DHCP Relay with Proxy ARP Configuration Example
In this DHCP Relay with Proxy ARP example:
T 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.
T The DSL interface (dsl1) is unnumbered.
T The clients, the Ethernet interface (eth1), and the core router interface are all
on the same logical network.
T IP Scoping must be disabled at the DSL card.
T 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:
— Bridging mode is recommended although this configuration is possible
when using firmware version 4.2.5 or higher.
— 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.
