Configuring Source-Route Bridging

This chapter describes source-route bridging (SRB) configuration tasks. For a discussion of remote source-route bridging (RSRB) configuration tasks, refer to the “Configuring Remote Source-Route Bridging” chapter in this publication.

For a complete description of the SRB commands mentioned in this chapter, refer to the “Source-Route Bridging Commands” chapter in the Bridging and IBM Networking Command Reference. To locate documentation of other commands that appear in this chapter, use the command reference master index or search online.

SRB Configuration Task List

Perform the tasks in the following sections to configure SRB:

•

•

•

•

•

•

•

•

•

Configure Source-Route Bridging

Configure Bridging of Routed Protocols

Configure Translation between SRB and Transparent Bridging Environments

Configure NetBIOS Support

Configure LNM Support

Secure the SRB Network

Tune the SRB Network

Establish SRB Interoperability with Specific Token Ring Implementations

Monitor and Maintain the SRB Network

See the end of this chapter for “SRB Configuration Examples.”

Warning The Cisco IOS software issues a warning if a duplicate bridge definition exists in a router. You must remove an old bridge definition before adding a new bridge definition to a router configuration.
