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 service 
domain. 
Refer to

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 message:
„
Record route (type 7)
„
Timestamp (type 68)
