Bridge Connection Setup

A pure bridged connection does not assign and IP address to the WAN interface. NAT and

firewall rules are not enabled. This connection method makes the RG act as a bridge for passing

packets between the WAN interface and the LAN interface.

To configure the 6381 as a bridge:

1.

From the

Home

page, click

Setup

and then click

New Connection

.

The default PPPoE connection setup is displayed.

2.

In the

Type

dropdown select

Bridge

The Bridge connection setup page is displayed.

3.

In the

Name

text box enter a unique name for the bridge

The name must not have spaces and cannot begin with numbers.

4.

Network Address Translation (

NAT

) and the

Firewall

options are enabled by default. Leave

these options enabled.

5.

In the

Bridge Settings

section, select the

Encapsulation

Type (

LLC

or

VC

) as supplied by

your ISP.

If you are unsure, just leave the default settings.

Encapsulation

The technique used by layered protocols in which a layer adds header information

to the protocol data unit (PDU) from the layer above. As an example, in Internet

terminology, a packet would contain a header from the data link layer, followed by

a header from the network layer (IP), followed by a header from the transport

layer (TCP), followed by the application protocol data. Two encapsulation options

are provided:

•

Logical Link Control (

LLC

)

•

Virtual Channel (

VC

).

Select LAN

Select the LAN group for the bridged connection. The following options are

available:

•

LAN Group 1

•

LAN Group 2

•

LAN Group 3

•

None

This bridged connection will be added to the selected LAN group. If you select

None, the connection is not added to any LAN group but to the Interfaces box on

the LAN Configuration page which can be configured to a LAN group on the same

page.

6.

In the

PVC Settings

section, enter values for

VPI

and

VCI

as supplied by your ISP

For more information, please see PVC Settings from the PPPoE Setup procedure.

7.

Select the quality of service (

QOS

).

Leave the default value if your ISP did not provide this information.

Depending on the QoS

you select, you may also enter:

•

PCR

(Peak Cell Rate)

•

SCR

(Sustainable Cell Rate)

•

MBS

(Maximum Burst Size)

•

CDVT

(Cell Delay Variation Tolerance)

CLIP Connection

Classical IP and ARP over ATM (CLIP) allow IP datagrams and ARP (Address Resolution

Protocol) requests and replies to be transmitted over ATM using ATM Adaptation Layer 5 (AAL5).

CLIP, defined in RFC 2225, provides the ability to transmit IP packets over an ATM network. The

6381’s CLIP support encapsulates an IP datagram in an AAL5 PDU frame using RFC 2225 and it

uses an ATM-aware version of the address resolution protocol (ATMARP). The 6381’s CLIP

support only allows support for PVCs; SVCs are not supported by the 6381 RG.

To configure a CLIP connection:

1.

From the

Home

page, click

Setup

and then click

New Connection

.

The default PPPoE connection setup is displayed.

2.

In the

Type

dropdown select

CLIP

The CLIP connection setup page is displayed.
