R3102-R3103-HP 6600/HSR6600 Routers Layer 2 - WAN Configuration Guide

Step Command Remarks
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 that aal5snap encapsulation
is used. InARP is not supported
when aal5mux or aal5nlpid
encapsulations is adopted.
Configuring IPoEoA
When you configure IPoEoA, follow these guidelines:
• Pad PVC-carried Ethernet frames smaller than 60 bytes to 60 bytes on ATM interfaces. Ethernet
frames smaller than 60 bytes will be discarded by Ethernet interfaces.
• When multiple Layer 3 VE interfaces are connected through PVCs to a DHCP server that assigns IP
addresses to the interfaces through static address binding, configure different MAC addresses for
the interfaces by using the mac-address command.
• In an IPoEoA application, Class Based Queuing (CBQ) should be configured on PVCs.
• You can configure PVC mapping in PVC view. For information about the configuration, see MPLS
Configuration Guide.
To configure IPoEoA on a PVC:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Create a virtual Ethernet (VE)
interface.
interface virtual-ethernet
interface-number
Configure the IP address on a VE
interface. It is invalid to configure
the IP address on the ATM
interface.
3. Set the expected bandwidth
for the interface.
bandwidth bandwidth-value Optional.
4. Return to system view.
quit N/A
5. Enter ATM interface view.
interface atm { interface-number |
interface-number.subnumber }
N/A
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
N/A
Configuring PPPoA
When two routers are connected using DSL interfaces through a dial-up connection, configure them as
PPPoA server and client, respectively. The two are different in that: with the PPPoA server, configure an
address pool to allocate an IP address for the remote node; with the PPPoA client, configure address
