This parameter decides the behavior of the ArpProxy in the IP-DSLAM. It is only valid when forced forwarding is enabled (peaBridgeIpDslam::gatewayFixedForwarding set to true).

The possible values are: 0 proxyAllArpRequests All ARP Requests from the end-user will always be replied with the MAC address of the default gateway configured for the end-user, except gratuitous ARP Requests which will be dropped. This setting should be used when broadcast traffic should be kept to a minimum, for instance when running large L2 networks. 1 proxyNonGwArpRequests All ARP Requests from the end-user to the default gateway are forwarded to the network. Gratuitous ARP Requests are also forwarded to the network. Any request to a non gateway IP will be replied the default gateway MAC address. This setting is needed when running 'Passive ARP Learning' in VRRP enabled routers, or other technologies where ARP from the end-users are needed. 2 proxyNonGratuitousArpRequests All ARP Requests from the end-user will be replied with the MAC address of the default gateway configured for the end-user. Except gratuitous ARP Requests which are forwarded to the network. This setting should be used when broadcast traffic should be kept to a minimum, but the ARP cache timeout in the router is too long to detect end-user MAC replacement. This option is valid from EDA 2.2 SP3.

ARP Requests from the network will always be proxied back.

Terminology: Gratuitous ARP Request: A gratuitous ARP Request is an ARP Request where the Sender IP address and Target IP address is the same. The ARP Requests is broadcasted to other hosts in the same layer 2 network. Hosts use this ARP Request for several reasons: 1) To detect IP address conflicts 2) To advertise the IP and MAC address to other hosts, switch's and routers
