Tyrell Corporation’s Network troubleshooting training sessions have assisted the onsite IT team with greater understanding of the enterprise network design. The network had been functioning well since the implementation of the Layer 2 features and the completion of the First Hop Redundancy Protocol – HSRP.

In this challenge, you are tasked with designing and implementing an IP Addressing schemein the Distribution and Core network areas to establish a scalable, fast converging design.

The IP Addressing design will utilise the and 24 IP address space initially.

The Distribution to Core and Core to Data Centre Switch addressing will use the space, while the Data Centre server network will use the space in VLAN 103.

The Data Centre Server network requires enough space to hold a potential 60 client devices on the Network. The network will use the 2ndavailable IP Subnet from the allocated addressing space, as the first subnet has provisionally been allocated for another Server LAN in planning. The Server network devices should have a gateway configured to be the first available IP Address within the range of the newly created scope.

You must ensure that the DCSW1 device has connectivity with all Servers in the new Data Centre networkafter completion of the tasks. The ports facing the Servers should be configured as access VLANS. Distribution to Core and Core to DCSW1 networkswill utilise the /24 IP space:All links between CoreandDistribution switches and the Core and Data Centre switch are to routed links. All potential routed linksare disabled. Layer 3 EtherChannels are to be createdbetween DSW1-DSW2, CSW1-CSW2, CSW1-DCSW1 and CSW2-DCSW1where dual links exist in the topology using standards based protocols. All switches should actively attempt to create the EtherChannels.
