Introduction

This document provides a sample configuration for reverse Synchronous Data Logical Link Control (SDLLC) with remote source-route bridging (RSRB) for Ethernet.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Configure

This section presents you with the information you can use in order to configure the features this document describes.

Note:  Refer to the Command Lookup Tool ( registered customers only) to find additional information on the commands this document uses.

Configurations

This document uses these configurations:

Router A

bridge 4 protocol ieee 
source-bridge ring-group 100 
source-bridge remote-peer 100 tcp1.0.0.1 
source-bridge remote-peer 100 tcp 5.0.0.1
 
interface serial 0 
encapsulation sdlc-secondary 
sdlc address c1 
sdllc traddr 0110.2222.3300 222 1 100 
sdllc partner 4000.0122.0001 c1 

interface loopback 0 
ip address 1.0.0.1 255.255.255.0

Router B

source-bridge ring group 100 
source-bridge remote-peer 100 tcp 1.0.0.1 
source-bridge remote-peer 100 tcp 5.0.0.1 
source-bridge transparent 100 13 1 4 

interface ethernet 0 
ip address 5.0.0.1 255.255.255.0 
bridge-group 4 

bridge 4 protocol ieee

The MAC address on the Ethernet (canonical) is in the Least Significant Bit (LSB) first and the Token Ring (non-canonical) is in Most Significant Bit (MSB) first. This means that the "traddr" address (non-canonical) must be the bitswapped version of the address in the host. Also, the partner address must be the bitswapped version of the Ethernet MAC address of the host.

0200.8044.0080 is the bitswapped form of 4000.0122.0001.

Notes:

  • This works for a PU 2.0 session only.

  • Requires exchange identification (XID) from a LAN-attached device in order to initiate a session.

  • IP routing and WAN configurations are not shown in this document for simplicity. However, they are required.

  • Clocking is required by the DCE device (not shown in these configurations) on the serial interfaces.

Verify

There is currently no verification procedure available for this configuration.

Troubleshoot

There is currently no specific troubleshooting information available for this configuration.
