Configuring IPoA
When you configure IPoA, follow these guidelines:
If you execute the map ip command with the broadcast keyword, which specifies pseudo broadcast, any broadcast packets received by the port on which the PVC is created will be duplicated to the PVC. Therefore, to propagate broadcast or multicast packets on an ATM PVC with a broadcast or multicast protocol enabled, specify the broadcast keyword.
Configure the map ip default broadcast command on PVCs created on P2P ATM subinterfaces.
You can configure PVC mapping in PVC view. For more information, see HPE FlexNetwork MSR Router Series Comware 5 MPLS Configuration Guide.
To configure IPoA:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter ATM interface view. | interface atm { interface-number | interface-number.subnumber } | N/A |
3. Create a PVC, and enter PVC view. | pvc { pvc-name [ vpi/vci ] | vpi/vci } | N/A |
4. Configure an IPoA mapping for the PVC, and enable the PVC to carry IP packets. | map ip { ip-address [ ip-mask ] | default | inarp [ minutes ] } [ broadcast ] | By default, no mapping is configured. If a mapping is configured, pseudo-broadcast is not supported by default. Before configuring InARP, make sure aal5snap encapsulation is used. InARP is not supported when aal5mux or aal5nlpid encapsulations is adopted. |
