Network Design on cisco packet tracer 6.0

This document proposes a network design using access controls and VoIP. It includes configuration of routers, switches, VLANs, DHCP, RIP routing protocol, frame relay, telnet, ACLs and VoIP protocols like Call Manager Express. The network connects three locations - a head office and two branch offices - using routers, switches, frame relay, VLANs and access controls to filter unauthorized traffic and allow only genuine users. VoIP is implemented using protocols like DHCP, Call Manager Express, phone directory and dial peer configuration to enable voice calls between the locations over the IP network.

NETWORK DESIGN USING ACCESS CONTROLS AND VOIP Saurav Kumar Pandey
CONTENTS  Abstract  Network Topology  Frame – Relay  DHCP  Routing Protocol  VLAN  Telnet  ACL  VoIP
ABSTRACT  To deploy well-designed computer networks supporting converged applications of data, audio, and video.  To support better performance, resilience, security, maintainability.  This is to propose a network model that can be implemented in different network environments and also be used to implement MAN, WAN.  Use of Voice over Internet Protocol technology allows to make a phone call using an Internet connection or a dedicated network that uses the IP protocol, rather than go through the normal telephone line.  This save bandwidth used. Data packets, containing voice information are routed over the network, encoded in digital form.  To filters & check unauthorized traffic that travels across the network.  The major objective of this network design is to allow only the genuine users to access the network and prevent the intruders from accessing it.
NETWORK TOPOLOGY
Network description • This network has a total number of 3 locations locations; 1 Head office,and other two are Branch office-A and Branch Office-B. • The routers used are 2811 • Also have opted for 2960 switches • Have added PC's as voice functionality can be added to those if desired and to check whether both the network could ping each other or not and for various operational functionalities. • Have kept IPV4 addressing sceme to the various networks. • The Head office and the Branch office-A are connected via leased line(Frame Relay).

Frame-Relay  Frame relay is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN). Frame relay puts data in a variable-size unit called a frame and leaves any necessary error correction (retransmission of data) up to the end- points, which speeds up overall data transmission.

RIP(ROUTING INFORMATION PROTOCOL)  It is a dynamic routing protocol technique  RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15.
RIP Config. Router1 Router(config)#router rip Router(config-router)#network 192.168.0.0 Router(config-router)#network 192.168.1.0 Router(config-router)#network 172.20.0.0 Router(config-router)#network 172.21.0.0 contd…

VLAN  In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

TELNET  Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Through Telnet, an administrator or another user can access someone else's computer remotely.
Telnet configuration on router2 & router3 Router2 Router(config)#line vty 0 4 Router(config-line)#password ccna1 Router(config-line)#login Router(config-line)#exit Router(config)#enable password ccie Router3 Router(config)#line vty 0 4 Router(config-line)#password ccna2 Router(config-line)#login Router(config-line)#exit Router(config)#enable password ccie1
Accessing router 2
ACL(Access Control lists)  ACLs are basically a set of commands, grouped together by a number or name that is used to filter traffic entering or leaving an interface. An access control list (ACL) is a table that tells a computer operating system which access rights each user has to a particular system object.
Restricting PC10 from accessing Router2 via telnet Router 3(extended ACL) Router(config)#access-list 101 deny tcp host 172.19.0.2 host 192.168.2.1 eq 23 Router(config)#access-list 101 deny tcp host 172.19.0.2 host 172.17.0.1 eq 23 Router(config)#access-list 101 deny tcp host 172.19.0.2 host 192.168.0.2 eq 23 Router(config)#access-list 101 permit ip any any Router(config)#int f0/0 Router(config-if)#ip access-group 101 in Router(config-if)#exit contd….

Connected phone
Benefits of voip  The call cost is lower, especially over long distances  The infrastructure costs are lower: When it became available any IP network infrastructure is required.  This save bandwidth used. Data packets, containing voice information are routed over the network, encoded in digital form.

    ABSTRACT  To deploywell-designed computer networks supporting converged applications of data, audio, and video.  To support better performance, resilience, security, maintainability.  This is to propose a network model that can be implemented in different network environments and also be used to implement MAN, WAN.  Use of Voice over Internet Protocol technology allows to make a phone call using an Internet connection or a dedicated network that uses the IP protocol, rather than go through the normal telephone line.  This save bandwidth used. Data packets, containing voice information are routed over the network, encoded in digital form.  To filters & check unauthorized traffic that travels across the network.  The major objective of this network design is to allow only the genuine users to access the network and prevent the intruders from accessing it.

    Network description • Thisnetwork has a total number of 3 locations locations; 1 Head office,and other two are Branch office-A and Branch Office-B. • The routers used are 2811 • Also have opted for 2960 switches • Have added PC's as voice functionality can be added to those if desired and to check whether both the network could ping each other or not and for various operational functionalities. • Have kept IPV4 addressing sceme to the various networks. • The Head office and the Branch office-A are connected via leased line(Frame Relay).

    Frame-Relay  Frame relayis a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN). Frame relay puts data in a variable-size unit called a frame and leaves any necessary error correction (retransmission of data) up to the end- points, which speeds up overall data transmission.

    RIP(ROUTING INFORMATION PROTOCOL) It is a dynamic routing protocol technique  RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15.

    VLAN  In computernetworking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

    ACL(Access Control lists) ACLs are basically a set of commands, grouped together by a number or name that is used to filter traffic entering or leaving an interface. An access control list (ACL) is a table that tells a computer operating system which access rights each user has to a particular system object.

    Benefits of voip The call cost is lower, especially over long distances  The infrastructure costs are lower: When it became available any IP network infrastructure is required.  This save bandwidth used. Data packets, containing voice information are routed over the network, encoded in digital form.
