Configuring the Pipeline as a Bridge

Managing the bridge table

Pipeline User’s Guide Preliminary January 30, 1998 5-7

Managing the bridge table

To forward bridged packets to the right network destination, the Pipeline uses a

bridge table that associates end nodes with particular connections. It builds this

table dynamically, as described in “Transparent bridging” on page 5-7. It also

incorporates the entries found in its Bridge profiles. Bridge profiles are analogous

to static routes in a routing environment. You can define up to eight destination

nodes and their connection information in Bridge profiles.

Parameters that affect the bridge table

Parameters directly related to the bridge table are set in the following menus:

Ethernet

Mod Config

Ether options...

Bridging=Yes

Ethernet

Connections

profile

Bridge=Yes

Dial Brdcast=No

Ethernet

Bridge Adrs

Enet Adrs=CFD-12367

Net Adrs=10.0.0.12

Connection #=7

For details on each parameter, see the Reference Guide.

Transparent bridging

As a transparent (or learning) bridge, the Pipeline keeps track of where addresses

are located as it forwards packets. It records each packet’s source address in a

bridging table. A Connection profile is associated with an address when it is used

to dial the link or when it matches an incoming call.
