Cyclades-PR2000 39 Chapter 4 - Step-by-Step Instructions STEP FOUR Now , a static backup route must be created for the secondary link. It is assumed that a route of some sort (static, RIP , etc.) already exists for the primary link. The static route parameters for the example secondary link are shown in Figure 4.
Cyclades-PR2000 40 Chapter 4 - Step-by-Step Instructions STEP SIX The multilink circuit can be tested by temporarily deactivating the interface on the primary link. This is done in the ADMIN=> ST ART/STOP INTERF ACE menu by selecting the SW AN interface.
Chapter 5 - Configuration of the Ethernet Interface 41 Cyclades-PR2000 CHAPTER 5 CONFIGURA TION OF THE ETHERNET INTERFACE The PR2000 has one Ethernet 10Base-T interface, provided in a standard RJ-45 modular jack, which should be connected to an Ethernet hub or switch.

Chapter 6 - The SW AN and Async Interfaces 45 Cyclades-PR2000 CHAPTER 6 THE SW AN AND ASYNC INTERF ACES This chapter describes how to configure a SW AN interface. The physical link should be set up as shown in chapter 2, according to the type of modem or device at the other end of the connection and the type of SW AN port.
Chapter 6 - The SW AN and Async Interfaces 46 Cyclades-PR2000 STEP TWO The second step is to choose a data-link protocol in the Encapsulation Menu. There are many encapsulation options on this interface.
Chapter 6 - The SW AN and Async Interfaces 47 Cyclades-PR2000 STEP FOUR If PPP Encapsulation is being used, a type of authentication should be chosen. This is done in the authentication menu.
Cyclades-PR2000 Chapter 7 Network Protocols 48 CHAPTER 7 NETWORK PROTOCOLS The second step in most interface configurations is to choose which network protocol to use and assign values to the relevant parameters. At least one of IP , T ransparent Bridge, or IPX (optional, and discussed in chapter 13) must be activated.
Chapter 7 Network Protocols 49 Cyclades-PR2000 The IP Protocol If the preset values provided by the operating system are accepted, the interface will work at a basic level.
Cyclades-PR2000 Chapter 7 Network Protocols 50 Network Protocol (IP) Menu (Continued) Parameter Des cription IP MTU Assigns the si ze of the Maximum Tra nsmission Unit for t he interface. T his determines whether or not a given IP datagram is fragmented .
Chapter 7 Network Protocols 51 Cyclades-PR2000 The T ransparent Bridge Protocol The T ransparent Bridge Protocol can be used in conjunction with either IP or IPX.
Cyclades-PR2000 Chapter 8 - Data-Link Protocols (Encapsulation) 52 CHAPTER 8 DA T A-LINK PROTOCOLS (ENCAPSULA TION) Each encapsulation option is presented in a separate section in this chapter . Not all data-link protocols are available for all interfaces.

Cyclades-PR2000 Chapter 8 - Data-Link Protocols (Encapsulation) 54 CHAR The configuration of the CHAR data-link protocol is confined to one menu, CONFIG =>INTERF ACE =><LINK> =>ENCAPSULA TION =>CHAR. Informa tion about all the parameters appearing in this menu is provided in the table below .
Cyclades-PR2000 55 Chapter 8 - Data-Link Protocols (Encapsulation) PPPCHAR The configuration of the PPPCHAR protocol is contained in the menu CONFIG =>INTERF ACE =><LINK> =>ENCAPSULA TION =>PPPCHAR. The parameters for PPPCHAR are a combination of those for PPP and CHAR.
Cyclades-PR2000 Chapter 8 - Data-Link Protocols (Encapsulation) 56 The Local Management Interface (LMI) Protocol provides services not available in simple Frame Relay . It is used for controlling the connection between the user and the network. It monitors this link, maintains the list of DLCs, and sends status messages about the PVCs.
Cyclades-PR2000 57 Chapter 8 - Data-Link Protocols (Encapsulation) STEP TWO After configuring the general parameters, each DLC must be defined. An example will be used to demonstrate the procedure. A public Frame Relay network connecting offices in São Paulo, Rio de Janeiro, Salvador , and Recife is shown in Figure 1 1.

Cyclades-PR2000 63 Chapter 8 - Data-Link Protocols (Encapsulation) STEP TWO The next step is to create a static routing table associating each remote X.121 address with an IP address or a TCP Socket location. This is done in the Add DTE menu, which appears at the end of the X.
Cyclades-PR2000 Chapter 9 - Routing Protocols 64 CHAPTER 9 ROUTING PROTOCOLS Routing Strategies Routing can be done either statically or dynamically . Static Routing Static routing is recommended when the network contains a small number of routers and other equipment.
Cyclades-PR2000 Chapter 9 - Routing Protocols 65 Static Routes Routers used in very small or simple networks may use static routes as the primary routing method. When RIP or OSPF are used, some static routes may still be needed. Configuration of static routes will be explained using two examples.

Cyclades-PR2000 Chapter 9 - Routing Protocols 68 RIP Configuration CyROS supports three basic types of RIP: 1 RIP1 [RFC 1058] 2 RIP2 with broadcast (compatible with RIP1) [RFC 1723] 3 RIP2 with multicast [RFC 1723] The primary difference between RIP1 and RIP2 is that only RIP2 advertises subnet masks and next hops.
Cyclades-PR2000 Chapter 9 - Routing Protocols 69 OSPF The OSPF (Open Shortest Path First) routing protocol is significantly more complicated than RIP . The determination of which protocol is better suited to a given network is beyond the scope of this manual.
Cyclades-PR2000 Chapter 9 - Routing Protocols 70 First, some definitions: • An Autonomous System (AS) is a portion of the network that will use a single routing strategy . It is made up of a backbone area and optionally of non-backbone areas. • OSPF Areas are sub-systems that have identical routing databases.

Cyclades-PR2000 Chapter 9 - Routing Protocols 75 STEP SIX It is not always possible to connect all areas directly to the backbone. When an area is connected to the backbone only through another area, two virtual links must be created. One from the backbone to the unattached area and one from the unattached area to the backbone.
Cyclades-PR2000 Chapter 9 - Routing Protocols 76 BGP-4 Configuration The BGP-4 routing protocol is used for routing on the Internet, performed between Autonomous Systems (ASs). An autonomous system is defined as: · A set of routers and networks under the same administration.
Cyclades-PR2000 Chapter 9 - Routing Protocols 77 The last option is to aggregate the addresses contained in the local autonomous system in order to present an aggregated route to the outside world. This is done in the last step. 8. Aggregate the addresses contained in the AS.
Cyclades-PR2000 Chapter 9 - Routing Protocols 78 CONFIG=>IP=>BGP4=>GLOBAL Parameter Des cription BGP4 Protocol Activates the protocol. Local AS Number This number is assigned by the service provider.
Cyclades-PR2000 Chapter 9 - Routing Protocols 79 STEP TWO The neighbor menu identifies the routers inside and outside the AS that will communicate with the router via BGP- 4.

Cyclades-PR2000 Chapter 10 - CyROS, the Operating System 87 CHAPTER 10 CYROS, THE OPERA TING SYSTEM This chapter explains various operating system features that are not covered in other chapters: • .
Cyclades-PR2000 Chapter 10 - CyROS, the Operating System 88 Other users can be created and the user “usr” can be assigned a password. The password of the super user should be changed as soon as possible. The menu CONFIG=>SECURITY=>USERS allows addition, deletion, and modification of the list of users.
Cyclades-PR2000 Chapter 10 - CyROS, the Operating System 89 login name is indicated when the auto user is configured, the user is logged in to the remote host directly (though a password may be necessary , depending on the remote host configuration).
90 Cyclades-PR2000 Chapter 1 1 - NA T CHAPTER 1 1 NA T (NETWORK ADDRESS TRANSLA TION) NA T exists to convert local IP addresses into Internet “global” IP addresses. Internet IP addresses are assigned by Internet providers. Due to the explosion of the internet, these numbers are scarce.
91 Cyclades-PR2000 Chapter 1 1 - NA T There are two types of NA T available in CyROS -- Normal NA T and Expanded NA T . This chapter describes Expanded NA T .

99 Cyclades-PR2000 Chapter 12 - Filters and Rules Exterior Router The exterior router is the network’s first defense against attacks. For this reason, it is reasonable to prohibit all packets except for those explicitly allowed. This is done by choosing the Default Scope to be Deny .
100 Chapter 12 - Filters and Rules Cyclades-PR2000 Steps necessary to activate filtering on the exterior router in the example: 1 There are two interfaces with two directions each. Filtering on link 1 requires the creation of two rule lists, called exterior_in and exterior_out .
101 Cyclades-PR2000 Chapter 12 - Filters and Rules The configuration for “Let e-mail in” is shown in the following figure (obtained by selecting CONFIG =>RULES LIST =>IP =>L in the menus).

103 Cyclades-PR2000 Chapter 12 - Filters and Rules Interior Router If an interior router exists in the network, the administrator may decide to use a Default Scope of Permit . In this case, all undesired traffic must be excluded by a rule in the rule list.
104 Chapter 12 - Filters and Rules Cyclades-PR2000 The configuration for “Stop forged packets” is shown in the following listing: Rules L ists Rule List Nam e Rule Defau lt List Linked Status Scop.
105 Cyclades-PR2000 Chapter 12 - Filters and Rules T raffic Rule Lists There are three kinds of traffic rules that can be configured in CyROS. The first two determine a division of bandwidth for traff.
106 Chapter 12 - Filters and Rules Cyclades-PR2000 The third determines which services have priority flowing through the router: 3 Service Prioritization. An Internet provider has three clients connected to the same router . Client A is larger and without traffic control would overwhelm the router to the exclusion of Clients B and C.
