| This chapter presents background and configuration information for transparent bridging and related bridge functions. -
4-1: Transparent Bridging -
4-2: Concurrent Routing and Bridging (CRB) -
4-3: Integrated Routing and Bridging (IRB) The router can bridge protocols using one of three methods. Table 4-1 provides a brief comparison of these methods . Table 4-1. Bridging Comparisons | Bridging Method | Description | | Transparent bridging | Allows interfaces within a specified bridge group to bridge all traffic that the router is not configured to route between interfaces in the group . | | Concurrent Routing and Bridging | Allows you to bridge a specific protocol on some interfaces while routing it on others. | | Integrated Routing and Bridging | Allows you to route and bridge for a given protocol on interfaces in the same bridge group. | |
