CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1 Switch Overview
Figure 6. Source Route Transparent Bridging (SRT) Mode
Source Route Bridging (SRB)
➽
Note: SRT is the suggested mode of operation.
If multiple CRFs are used on a switch, all Fast Ethernet 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. See Figure 7.
