To turn off the ping response:

1Select Advanced from the main menu. TheAdvanced screen displays (Figure 55).

RIP

The Router supports the Routing Information Protocol (RIP). RIP allows you to set up routing information on one RIP enabled device, and have that routing information replicated to all RIP enabled devices on the network. LAN and WAN interfaces can be configured independently of each other.

Select the RIP tab from theAdvanced > Routing sub-menuto display the screen shown inFigure 58

Figure 58 RIP screen

To set up RIP and auto summary, and to set up or change information for the LAN interface, the WAN interface or both:

1Check the RIP Mode - Enable check box to configure RIP on the Router.

2Check the Auto Summary - Enable check box if you want the Router to send simplified routing data to other RIP devices, instead of full routing data.

3Select one of Disable, Enableor Silentfrom the Operation Modedrop-down list. If you select Enable, the Router transmits RIP update information to other RIP enabled devices. If you select Silent, the Router only receives RIP update messages.

4Select either 1 (for RIPv1) or2 (for RIPv2) from theVersion drop-downlist. 3Com recommends that you use RIPv1 if there is any RIP enabled device on your network that does not support RIPv2. In all other case, select RIPv2.

5Select either Enable orDisable from thePoison Reverse drop-downlist. Enabling Poison Reverse on your Router allows it to indicate to otherRIP-enableddevices that they both have routes that point to each other, preventing data loops.

6Select either Noneor Passwordfrom the Authentication Requireddrop-down list. If you select Password, an unencrypted text password must be set on all RIP-enabled devices.

7If you selected Password at step 6, enter a password at the

Authentication Code prompt.
