3. Configuring the DSL Router
3-4 November 2003 6300-A2-GB20-10
IP Routing
Hotwire DSL Routers use destination-based routing for downstream traffic. An IP
Routing Table is maintained to specify how IP datagrams are forwarded
downstream. The DSL Router is capable of supporting static routes configured by
the user. 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 se rvice
domain.
Refer to Chapter 4, DSL Router Configuration Examples, for further details.
IP Options Processing
The DSL router handles and processes IP datagrams with options set as
described below. No command is available to set IP options.
The router does not process (and drops) any IP datagrams with the following IP
options:
Loose source and record route (type 131)
Strict source and record route (type 133)
Security (type 130)
Stream ID (type 136)
The router does process IP datagrams with the following IP options, but does not
provide its IP address or timestamp information in the response messag e:
Record route (type 7)
Timestamp (type 68)
