LAN interface

Vbridge
(gateway/host inter-
face)

ATM VCC interfaces

Route/tunnel IP, bridge all other traffic

Routing (IP address
configured) and bridg-
ing activated.

VCCs that only route
or tunnel have routing
(IP address confi-
gured) or PPTP local
tunneling activated.

VCCs that both bridge
and route have addi-
tionally bridging acti-
vated. This requires
ETH-LLC encapsula-
tion to be used on
those VCCs.

VCCs that only bridge
have only bridging
activated.

Typically not used in
this case. The unit
can be managed lo-
cally through LAN in-
terface and remotely
through a separate
management VCC or
the ATM VCCs which
have routing acti-
vated.

Route/tunnel IP, bridge all other including IP

Bridging activated

VCCs that only route
or tunnel have routing
(IP address confi-
gured) or PPTP local
tunneling activated.

VCCs that only bridge
have only bridging
activated.

Used as an IP gate-
way interface for LAN
interface.

Operational modes

LAN interfaces

LAN interfaces can be configured individually to bridge and route
packets. There are three different operational modes in LAN
interfaces:

D

Bridging only; only bridging is activated in the interface. In this
case the interface bridges all protocols.

D

Routing only; only IP address is configured in the interface. In this
case, the interface routes IP packets.

D

Bridging and routing; Bridging is activated in the interface and IP
address is configured in the interface. In this case, the interface
routes IP packets and bridges all other packets.
