It is characterized as an "interior" gateway protocol, and is typically used in small to medium-sized networks. 5-14 v1. 0, March 2006 IP Routing Services NETGEAR 7000 Series Managed Switch Administration Guide RIP Configuration A router running RIP will send the contents of its routing table to each of its adjacent routers every 30 seconds. When a route is removed from the routing table it will be flagged as unusable by the receiving routers after 180 seconds, and removed from their tables after an additional 120 seconds. There are two versions of RIP: · RIPv1 defined in RFC 1058 ­ Routes are specified by IP destination network and hop count ­ The routing table is broadcast to all stations on the attached network RIPv2 defined in RFC 1723 ­ Route specification is extended to include subnet mask and gateway ­ The routing table is sent to a multicast address, reducing network traffic ­ An authentication method is used for security · The 7000 Series Managed Switch supports both versions of RIP. You may configure a given port: · · · · To receive packets in either or both formats To transmit packets formatted for RIPv1 or RIPv2 or to send RIPv2 packets to the RIPv1 broadcast address To prevent any RIP packets from being received To prevent any RIP packets from being transmitted IP Routing Services v1. 0, March 2006 5-15 NETGEAR 7000 Series Managed Switch Administration Guide CLI Example The configuration commands used in the following example enable RIP on ports 1/2/2 and 1/2/3 as shown in the network illustrated in Figure 5-4 Figure 5-4 Example #1: Enable Routing for the Switch: The following sequence enables routing for the switch: (Netgear Switch) #config (Netgear Switch) (Config)#ip routing (Netgear Switch) (Config)#exit 5-16 v1. 0, March 2006 IP Routing Services NETGEAR 7000 Series Managed Switch Administration Guide Example #2: Enable Routing for Ports The following command sequence enables routing and assigns IP addresses for ports 1/2/2 and 1/ 2/3.

Enable RIP for ports 1/2/2 and 1/2/3 This command sequence enables RIP for ports 1/2/2 and 1/2/3. Authentication defaults to none, and no default route entry is created. The commands specify that both ports receive both RIPv1 and RIPv2 frames, but send only RIPv2 formatted frames.

OSPF offers several benefits to the administrator of a large and/or complex network: · Less network traffic: ­ ­ ­ · Routing table updates are sent only when a change has occurred Only the part of the table which has changed is sent Updates are sent to a multicast, not a broadcast, address Hierarchical management, allowing the network to be subdivided The top level of the hierarchy of an OSPF network is known as an autonomous system (AS) or routing domain, and is a collection of networks with a common administration and routing strategy. The AS is divided into areas: intra-area routing is used when a source and destination address are in the same area, and inter-area routing across an OSPF backbone is used when they are not. An inter-area router communicates with border routers in each of the areas to which it provides connectivity. The 7000 Series Managed Switch operating as a router and running OSPF will determine the best route using the assigned cost and the type of the OSPF route. The order for choosing a route if more than one type of route exists is as follows: 5-18 v1. 0, March 2006 IP Routing Services NETGEAR 7000 Series Managed Switch Administration Guide · · · · Intra-area Inter-area External type 1: the route is external to the AS External Type 2: the route was learned from other protocols such as RIP CLI Examples The examples in this section show you how to configure a 7000 Series Managed Switch first as an inter-area router and then as a border router. They show two areas, each with its own border router connected to one inter-area router. The first diagram shows a network segment with an inter-area router connecting areas 0. 0. 0. 2 and 0. 0. 0. 3. The example script shows the commands used to configure a 7000 Series Managed Switch as the inter-area router in the diagram by enabling OSPF on port 1/2/2 in area 0. 0. 0. 2 and port 1/2/ 3 in area 0. 0. 0. 3. IP Routing Services v1. 0, March 2006 5-19 NETGEAR 7000 Series Managed Switch Administration Guide Example #1 Configuring an Inter-Area Router Figure 5-5 Enable Routing for the Switch. The following command sequence enables ip routing for the switch. (Netgear Switch) #config (Netgear Switch) (Config)#ip routing (Netgear Switch) (Config)#exit Assign IP Addresses for Ports. The following sequence enables routing and assigns IP addresses for ports 1/2/2 and 1/2/3: (Netgear (Netgear (Netgear (Netgear (Netgear (Netgear (Netgear (Netgear (Netgear (Netgear Switch) Switch) Switch) Switch) Switch) Switch) Switch) Switch) Switch) Switch) #config (Config)#interface 1/2/2 (Interface 1/2/2)#routing (Interface 1/2/2)#ip address 192. 150. 2. 1 255. 255. 255. 0 (Interface 1/2/2)#exit (Config)#interface 1/2/3 (Interface 1/2/3)#routing (Interface 1/2/3)#ip address 192. 150. 3. 1 255. 255. 255. 0 (Interface 1/2/3)#exit (Config)#exit 5-20 v1. 0, March 2006 IP Routing Services NETGEAR 7000 Series Managed Switch Administration Guide Specify Router ID and Enable OSPF for the Switch.
