302CHAPTER 19: ATM CONFIGURATION COMMANDS

PVC so long as a next-hop address in the specified network segment is found for the packet.

default: A mapping with the default route property is set. If a packet cannot find a mapping with the same address of next hop at the interface, but one PVC has the default mapping, the packet can be sent over the PVC.

inarp: Enables inverse address resolution protocol (InARP) on PVC.

minutes: Time interval to send InARP packets, in minutes. The value ranges from 1 to 600 and defaults to 15 minutes.

broadcast: Enables pseudo-broadcast. If a map of the PVC is configured with pseudo-broadcast, the device sends on the PVC a copy of each broadcast or multicast packet that it sends out the interface to which the PVC belongs.

You must configure the broadcast keyword on an ATM PVC where broadcast or multicast packets must be sent, for example, to allow PIM multicast to create neighbor relationship with the router connected using the ATM interface.

Description Use the map ip command to create IPoA mapping for PVC.

Use the undo map ip command to delete the mapping.

By default, no mapping is configured. If a mapping is configured, pseudo-broadcast is not supported by default.

Before configuring InARP, make sure the aal5snap encapsulation is used. InARP is not supported when using aal5mux or aal5nlpid encapsulations.

Example # Create a static mapping on PVC 1/32, specifying the opposite IP address to 61.123.30.169 and supporting pseudo-broadcast.

<Sysname> system-view

[Sysname] interface atm 1/0

[Sysname-Atm1/0] pvc 1/32

[Sysname-atm-pvc-Atm1/0-1/32] map ip 61.123.30.169 broadcast

# Enable InARP on PVC 1/33 and send InARP packets every 10 minutes.

<Sysname> system-view

[Sysname] interface atm 1/0

[Sysname-Atm1/0] pvc 1/33

[Sysname-atm-pvc-Atm1/0-1/33] map ip inarp 10
