Tt describes various networking tasks and configurations that should be applied to the provided network topology, using Cisco Packet Tracer or a similar network simulation tool. Here are the commands and configurations outlined in the document for each task:
-Create the network design as shown in the pic (please use same devices and links)
Basic Device Configurations:
For switches and routers:
Set the device name.
Describe each interface.
Assign IPv4 addresses to each interface.
Enable all interfaces.
Test direct links with the ping command.
VLAN Configurations:
Create VLANs (VLAN10 for IT and VLAN20 for HR on one side, VLAN30 for IT and VLAN40 for HR on the other).
Configure access and trunk ports with the appropriate recommendations.
Set up inter-VLAN routing and adhere to the IP addressing scheme shown in the network.
Configure DHCP for each VLAN, paying attention to the Default Gateway.
Test end devices for IP acquisition and connectivity.
Spanning-Tree Protocol (STP) Configurations:
Change the STP version to Rapid-PVST on all devices.
Designate DSW1 as the root for VLAN10, DSW2 for VLAN20, DSW3 for VLAN30, and DSW4 for VLAN40.
Configure backup root roles in case of failure.
Enable PortFast and BPDU Guard on appropriate ports.
Adjust the STP path cost as necessary, with explanations.
Hot Standby Router Protocol (HSRP) Configurations:
Set DSW1 as active for VLAN10 and standby for VLAN20, DSW2 as active for VLAN20 and standby for VLAN10, and so on for DSW3 and DSW4.
Ensure HSRP priorities match the STP selections.
Ensure the original active device takes back the active role when it comes back online.
Speed up the fault detection and transition from standby to active to less than 1 second.
Open Shortest Path First (OSPF) Configurations:
The links between R devices should belong to Area 0.
Assign network 172.16.V.0 to Area 12 and network 172.17.V.0 to Area 34.
Prioritize R devices to become Designated Routers (DR) and prevent DSW devices from becoming Backup Designated Routers (BDR).
Ensure no routing information can be received from other devices.
Adjust the OSPF cost to change the route selection, with explanations.
Test connectivity between end devices on both sides.
Time Synchronization and Logging:
Ensure time synchronization across all devices using NTP.
Save important logs on a specific device through Syslog.
Configure SNMP for monitoring and management purposes.
Access Control Lists (ACLs):
Prevent VLANs dedicated to HR on both sides from communicating with each other.
Restrict IT VLANs from managing devices on the opposite side while allowing other protocols like SSH and Telnet.
Quality of Service (QoS):
Create a high-priority class for VoIP with Priority Queuing (PQ).
Establish Class-Based Weighted Fair Queuing (CBWFQ) for different data types with importance categorized into classes.
Use appropriate DSCP markings.
Manage congestion and queues with mechanisms like Class-Based Weighted Random Early Detection (CBWRED).
