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.
