Configuring the DSL Router

Routed vs. Bridged PDUs
The DSL router supports both the VNET model and the 1483 Routed model
(derived from RFC 1483) for the transportation of PDUs (Protocol Data Units)
from the DSL router to the router in the core network. When operating in
Standard mode, the DSL router supports both routed and bridged PDUs. When
operating in VNET mode, the DSL router supports bridged PDUs only.
NOTE:
Standard mode vs. VNET mode is configured on the DSL card at the
DSLAM/GranDSLAM chassis.
Both ends of the network (e.g., the DSL router and the DSL line card or the core
router) must be configured to operate the same way (i.e., routed or bridged).
If Using This Network Model . . . Then These DSL Cards Can Be Used . . .
