RIP

Use this menu to enable RIP on the LAN interface.

MODE	Enables or disables RIP.
PROTOCOL	Specifies the RIP protocol. Choices are V1 (def)
	(which is RIP version 1) or V2 (RIP version 2).
METHOD	Specifies the way the RIP protocol sends out its
	advertisements. Choices are given below.
NONE	All routes in the router table are advertised
	with no modification of the metrics.
SPLIT HORIZON (def)	Only routes not learned from this circuit are
	advertised.
POISON REVERSE	All routes are advertised, but the routes
	learned from this port are “poisoned” with an
	infinite metric.
DIRECTION	Allows the direction at which RIP advertise-
	ments are sent and listened to be specified.

TX AND RX (def)

TX ONLY

RIP advertisements are periodically transmitted and are listened to on this port.

RIP advertisements are periodically transmitted but are not listened to on this port.

RX ONLY	RIP advertisements are not transmitted on
	this port, but are listened.
V2 SECRET	Enter the secret used by RIP version 2 here.

Proxy ARP

This feature allows the network portion of a group of addresses to be shared among several physical network segments. The ARP protocol provides a way for devices to create a mapping between physical addresses and logical IP addresses. Proxy ARP makes use of this mapping feature by instructing a router to answer ARP requests as a "proxy" for the IP addresses behind one of its ports. The device which sent the ARP request will then correctly assume that it can reach the requested IP address by sending packets to the physical address that was returned. This technique effectively hides the fact that a network has been (further) subnetted. If this option is set to YES, when an ARP request is received on the Ethernet port the address is looked up in the IP routing table. If the forwarding port is not on the Ethernet port and the route is not the default route, the 850 will answer the request with its own hard- ware address.
