5446 RTU Setup
C-7
8000-A2-GB20-50
April 2000
Configuration Requirements
Host routes use the IP address assigned to the end-user systems supported by
the 5446 RTU. Service domain IDs use the IP address information pertaining to
the 5446 RTU within the service domain.
Refer to IP Injection Tool Group Objects Table on page C-11 for IP Injection
group object details. The first three Route Type entries must be entered in the
5446 RTU IP configuration table:
H NAP address. This address is automatically injected across the DSL link by
the corresponding DSL port of the 8546 card and should not be modified.
H Service Provider address. This is the IP address assigned to the 5446
RTU’s Ethernet port in the service provider domain.
H Host address. The Host address is the IP address of the single end-user
system or subnetwork connected to the 5446 RTU and is configured via the
IP Injection tool.
H Default Gateway address. The default gateway is used:
— When Network Address Translation (NAT) must occur, or
— To forward any downstream traffic that does not meet any existing
forwarding policies.
If a default gateway is not configured, unknown traffic is dropped.
Only one default gateway is used and is not included in the maximum of 32
locally attached hosts. The ipInjectionNHRAddr (ipInjectionEntry 5) object is
used to enter the IP Address of the default gateway and requires a next hop
router address.
H Next Hop Router address. The ipInjectionNHRAddr (ipInjectionEntry 5)
object applies when the value of ipInjectionType is set to Host. This object
can contain the IP address of a:
— Next Hop Router for a defined host or subnet, or
— Default Gateway used to send unknown traffic downstream.
NOTE:
Up to 32 host entries for end-user systems can be specified. Of the
32 entries, each can be statically provisioned with a Next Hop Router.
The 5446 RTU continues to support a mix of dynamic and statically
assigned addresses.
