Can I please get help with this question?
You are working on a free form Packet Tracer challenge activity – as seen in Figure 1, you have been given the ‘London Railways’ network.' The purpose of this EMA question is to build upon each of the following tasks that are designed to test your practical knowledge of OSPF'?

Your task comes in five stages, where you must build a complex OSPF network with additional features. You have been issued the following network 66.0.0.0/8 Task 1 Designing the Network You can divide the network in any way you desire, you must write a short 100-word max justification regarding the design of your addressing scheme to solve the challenge. [Note: 100 words, excludes any relevant tables or diagrams] Task 2 Building OSPF Based on the diagram and your proposed addressing scheme – configure OSPF, on all routers and interfaces (please read exception note below). All the PC’s and the single Server must also be configured to be members of each OSPF network. Provide evidence by showing the configuration of Paddington and St Pancras as well as the ‘show ip route’ outputs from Victoria and Euston. Please DO NOT include screen shots, this must be the text-based outputs Exception Note: GRE Marylebone and GRE Liverpool St MUST NOT be included in this OSPF Network. Task 3 GRE Create a GRE tunnel to run from Marylebone to Liverpool St. Ensure that it connects two ends of a private network use 192.168.0.0/24 for Marylebone and 192.168.1.0/24 for Liverpool St Configure a static route between both ends of the tunnel and change the ‘GRE’ hosts (PC’s) to test connectivity. Share text output from both Marylebone and Liverpool St. Please show a single screen shot of GRE Liverpool St successfully pinging GRE Marylebone Task 4 ACL’s Create an extended ACL on Victoria it must block only HTTP traffic from OSPF 100, 200, 300 and allow HTTP traffic from all other networks. All other traffic types must not be blocked. Show the text-based output from Victoria – also explicit command line proof on Victoria. As well as screenshots from the OSPF 100 and 101 PC’s, demonstrating that the ACL is blocking and allowing the correct traffic.

HIGH LEVEL NETWORK DIAGRAM 
			        Physical & Logical
Task 1 Designing the Network
In this assignment, all devices area connected with OSPF
Routing OSPF Protocol and area 0(Backbone area), In perimeter all routers area connected via OSPF and Layer 2 VLAN 99.
Main Perimeter routers are configured with /26 subnet to build a connection with other area routers
IP 66.0.0.0
Subnet 255.255.255.192
All PC are connected with OSPF routers are configured with /25 subnet
IP 66.1.0.0 – 66.9.0.0 / 25
GRE tunnel is built between the GRE Livepool St to GRE Maylebone. As per the request only GRE tunnel has built for routing, there is no security protocol is configuring to protect the tunnel.
