (applies to IP protocols only).
protocol-address is the peer destination address that is being mapped to a PVC.
inarp (valid only for IP protocols on PVCs) enables Inverse ARP on an ATM PVC. If you specify
a protocol-address instead of inarp, Inverse ARP is automatically disabled for that protocol.
[no] broadcast (optional) indicates that this PVC sends out broadcast packets (for example, IGRP
updates). Pseudo broadcasting is supported. The broadcast keyword of the protocol ip command
takes precedence if you previously configured the broadcast command on the ATM PVC.
For PVCs created under point-to-point subinterfaces, broadcast is enabled by default. For PVCs
created under multipoint subinterfaces, use the broadcast argument to propagate IP routes.
