SRB with Automatic Spanning-Tree Function Configuration Example

The following example of a Cisco series 7000 router configuration illustrates how to enable the automatic spanning tree function on an SRB network:

source-bridge ring-group 100

interface tokenring 0/0 no ip address ring-speed 16 multiring all source-bridge active 1 10 100 source-bridge spanning 1

!

interface tokenring 0/1 no ip address ring-speed 16 multiring all source-bridge active 2 10 100 source-bridge spanning 1

!

bridge 1 protocol ibm

Optimized Explorer Processing Configuration Example

The following configuration example improves the handling of explorer frames, enabling the Cisco IOS software to perform substantially better during explorer broadcast storms. In this configuration, the maximum byte rate of explorers is set to 100000.

source-bridge explorer-maxrate 100000 source-bridge explorerQ-depth 100

no source-bridge explorer-fastswitch

SRB-Only Example

The following example shows that all protocols are bridged, including IP. Because IP is being bridged, the system has only one IP address.

no ip routing
