Source Routed Bridging (SRB) Mode

Note: SRT is the suggested mode of operation.
If multiple CRFs are used on a switch, all translational links to the same Ethernet
cloud should be grouped into one CRF. If a CRF is created in SRB Bridging mode
and spanning tree is to be used, IEEE STP must be manually configured on the BRF
and CRF.
Note that this translational CRF is used only on the Token Ring side and is used to
route source-routed Token Ring frames toward the Ethernet cloud.

Note: In this mode IEEE STP works on all SRT and SRB CRFs. For more
information, see the SmartStack STS16-20RM/STS16-20FRM Token Ring Switch
Installation and User Guide.
