1. 0:00Hello there. My name is Muhammad Ibrahim
2. 0:02and in this presentation I'll be
3. 0:04discussing stage two of the CSP 450
4. 0:07project. This stage focuses on building
5. 0:10and configuring the network
6. 0:12infrastructure that connects the virtual
7. 0:14machines created earlier in stage one.
8. 0:16The goal is to establish communication
9. 0:19between systems and enable access to
10. 0:22external networks.
11. 0:24During this stage, the virtual
12. 0:26environment for the musical instrument
13. 0:29sales company network was set up. Three
14. 0:32virtual machines were created to
15. 0:35represent the main system in the
16. 0:37environment. A client machine, a server
17. 0:40machine, and a router. The server was
18. 0:43was prepared to host services for the
19. 0:46company while the router was prepared to
20. 0:48manage network communication between
21. 0:50internal internal systems and external
22. 0:53networks. This setup served as the base
23. 0:56environment needed to implement the
24. 0:59network configuration in stage two.
25. 1:03Stage two focuses on configuring the
26. 1:05network that connects all the virtual
27. 1:07machines together. The client server and
28. 1:09router are connected using network
29. 1:12infrastructure that allows them to
30. 1:13communicate. Switches are used to manage
31. 1:16communication within the within the
32. 1:17internal network while the router
33. 1:20provides connectivity to the external
34. 1:22synica network. As a result, devices in
35. 1:24the internal network can communicate
36. 1:26with each other and also reach external
37. 1:29resources such as the internet.
38. 1:33This diagram illustrate the network
39. 1:36layout used in this stage of the
40. 1:38project. Both of the both the clients
41. 1:40and the server connects to the internal
42. 1:42uh network through the Ruba 2500 series
43. 1:46and they operate within VLAN 44 which is
44. 1:49my unique ID number. The Aruba 25 series
45. 1:53connects to the Aruba 6300 through a
46. 1:57trunk link that carries VLAN traffic
47. 1:59between the two switches.
48. 2:02Then the Ruba 6300 connects to the
49. 2:04router through the routed interface.
50. 2:07Finally the router connects to the
51. 2:09internal network.
52. 2:12Finally the router connects the eternal
53. 2:14the eternal network to sica network and
54. 2:16allows eternal internal devices to reach
55. 2:20the internet.
56. 2:22The network infrastructure in this
57. 2:24environment relies on two switches. the
58. 2:27Ruba 6300 as we can see here and the
59. 2:29picture is generated by AI is a little
60. 2:32bit satisfying to see the number of 6300
61. 2:35on the other one 25XX which is the 25
62. 2:38series while we use in this uh project
63. 2:422530 and 2540 so I decided to make to
64. 2:45name it 25XX
65. 2:47so the switches we used uh in this stage
66. 2:51and the rest of the project is going to
67. 2:53be Aruba 6300 and Aruba 25
68. 2:56These switches control how devices are
69. 2:58connected and how traffic flows between
70. 3:01them. They also support VLAN
71. 3:04segmentation and provide services such
72. 3:06as DHCP
73. 3:09automated assignment uh to to automate
74. 3:12the assignment of uh IP addresses. The
75. 3:15next slide as we as we will see
76. 3:18describes how each switch was configured
77. 3:21to support the eternal the eternal
78. 3:24network.
79. 3:25The Ruba the Ruba 6300 switch functions
80. 3:29as the main switch for the Eternal
81. 3:31network. First VLAN 44 is create is
82. 3:34created to represent the Eternal network
83. 3:37used by the client and server systems. A
84. 3:40VLAN interface is then assigned an IP
85. 3:43address so the switch can act as the
86. 3:46gateway for the devices within that
87. 3:48VLAN. This allows devices on the
88. 3:51internal on the internal network to send
89. 3:54traffic through the switch when
90. 3:56communicating with each other. A trunk
91. 3:58interface is configured on the Ruba 6300
92. 4:02switch so VLAN traffic can pass in
93. 4:05between the 6300 switch and the 2500
94. 4:08series switch. This trunk link ensures
95. 4:11that VLAN information is preserved as
96. 4:14traffic moves in between the two
97. 4:16switches.
98. 4:19A routing interface is also create is
99. 4:21also configured to create a direct
100. 4:23connection between the switch and the
101. 4:24router using a small slash30
102. 4:27network. This allows a switch and router
103. 4:30to exchange network traffic between the
104. 4:33internal uh network and other networks.
105. 4:37OBF is enabled so that the Ruba 6300
106. 4:42switch can exchange routing information
107. 4:44with the router. This allows the devices
108. 4:48to dynamically share routes instead of
109. 4:51relying only on a static a static
110. 4:54routing or a static routes.
111. 4:59The switch also runs a DHCP service that
112. 5:02assigns IP addresses to devices on VLAN
113. 5:0644.
114. 5:07When a device join the network, it
115. 5:09automatically receives an IB addresses
116. 5:11or an IP address gateway information and
117. 5:15DNS configuration. A DHCP reservation is
118. 5:19configured for the server so that it's
119. 5:22it always receives the same IP address
120. 5:25from the DHCP server. This is important
121. 5:28because the servers that the servers the
122. 5:31server the servers need consistent
123. 5:35addressing so that other devices can
124. 5:39reliably locate them on the network. In
125. 5:42addition, a default route is configured
126. 5:44on the switch so that traffic destined
127. 5:47for external networks can be forwarded
128. 5:50to the router.
129. 5:52The Aruba 25 series switch operates as
130. 5:55the access switch for the network. BLM
131. 5:5944 is also is also created on this
132. 6:02switch so it can be so it can support
133. 6:05the same internal network. A management
134. 6:07IB address is assigned to the VLAN so
135. 6:10administr administrators can remotely
136. 6:13access and manage the switch. A trunk
137. 6:16port is configured so VLAN VLAN traffic
138. 6:19can travel between the Aruba 25 and the
139. 6:2263 switch smoothly.
140. 6:27An access port is configured on the
141. 6:29Aruba 2500 series to allow devices to
142. 6:32connect directly to the internal
143. 6:34network. Devices connected to this port
144. 6:37automatically become member of VLAN 44
145. 6:40and can and can communicate with other
146. 6:42systems within the same network.
147. 6:47The client represents a typical user
148. 6:50workstation within the network
149. 6:52environment. It connects to the internal
150. 6:55network through the Ruba 25 series
151. 6:57switch. When the client connects to the
152. 7:00network, it can automatically receives
153. 7:02an IP address from the DHCP service
154. 7:04running on the on the switch. The
155. 7:08configurations allows the client to
156. 7:10communicate with other devices on the
157. 7:12network and access external resources
158. 7:15through the router.
159. 7:19The Ubuntu server also connects to the
160. 7:21internal to the internal network through
161. 7:23the Ruba 25 series switch. Like the
162. 7:26client, the server receives its network
163. 7:29configuration from the DHCP service
164. 7:32running on the switch. However, a DHCP
165. 7:35reservation is used to ensure that the
166. 7:38server always receives the same IP
167. 7:41address whenever it connects to the
168. 7:43network.
169. 7:46Now we move on to the router and is
170. 7:48responsibility for connecting the
171. 7:50internal network to the external synica
172. 7:53network. It uses two network interfaces
173. 7:56to to separate internal traffic from
174. 7:59external one. The eternal the internal
175. 8:03interface connects to the Aruba 6300
176. 8:06uh using the a static IP address. The
177. 8:09external interface connect to the Synica
178. 8:12network and receives its IP address
179. 8:14automatically through DHCP.
180. 8:17This setup allows the router to forward
181. 8:21traffic between the internal network and
182. 8:23the external one.
183. 8:26Several devices are configured on the
184. 8:28router to allow to allow it to properly
185. 8:32to properly manage network traffic. IB4
186. 8:36forward is enabled so the router can
187. 8:39pass packets between the internal and
188. 8:42external.
189. 8:44FRR is used to manage routing and
190. 8:47exchange routing information with the
191. 8:50Aruba 6300 switch and the OBF protocol.
192. 8:54NFT table as well is used to manage
193. 8:56firewall rules and perform network
194. 8:59address translation.
195. 9:02Network address translation allows
196. 9:04devices on the internal network to
197. 9:06access external network using the
198. 9:08router's connection.
199. 9:11Last but not least, when the when the
200. 9:13when the client or the server needs to
201. 9:16communicate with the external network,
202. 9:18the traffic is first sent to the default
203. 9:21gateway on the Aruba 6300 switch. The
204. 9:24switch then forward the traffic to the
205. 9:26router through the routed interface. The
206. 9:29rout the the router sends the traffic to
207. 9:31the synica network through the external
208. 9:34interface. Network address translation
209. 9:36allows exter allows internal devices to
210. 9:39use the router connection with the
211. 9:41communication with the exter with with
212. 9:44communication
213. 9:45with external network. And this answer
214. 9:48the question how internal devices access
215. 9:52the internet and the diagram shows the
216. 9:55process that it goes through.
217. 9:59At the end of this stage the network
218. 10:01infrastructure of a musical instrument
219. 10:03cells company environment has been su
220. 10:05successfully configured. The switches
221. 10:07provide connectivity within the intern
222. 10:10within within the internal network while
223. 10:12router enables communication between
224. 10:14internal and external synica network.
225. 10:18Thank you for watching.
