SRB with Automatic Spanning-Tree Function Configuration Example
Configuring Source-Route Bridging BC-147
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.
