IP Routing
The DSL router uses destination-based routing for downstream traffic. An IP
Routing Table is maintained to specify how to forward IP datagrams downstream.
The DSL router is capable of supporting 32 entries in the IP Routing Table. This
table can be viewed by both Operator and Administrator access levels.
The DSL router uses source-based forwarding for upstream traffic to ensure that
packets are forwarded to the upstream router specified for the configured Service
Domain.
Refer to Chapter 4, DSL Router Configuration Examples , for further details.

environments. The following sections provide descriptions of some of the DSL
