4. DSL Router Configuration Examples
6300-A2-GB20-10 November 2003
4-5
The commands and syntax for this example are:
ip routing enable
ifn address eth1:1 10.1.3.1 255.255.255.0
ifn address dsl1 155.1.3.2 255.255.255.0
ip route create upstream eth1 155.1.3.1
nat basic address 155.1.3.0
nat basic map 155.1.3.3 10.1.3.2 10.1.3.5
nat basic enable
proxy arp dsl1 enable
NOTES:
— The IP address assigned for the DSL interface and the IP address in NAT
static mappings can be in the same subnet, but cannot be the same IP
address.
— When IP Scoping is enabled, Basic NAT is enabled and the dsl1 interface
is NOT part of the Basic NAT global IP network, only the dsl1 interface’s IP
address must be entered into the client VNID table.
— The ip routing enable command is only required when using
firmware version 4.2.5 or higher.
— FUNI/MPOA (1483 routed) link encapsulation can be used with this
configuration and the DSL card Models 8304, 8314, 8344, and 8374. Link
encapsulation is configured on the DSL port. This link encapsulation must
match the core network encapsulation type. The ip route create
upstream and proxy arp dsl1 enable commands are not
necessary when using FUNI/MPOA link encapsulation.
