Configuring IPoA
To configure IPoA on a PVC for it to carry IP packets:
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.
map ip { ip-address | default |
inarp [ minutes ] } [ broadcast ]
By default, no IPoA mapping is
configured. If a mapping is
configured, pseudo-broadcast is
not supported by default.
NOTE:
•
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/multicast packets or enable broadcast/multicast on an ATM PVC,
you must specify the broadcast keyword.
• On PVCs created on P2P ATM subinterfaces, you must configure the map ip default broadcast
command.
Configuring IPoEoA
IPoEoA enables a PVC to carry Layer 3 Ethernet packets.
To configure IPoEoA on a PVC:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a Layer 3 virtual
Ethernet (VE) interface.
interface virtual-ethernet
interface-number
Assign an IP address to the VE
interface rather than the ATM
interface. The IP address assigned
to the ATM interface is invalid for
IPoEoA.
3. Return to system view. quit N/A
4. Enter ATM interface view.
interface atm { interface-number |
interface-number.subnumber }
N/A
5. Enable packet padding on the
interface.
eoapad enable
Optional.
Disabled by default.
6. Create a PVC and enter its
view.
pvc { pvc-name [ vpi/vci ] |
vpi/vci }
N/A
7. Configure an IPoEoA
mapping on the PVC.
map bridge virtual-ethernet
interface-number No IPoEoA mapping is configured
by default.
