In this DHCP Relay with Proxy ARP example:

￿The clients are using dynamic IP address assignment and use the core router as the next hop router (default gateway) in order to create the LAN extension configuration.

￿The DSL interface (dsl1) is unnumbered.

￿The clients, the Ethernet interface (eth1), and the core router interface are all on the same logical network.

￿IP Scoping must be disabled at the DSL card.

￿The DSL router is configured as a DHCP relay.

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 unnumbered

ip route create upstream eth1 155.1.3.1 proxy arp eth1 enable

proxy arp dsl1 enable dhcp relay enable

dhcp relay address 155.1.3.253

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 and proxy arp dsl1 enable commands are not necessary when using FUNI/MPOA link encapsulation.
