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.
