In this DHCP Relay with Proxy ARP example:
H
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.
H The DSL line is configured (at the DSLAM/GranDSLAM chassis) for VNET
mode.
H
The DSL interface (dsl1) is unnumbered.
H The clients, the Ethernet interface (eth1), and the core router interface are all
on the same logical network.
H
IP Scoping must be disabled at the DSL card.
H
The DSL router is configured as a DHCP relay.
The command line syntax for this example is:
ifn address eth1 155.1.3.254 255.255.255.0
ifn address dsl1 unnumbered
ip route create upstream eth1 155.1.3.253
proxy arp eth1 enable
proxy arp dsl1 enable
dhcp relay enable
dhcp relay address 155.1.3.252
