Page 21: Understanding The Technology
Understanding the Technology If this is your first time using a router, then there will be many terms and ideas with which you are not familiar. This chapter explains many of the underlying principles of routing. This chapter contains the following sections: “Routing Concepts (page...
Page 22: Routing Concepts
NauticaRS Release 4.1 Reference Guide Routing Concepts The cost of installing and running a network, and providing sufficient bandwidth to communicate, has generally been proportional to the distance over which the network extends, and the amount of bandwidth required. Large amounts of bandwidth can be provided easily and relatively inexpensively by local area networks (office, department, etc.) by adding more cables and/or equipment, providing network speeds of 10-100 megabits per...
Page 23: What Is A Router
What Is a Router? A router is a device designed to deliver data from the source network to the correct destination network. Once the data has reached the correct network, the router’s task is then to ensure that the data reaches the correct station on that network. Most...
Page 24: Isdn For Resilience
ISDN network and close the connection when no data is being transmitted. When data is transmitted again after a period of inactivity, the Nautica router automatically opens the connection. It does this so quickly that, in most situations, you will not realize that the connection to the remote unit has been closed.
Page 25: Isdn Top-Up Bandwidth On Demand
ISDN Top-Up Bandwidth-On-Demand ISDN means that users can size their networks accurately without worrying about peak demand operation. The Nautica router automatically sets up one or more ISDN circuits to provide extra bandwidth when the leased line or single-channel ISDN line utilization exceeds configurable thresholds.
Page 26: Routing Ip Over Isdn
The router will then automatically learn about those units and create its routing address table. This makes it very easy to set up a Nautica Series router, and it is less prone to user input errors.
Page 27 The Nautica Series also supports a feature called unnumbered links. This means that you do not have to configure an inter-router network for the path. This reduces the number of network addresses needed, because you no longer need to address each link separately, with a consequent reduction in the configuration overhead.
Page 28: Routing Ipx Over Isdn
The Nautica Series has a complete set of Novell spoofing algorithms, so it can emulate the remote network locally and eliminate unnecessary transmissions over the ISDN link. The Nautica router deals intelligently with IPX RIP packets, IPX Watchdog Packets, Serialization packets and SPX packets from each client and server.
Page 29: Connecting To Other Manufacturers' Routers
Connecting to Other Manufacturers’ Routers When connecting LANs together, you may require each end of the WAN link to be attached to a router from a different manufacturer. This is not the best solution because, although the Nautica Series can operate comfortably with other manufacturers’...
Page 30: Ip Addressing
NauticaRS Release 4.1 Reference Guide IP Addressing Because it is used worldwide, TCP/IP networks need a unique addressing structure to ensure that transmitted data reaches its destination. The Internet Protocol uses a 32-bit address structure, divided into two parts. The first part identifies the network, and the second part identifies the host node (station) on that network.
Page 31: Subnet Addressing
Understanding the Technology Class A addresses use an 8-bit network number and a 24-bit node number. Class A addresses are in the range 001.xxx.xxx.xxx to 127.xxx.xxx.xxx (addresses 127.xxx.xxx.xxx are reserved and cannot be assigned to networks or hosts). Class B addresses use a 16-bit network number and a 16-bit node number.
Page 32: Address Resolution
Ethernet networks. Converting an IP address to a matching MAC address is called address resolution. Unless the router can resolve the network IP address to the Ethernet MAC address, it cannot send the data explicitly to the correct device on the LAN. IP uses ARP (Address Resolution Protocol) to do this.
Page 33: Ip Routing Information Protocol
A router using RIP would first look at directly attached networks, and these would be considered to be 1 hop away. Other networks which are further away (i.e., not directly attached) would be n hops away, where n is the number of hops needed to reach the more distant network.
Page 34: Introduction To Ipx
This second method is requested by a node to determine the fastest path to a particular destination, and is responded to by the router attached to the local network. By checking the source address of the response message, the client workstation can determine its own network number.
Page 35: Ipx Service Advertising Protocol
information.
Page 36: Routing Updates
NauticaRS Release 4.1 Reference Guide When a router becomes active on a Novell network, it starts to listen to all SAP broadcasts. The server information is then added to the router’s server information table, so that the router can send SAP broadcasts to each attached Novell network.
Page 37: Open Shortest Path First Protocol (Ospf)
A call that has been made for data transfer will not be kept open by routing updates, because these are not included in the idle calculation for that call. All routing updates received while the connection is closed are copied to the local routing table(s), and the table information is transferred automatically when the next call is made.
Page 38: Dhcp (Dynamic Host Configuration Protocol)
DHCP transaction across subnets and WAN links. This pass-through action is known as BOOTP Relay Agent functionality. As a DHCP server, a Nautica router provides IP addresses manually, automatically or dynamically. It will also manage the leases of dynamically assigned IP addresses and handles client lease releases.
Page 39: Dhcp Protocol Transaction
DHCP Protocol Transaction The DHCP Protocol Transaction takes the following pattern (Figure The client broadcasts a discover message. This discover message contains basic information from the client, for example the MAC address. Multiple servers can respond to this message with an offer message.
Page 40: Figure 1-2. Dhcp Protocol Transaction
NauticaRS Release 4.1 Reference Guide Figure 1-2. DHCP Protocol Transaction To set up the current router as a DHCP server, the DHCP-Enable option in For more information on DHCP and how it should be configured, please refer to Chapter 13.
Page 41: Bootp Relay Agent
By specifying a specific server on the originating router, multiple ISDN calls can be avoided in this case. The option is, by default, turned off in Nautica routers. To enable BOOTP Relay Agent, move to the and set it there.
Page 42: Dial-In User Pptp (Microsoft Fep)
NauticaRS Release 4.1 Reference Guide PPTP creates a tunnel by wrapping PPP packets of information (containing IP, IPX or bridge traffic) within IP packets for transmission through the Internet. Upon receipt of this information, the external IP packets are stripped away and the original packet is then delivered to its destination.
Page 43: Address Translation
To achieve this scenario, a PPP call is made via the ISDN/PSTN to a Nautica 4000 the Internet to the PPTP-enabled host, such as Windows NT, on the remote network, and data is now able to be transmitted. For information on setting up PPTP on a Nautica product, refer to Chapter 5 and Chapter 10.
Page 44: Bridging
If a non-routed protocol is to be forwarded to another network, Nautica series routers can also function as bridges at the same time. Unlike a router, a bridge operating at the Datalink layer forwards all frames (regardless of their network address or protocol) to the remote unit, if the destination address is known to be reachable there.
Page 45: Bandwidth Allocation Control Protocol (Bacp)
If the Forward option is chosen then only those frames in the Filter table are forwarded, all others are rejected. If the Reject option is selected, those frames in the table are rejected and all other options are forwarded. This process applies to the LAN01 path and all paths that have Bridging enabled.
Page 46: The Nautica Implementation Of Bacp
In both these instances the caller is charged for the additional bandwidth. The Nautica Implementation of BACP Before BACP can be used on a Nautica router, there are some parameters that need to be set to support the feature. •...
Page 47 The parameters involved are as follows: Parameter: Function: Parameter: Instructions: Note: the path on which BACP is set must have cnum values. Parameter: Function: 117237-C Rev. A MLink-Enable (Multilink) With this option enabled, when the threshold limits are reached for a path (see page 4-17), MPP will bring up a second link for additional bandwidth.
Page 48 NauticaRS Release 4.1 Reference Guide Parameter: Function: Parameter: Function: Parameter: Function: Note: Dem-Thresh-PC value. Parameter: Function: Instructions: 1-28 Demand Threshold Period (Nautica Wizard) Dem-Period (BCC) This parameter is a time period set in seconds (the default is 10 seconds) and working in conjunction with the Demand Threshold (Dem-Thresh-PC) parameter.
Page 49: Call Request (Example)
Call Request (Example) In this example, the caller governs the request for extra bandwidth. The parameters set on the caller’s and Internet Service Provider’s (ISPs) units are as follows: Caller Setup MLink and BACP enabled Demand Threshold = 80% Demand Period = 30s Idle Threshold 20% Max Bandwidth 128000 CNum 1/...
Page 50 The ISP acknowledges the Call-Request and sends a CNum of 654321. • 1 call 64000 b/s The caller dials the CNum. • 2 calls 128000 b/s The ISP acknowledges the call and provides the files on both links. • 2 calls 128000 b/s The caller completes the download and his Idle Threshold falls below 20% for the Demand Period of 30 seconds.
Page 51: Callback Request (Example)
Callback Request (Example) In this example, the caller and the ISP have different BACP settings, but the ISP still governs the extra bandwidth. Caller Setup MLink and BACP enabled Demand Threshold = 80% Demand Period = 30s Idle Threshold 20% Max Bandwidth 128000 CNum 1/ The caller requests a connection from the ISP.
Page 52 NauticaRS Release 4.1 Reference Guide The download is completed and the ISP utilization of both lines falls below the Idle Threshold of 25% for the Demand Period of 10 seconds. The ISP sends a Link-Drop-Query-Request to the caller. • The caller acknowledges the Link-Drop-Query-Request. •...
Page 53: Network Address Translation (Nat)
The most important benefit of NAT for Nautica routers is the ability for the router to be assigned an IP address by a service provider, without needing to reconfigure the network behind the router.
Page 54: Figure 1-6. Nat With An Internal Network
NauticaRS Release 4.1 Reference Guide In this scenario, the remote router provides the Nautica router with an IP address, but not the PC. The Nautica router translates between the PCs IP address and the IP address supplied by the remote router.
Page 55: Nat Functionality
In this case, each remote router provides the Nautica router with a different IP address. The Nautica router translates between the different addresses depending on the path being used. NAT Functionality NAT functions at the interface between the paths on the router and the router engine.
Page 56: Blacklisting Routes
With a packet from the internal network going out, the source address is translated to the NAT address of the router. The source port address is also translated to a unique value so that replies can be passed back to the correct internal device.
Page 57: Trivial File Transfer Protocol (Tftp)
A path also comes off the blacklist table if a call is received along it from the previously downed router. Also, the blacklist table is cleared if the router is rebooted. For information on setting the blacklist timeout parameter, refer to page 5-10.

Page 113: Working With Paths
Paths contain all the information the router needs to contact a remote unit. It is on the path that ISDN numbers are entered and security is also established. This chapter deals with how to edit existing paths and create new paths.
Page 114: Displaying Path Information
Paths contain information about a destination host or network. When a unit is first configured it will have a default path of eth/lan01 Nautica Wizard were used to set up the router there will be another path called RemotePPP or RemoteNautica. Note: once the unit makes the first call to these paths after setup is complete.
Page 115: Path Statistics
For information on editing existing paths or creating new ones, refer to Chapter 7. For information on WINS, refer to Chapter 16. Path Statistics Statistics can only be displayed for a path that is currently active (receiving or sending a call). To display a list of paths that are active, use the following syntax from any configuration prompt: sh pa st A list of all path statistics will appear:...

Page 322: Isdn Msn
384000, with ISDN MSN this number becomes 384000 to 384009. Now, when an ISDN call is received by the router, it is presented with the CLI and a number representing the MSN. This second number changes depending on the service provider. Some providers will show only the MSN (0 to 9), others will show two digits (00 to 09) and still others will show more digits.
Page 323: Creating An Msn
MSN is used to distinguish between different services attached to the same ISDN line; for example, to differentiate between an ISDN fax and a Nautica 200 on the same ISDN line, or between a normal data call and a PPTP call.

Chapter 16 Using WINS Windows Internet Naming Service (WINS) is a facility for resolving the NetBIOS names used in Microsoft Networking to their associated IP addresses. The Nautica implementation of WINS provides a local static mapping of NetBIOS names to IP addresses. These may be learned either dynamically from the local Ethernet or manually added to the unit.
Page 402: The Wins Configured Object
NauticaRS Release 4.1 Reference Guide The WINS Configured Object Like PAths and DEVices, the WIns context cannot be entered directly. Instead you have to create or modify a WINS object, and this moves you to the WINS configured object prompt. To view any WIns setup on your system, type configuration prompt: box# lso -l...
Page 403 All manually entered names should be described as Dynamic This is the entry type and will only appear as Dynamic if the name has been learned by the router. If the WIns has been entered manually, the entry type should be Static. Info...
