Advanced Bridging Options 5-9
In general, a packet received in a routed encapsulation (i.e., IPCP or
routed RFC 1483 or RFC 1490) is delivered to the router. A packet
received in a bridged encapsulation is passed to the bridge. If
MAC-Encapsulated Routing is enabled, the received
(bridge-encapsulated) packets are delivered to the router.
Advanced Bridging
Options
The advanced bridging configuration options are located with the rest of
the Local Site configuration options. However, these advanced bridging
options function more as global parameters and therefore are applicable
to bridging over the WAN as well as the LAN.
Most users do not need to change these values from the defaults.
To alter advanced bridging configurations:
1 Go to the OfficeConnect Remote 840 home page and select
Configuration > Local Site > Bridge .
2 Click Advanced to access a screen containing the following field:
You may then enter the following fields:
■
Aging Time — Time (seconds) for aging out forwarding table
information.
■
Forward Delay — Time (seconds) to wait while learning forwarding
information before starting to bridge packets.
■
Spanning Tree Priority — Priority of this spanning tree node. This is
used for prioritizing the nodes when spanning tree is enabled (which
is determined on either the Bridge Add or Bridge Modify/Delete
screens).
