Bridging Capability
⇒
From the Remote Router Database menu screen, select Bridging
On/Off.
You specify whether the target router bridges traffic to/from this remote
router.
⇒
Click On or Off (default) to turn bridging on or off.
Spanning Tree Protocol (STP)
You can also specify if you wish the router to use the Spanning Tree
Protocol (STP) which allows the router to check for bridging loops and
communicate with other sites that support the protocol.
⇒
Select On or Off. Click OK to set the bridging parameters.
Default: The default behavior of the router is to NOT implement STP
when bridging over the ISDN WAN. This eliminates a period of about
40 seconds during which the ISDN lines are dialed and no user traffic is
forwarded, while the Spanning Tree Protocol checks for and eliminates
loops in the network topology.
On: If there is a possibility of redundant paths between nodes, the
Spanning Tree Protocol should be turned on when dialing a site where
such a loop possibility exists.
Off: If you choose to leave STP off, this assumes that no pair of nodes on
the larger network, made by joining all the local LANs that can dial each
other, can be connected by more than one path. This assumption usually
holds true for telecommuters and many branch office situations.
TCP/IP Route Addressing and IP Protocol Controls
TCP/IP Route Addresses
⇒
From the Remote Router Database menu screen, select TCP/IP
Route Addresses.
If you are configuring TCP/IP Routing, you now need to enter details
about routing to stations/networks on the LAN connected beyond the
remote router. Refer to the section Important Routing Concepts,
page 26 to determine if you need to seed the routing table and what
information is required.
