Configuring Bridging on a Router in Not-Forwarding Mode
Because the IP router does not forward IP traffic in not-forwarding mode, you
must configure the router to bridge IP traffic not explicitly addressed to it. You
must configure the bridge for each circuit that conveys IP datagrams. The bridge
will then forward all IP datagrams that are not explicitly addressed to the router.
For instructions on configuring bridging, see Configuring Bridging Services.
Table 3-1
and Table 3-2 show valid and invalid configurations for source routing
bridges and learning bridges. Each configuration has one of the following formats:
source_device > medium > destination_device
source_device > medium1 > intermediate_device > medium2 >
destination_device
