Configuring Inverse ARP for Data PVCs

You can use the inarp command in ATM VC Configuration mode to enable Inverse ARP (InARP) on a data PVC that resides on an ATM 1483 NBMA subinterface configured with the multipoint option. The PVC must use the default encapsulation method, aal5snap. For more information about InARP, see Configuring an NBMA Interface.

For example, the following commands enable InARP with a nondefault refresh rate (10 minutes) on a data PVC. The PVC uses aal5snap encapsulation by default. Issuing the exit command causes the configuration to take effect.



host1(config)#interface atm 3/2.1 multipoint 

host1(config-subif)#pvc 6 0/11 

host1(config-subif-atm-vc)#inarp 10 

host1(config-subif-atm-vc)#exit 

host1(config-subif)#

inarp

Use to enable Inverse ARP on an ATM PVC that resides on an ATM 1483 NBMA subinterface and uses the default encapsulation method, aal5snap.
You can optionally specify an Inverse ARP refresh rate, in the range 1–60 minutes; the default value is 15.
You must issue the exit command from ATM VC Configuration mode for the configuration to take effect.
Examplehost1(config-subif-atm-vc)#inarp 5 host1(config-subif-atm-vc)#exit
Use the no version to restore the default behavior, which disables Inverse ARP on the router.
See inarp.
