In this basic routing example:
There are multiple clients with statically assigned public IP addresses configured on the Ethernet side of the DSL router.
The IP addresses of the clients are contained within the subnet specified by the configured Ethernet IP address and subnet mask.
The next hop router (default gateway) of the clients is the Ethernet interface (eth1) of the DSL router.
The next hop router for downstream forwarding from the core router is the DSL interface (dsl1) of the DSL router.
The commands and syntax for this example are:
ip routing enable
ifn address eth1 155.1.3.254 255.255.255.0 ifn address dsl1 155.1.4.254 255.255.255.0 ip route create upstream eth1 155.1.4.1
NOTES:
—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 command is not necessary when using FUNI/MPOA link encapsulation.
—If IP Scoping is enabled, the clients’ IP addresses must be entered into the client VNID table.
