Motorola 6161252-00-01 ユーザーズマニュアル

Select Primary Domain Name Server and enter the IP address for a domain name ser ver. The domain 
name ser ver matches the alphabetic addresses favored by people (for example, robin.hood.com) to the IP 
addresses actually used by IP gateways (for example, 163.7.8.202). 

If a secondar y DNS ser ver is available, select Secondary Domain Name Server and enter its IP address. 
The secondar y DNS ser ver is used by the Router when the primar y DNS ser ver is inaccessible. Entering a 
secondar y DNS is useful but not necessar y.

Select Domain Name and enter your network’s domain name (for example, motorola.com). Motorola 
strongly recommends that you enter a domain name.

Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet 
network that the Router needs to recognize. If this is the case select RIP Options and press Return. This 
will take you to the Ethernet LAN RIP options screen, where you can configure several parameters, 
including RIP v2 MD5 Authentication. See 

.

With Receive RIP set to v1, the Ethernet por t will accept routing information provided by RIP packets 
from other routers that use the same subnet mask. Set to v2, the router will accept routing informa-
tion provided by RIP packets from other routers that use different subnet masks. Set to Both, the 
router will accept information from either RIP v1 or v2 routers.

With Transmit RIP v1 selected, the router will generate RIP packets only to other RIP v1 routers. With 
Transmit RIP v2 (broadcast) selected, the router will generate RIP packets to all other hosts on the net-
work. With Transmit RIP v2 (multicast) selected, the router will generate RIP packets only to other rout-
ers capable of recognizing RIP v2 packets.

If you want to enable Multicast For warding, select Multicast Forwarding and from the pop-up menu, 
choose the type that you want to enable. See 

configuration.

To configure multiple IGMP options, go to the IGMP Setup menu. See 

.

If you want to create Vir tual Redundant Routers, select VRRP Options and press Return. You will be taken 
to the Ethernet LAN VRRP Options screens. See 

.

Select Static Routes to manually configure IP routes. See the section 

 below.

If you select IP Address Serving you will be taken to the IP Address Ser ving screen (see 

). Since no two hosts can use the same IP address at the same time, make sure 

that the addresses distributed by the Router and those that are manually configured are not the same. 
Each method of distribution must have its own exclusive range of addresses to draw from.

If you select Additional LANs you will be taken to the Additional LAN Configuration screen (see 

). Here you can create up to six additional local area networks that can be associated 

with any IP routed inter face.

The IP Subnets screen allows you to configure up to eight Ethernet IP subnets on unlimited-user models, one 
“primar y” subnet and up to seven secondar y subnets, by entering IP address/subnet mask pairs:
