Motorola 6161252-00-01, Enterprise Series Routers

IP Setup 7-3

•Select Primary Domain Name Server and enter the IP address for a domain name server. The domain

name server 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 secondary DNS server is available, select Secondary Domain Name Server and enter its IP address.

The secondary DNS server is used by the Router when the primar y DNS server is inaccessible. Entering a

secondary DNS is useful but not necessary.

•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 “RIP Options” on page 7-9.

•With Receive RIP set to v1, the Ethernet port 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 Forwarding, select Multicast Forwarding and from the pop-up menu,

choose the type that you want to enable. See “Multicast Forwarding” on page 7-32 for detailed

conﬁguration.

To conﬁgure multiple IGMP options, go to the IGMP Setup menu. See “IGMP (Internet Group Management

Protocol)” on page 3-52.

•If you want to create Virtual Redundant Routers, select VRRP Options and press Return. You will be taken

to the Ethernet LAN VRRP Options screens. See “Virtual Router Redundancy (VRRP)” on page 7-34.

•Select Static Routes to manually conﬁgure IP routes. See the section “Static routes” on page 7-6 below.

•If you select IP Address Serving you will be taken to the IP Address Serving screen (see “IP Address

Serving” on page 7-17). 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 “Additional

LANs” on page 7-38). Here you can create up to six additional local area networks that can be associated

with any IP routed interface.

IP subnets

The IP Subnets screen allows you to conﬁgure up to eight Ethernet IP subnets on unlimited-user models, one

“primary” subnet and up to seven secondary subnets, by entering IP address/subnet mask pairs:
