DGateway/bridge management interface. This interface is used as a bridge host interface or gateway interface depending on the operation mode. In this manual it is called VBRIDGE. On the M1122 web pages, the interface is called gateway or bridge IP interface.

M1122 can operate in four different main modes:

DBridging only

DRouting/tunneling IP only

DRouting/tunneling IP, bridging all but IP

DRouting/tunneling IP and bridging all, including IP

The mode in which M1122 operates depends on the configuration of the unit’s interfaces.

LAN interface

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

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

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

DBridging 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.

Internal host/gateway interface

There is a special host/gateway logical IP interface within M1122 called VBRIDGE. This interface has a specific purpose in M1122. In applications where some ATM virtual channel connections are used for bridging IP traffic and some other ATM virtual channel connections are used for routing IP traffic, the VBRIDGE interface must be used instead of LAN IP addresses. Alternatively, this interface is used in bridge only application when the IP address is required for remote management purposes.

Data VCC operation

M1122 supports the following encapsulations in each ATM data virtual channel individually:

DRFC2684 LLC encapsulation for bridged IP (ETH-LLC)

DRFC2684 LLC encapsulation for routed IP (IP-LLC)
