Configuring IPX RIP and
SAP
IPX RIP is used to exchange IPX routing information with other IPX routers. SAP is a
protocol used by IPX servers and routers to exchange information about the
location of servers.
protocol used by IPX servers and routers to exchange information about the
location of servers.
For IPX networks over the LAN you can separately enable or disable RIP and SAP.
When enabled you can also specify whether RIPs or SAPs are sent, received, or
both.
When enabled you can also specify whether RIPs or SAPs are sent, received, or
both.
To configure RIP for a LAN network, use the command:
set ipx network <network name>
rip [BOTH | DISABLE | LISTEN | RESPOND_ONLY | SEND]
To configure SAP for a LAN network use the command:
set ipx network <network name>
sap [BOTH | DISABLE | LISTEN | RESPOND_ONLY | SEND]
Other permutations of the set ipx network command can be used to configure
advanced RIP features and policies.
advanced RIP features and policies.
IPX RIP and SAP can be enabled or disabled for each remote site connection.
You cannot individually enable or disable RIP or SAP; they are enabled or disabled
together for each remote site connection. You can configure whether the
OCR 812 should advertise local routes and services, only listen for routes and
services from the remote site, or both.

Bridging
A bridge connects two or more physical networks together to function as one big
network. The OCR 812 can be configured to be a learning bridge. A learning
bridge does more than just link networks; it separates network traffic and
forwards only the packets that need to be forwarded.

bridge does more than just link networks; it separates network traffic and
forwards only the packets that need to be forwarded.
Bridges separate traffic by examining the Media Access Control (MAC) addresses
contained in data packets. MAC addresses uniquely identify each machine
attached to a network segment. A data packet is not forwarded to another
segment if its destination MAC address resides on the same segment as its source.
contained in data packets. MAC addresses uniquely identify each machine
attached to a network segment. A data packet is not forwarded to another
segment if its destination MAC address resides on the same segment as its source.
To efficiently separate traffic, the bridge maintains a Bridge Forwarding Table. The
table contains a list of MAC addresses and their associated network segments. The
table is built dynamically from the source MAC addresses of data packets passing
through the bridge.
