Configuring A Broadcast; Configuring Inverse Arp - Cisco 10000 Series Configuration Manual

Commands
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

To configure broadcast packet duplication and transmission for an ATM PVC or VC class, use the
broadcast command.
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 broadcast
Note
command. See the
protocol ip command.
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).
The following example shows how to use the broadcast command to restore the default behavior:
Router(config)# interface atm 5/0/0.4
Router(config-subif)# pvc 0/105
Router(config-if-atm-vc)# broadcast
Router(config-if-atm-vc)#

Configuring Inverse ARP

To configure the Inverse ARP time period for an ATM PVC or VC class, use the inarp command in
interface-ATM-VC configuration mode or VC-class configuration mode.
inarp minutes
no inarp minutes
Where minutes is the Inverse ARP frequency from 1 to 60 minutes.
The default frequency is 15 minutes.
Use the no form of this command to restore the default Inverse ARP time period behavior.
