ADTRAN 1200305L1 Defines when RIP advertisements are transmitted, Learned routes do not age

Section 4, User Interface Guide ATLAS 550 System Manual

UPDATES

Write security: 2; Read security: 2

Defines when RIP advertisements are transmitted.

PERIODIC	RIP advertisements are periodically transmitted.
TRIGGERED	RIP advertisements are transmitted only when new routes are learned,
	and learned routes do not age.

AUTHENTICATION

Write security: 2; Read security: 2

Defines the secret used to advertise routes when using RIP V2.

REDISTRIBUTE DEFAULT GATEWAY

Write security: 2; Read security: 2

Enables or disables the transmission of the Default Gateway to be sent with RIP on a per interface basis.

ROUTER > IP > INTERFACES > PROXY ARP

Write security: 2; Read security: 2

Enables or disables Proxy ARP on this interface. Allows the network portion of a group of addresses to be shared among several physical network segments. When ENABLED, and an ARP (address resolution protocol) 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 router answers the request with its own hardware address. When DISABLED (default), the router only responds to ARP request received for its own address.

The ARP protocol itself provides a way for devices to create a mapping between physical (i.e., Ethernet) addresses and logical IP addresses. PROXY ARP uses the 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 then correctly assumes 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.

ROUTER > IP > GLOBAL

Write security: 2; Read security: 2

Provides a way to configure various settings for the Ethernet port. The following menus are available for review and editing:

ROUTER > IP > GLOBAL > DEFAULT GATEWAY

Write security: 2; Read security: 2

Defines or changes the default gateway. Enter the default gateway address by entering a decimal number into the appropriate field and then pressing <Enter> to move to the next field. You will need a default gateway if the LAN contains multiple segments. This address is composed of four decimal numbers, each in the range of 0 to 255, separated by periods. This value is set to 0.0.0.0 by default. Contact your LAN administrator for the appropriate address.
