Chapter 10 - Data-Link Protocols (Encapsulation) Cyclades-PR4000 90 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-PR4000 Chapter 1 1 - Routing Protocols 91 CHAPTER 1 1 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-PR4000 Chapter 1 1 - Routing Protocols 92 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-PR4000 Chapter 1 1 - Routing Protocols 95 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-PR4000 Chapter 1 1 - Routing Protocols 96 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-PR4000 Chapter 1 1 - Routing Protocols 97 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-PR4000 Chapter 1 1 - Routing Protocols 98 OSPF Menu (continued) Ex terna l Me tri c Def ines th e metr ic tha t will be adv ert ised by O SPF.
Cyclades-PR4000 Chapter 1 1 - Routing Protocols 99 OSPF Global Configurations STEP THREE After completing the OSPF interface configuration for all interfaces (even those that will not use OSPF), navigate to the OSPF Menu, CONFIG=>IP=>OSPF . Enter into the OSPF Global Commands menu and set the parameters as indicated in the table below .

The number of such advertisements can p otentially be reduced by condensing different IP networks in to a single range.
Cyclades-PR4000 Chapter 1 1 - Routing Protocols 102 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-PR4000 Chapter 1 1 - Routing Protocols 103 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-PR4000 Chapter 1 1 - Routing Protocols 104 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-PR4000 Chapter 12 - CyROS, the Operating System 114 CHAPTER 12 CYROS, THE OPERA TING SYSTEM This chapter explains various operating system features that are not covered in other chapters: •.
Cyclades-PR4000 Chapter 12 - CyROS, the Operating System 115 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-PR4000 Chapter 12 - CyROS, the Operating System 116 The super user has access to all menus. The usr user is shown a menu, upon sucessful login, with the items chosen in the user ’s profile. The pppauto user is connected directly to the user via PPP .
117 Cyclades-PR4000 Chapter 13 - NA T CHAPTER 13 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.
118 Cyclades-PR4000 Chapter 13 - 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 .

126 Chapter 14 - Filters and Rules Cyclades-PR4000 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 .
127 Cyclades-PR4000 Chapter 14 - Filters and Rules 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 .
128 Chapter 14 - Filters and Rules Cyclades-PR4000 The configuration for “Let e-mail in” is shown in the following figure (obtained by selecting CONFIG =>RULES LIST =>IP =>L in the menus).

132 Chapter 14 - Filters and Rules Cyclades-PR4000 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.
133 Cyclades-PR4000 Chapter 14 - Filters and Rules 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.

136 Chapter 14 - Filters and Rules Cyclades-PR4000 prioritize the access to his web server . He also wants to prioritize e-mail sent by his SMTP server , but the priority should be lower . All other traffic should have the lowest priority . For web server access, the important flow direction is not the user requests, but rather the data requested.
137 Cyclades-PR4000 Chapter 14 - Filters and Rules The configured rules will appear as shown in the following listing. Note that for this type of traffic control, of the traf fic-specific parameters only Flow Priority is used. The Reserved Bandwidth and Bandwidth Priority parameters are not important.
Cyclades-PR4000 Chapter 15 - IPX 138 CHAPTER 15 IPX (INTERNETWORK PACKET EXCHANGE) IPX is an alternative to IP , proprietary to Novell. When IPX is activated, many new menus appear to allow configuration of this type of network.
Cyclades-PR4000 Chapter 15 - IPX 139 Enabling IPX The first step is to activate the IPX feature in the router . This is accomplished using the menu option ADMIN =>ENABLE FEA TURES => IPX. The IPX protocol must also be activated in the menu CONFIG =>IPX => GENERAL.
Cyclades-PR4000 Chapter 15 - IPX 140 The parameter Send SAP Update can be set to Demand, Periodic, or None. This parameter affects both SAP and RIP . Periodic causes the router to send these messages every minute, while choosing Demand will cause the router to send messages only when a message request is received.
Cyclades-PR4000 Chapter 15 - IPX 141 The routing table is displayed by the menu option INFO => SHOW ROUTING T ABLE => IPX. For the example, and using only the static route created above, the routing table appears as in Figure 13.
Cyclades-PR4000 Chapter 16 - Virtual Private Network Configuration 142 CHAPTER 16 VIRTUAL PRIV A TE NETWORK CONFIGURA TION The Virtual Private Network utility can be used on any link using IP routing. It is used to provide greater security between two or more networks connected through a public communications network.
Cyclades-PR4000 Chapter 16 - Virtual Private Network Configuration 143 An example showing a local security network and two remote security networks is shown in Figure 14.
