Configuring the DSL Router
3-4
6371-A2-GB20-00 March 2000
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 each of the configured
Service Domains.
Refer to Chapter 4, DSL Router Configuration Examples , for further details.
Network Considerations
The DSL routers can be configured to function in a variety of network
environments. The following sections provide descriptions of some of the DSL
router features:
H
Address Resolution Protocol (ARP)
H
Proxy ARP
H
Network Address Translation (NAT)
— Basic NAT
— Network Address Port Translation (NAPT)
— Applications Supported by NAT
H
Dynamic Host Configuration Protocol (DHCP) Server
H
DHCP Relay Agent
H
IP Filtering
Address Resolution Protocol (ARP)
Address Resolution Protocol, as specified in RFC 826, is supported in the DSL
router. The DSL router provides for a total of 256 ARP table entries. The timeout
for completed and for uncompleted ARP table entries is configurable.
The Command Line Interface provides the ability to:
H
Create up to 64 static ARP table entries to be retained across power cycles.
H
Display the ARP table.
H
Delete ARP table entries.
H
Add and delete dynamic ARP table entries by the DHCP server function.

Dynamic Host Configuration Protocol (DHCP) Server on page 3-7.
