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.

ATM VCC interfaces
Route/tunnel IP, bridge all other traffic
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.
Route/tunnel IP, bridge all other including IP
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.

Vbridge
(gateway/host inter-
face)
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.
Used as an IP gate-
way interface for LAN
interface.
