Using The IPv6 Network Assigned Specifically To You

Using The Ipv6 Network Assigned Specifically To You Posted On Blac

Using the IPv6 network assigned specifically to you (posted on Blackboard) design an IPv6 sub-network (using CIDR notation) that will meet the needs of Acme Corporation (from LAB 8). The selected option must follow good network design goals. Develop an IP network number scheme for each type of device on the network. Apply your network IP number scheme by assigning IP addresses to types of devices used at each location. Diagram the entire network applying this scheme.

Here is the IPv6: 2001:ab5:3157:d0::/64. Using GNS3 or Cisco Packet Tracer, complete the setup of each router, switch, and PC in the Toledo-Napoleon-Port Clinton scenario.

a. Each Router must use IPv6 Addressing.

b. Each location must have a switch connected to an Ethernet port. The switch does not need to have an IP address assigned.

c. Each switch must have at least one PC connected using IPv6 addressing.

Apply configuration statements to enable static route entries to allow all devices on the inter-network to communicate.

Apply configuration statements to enable IPv6 RIP dynamic routing protocol to allow all devices on the inter-network to communicate.

Apply configuration statements to enable IPv6 OSPF dynamic routing protocol to allow all devices on the inter-network to communicate.

Create an IPv6 Extended ACL to block ping echo requests from your network. Provide hard copies of all configuration files, route tables, screenshots of successful pings, and blocked pings, along with the network diagram including your IP addressing scheme, to be submitted at the end of the course.

The task of designing an IPv6 network for Acme Corporation based on the assigned IPv6 prefix 2001:ab5:3157:d0::/64 involves a comprehensive approach that aligns with best practices in network architecture. The process encompasses subnetting, address assignment, network device configuration, routing protocol setup, and security implementation through ACLs. This paper discusses each step in detail, emphasizing logical segmentation, efficient routing, and security management in IPv6 networks.

IPv6 Sub-network Design and Addressing Scheme

The primary step involves creating sub-networks tailored for different device categories and locations, adhering to hierarchical addressing principles. The /64 prefix provides ample address space, permitting subdivision into multiple subnets. Considering the three locations—Toledo, Napoleon, and Port Clinton—each site requires its own subnet for routers, switches, and end devices.

For instance, assigning /64 subnets to each location yields three network segments: 2001:ab5:3157:d0:0001::/64 for Toledo, 2001:ab5:3157:d0:0002::/64 for Napoleon, and 2001:ab5:3157:d0:0003::/64 for Port Clinton. Within each subnet, specific address ranges can be designated for routers, switches, and PCs. Router interfaces might occupy addresses such as 2001:ab5:3157:d0:0001::1/64, switches connected to the LAN could be assigned addresses like 2001:ab5:3157:d0:0001::2/64, and PCs can be allocated subsequent addresses incrementally.

Network Device Configuration and IP Address Assignment

Router interfaces at each site are configured with IPv6 addresses from their respective subnets. Switches, being layer 2 devices, do not require IP addresses unless for management purposes; PCs connected to switches receive DHCPv6 or static IPv6 addresses within the subnet. The hierarchical addressing facilitates efficient routing and simplifies network management.

Routing Protocol Implementation

To enable interconnectivity across the sites, routing protocols are vital. Both RIPng and OSPFv3 are suitable for IPv6 routing. Initially, static routes can be configured for specific paths, but for scalability, dynamic routing protocols are preferred.

Configuring RIPng involves enabling RIP on each router and advertising the relevant networks. For example:



R1(config)# ipv6 router rip MYRIP


R1(config-rip)# network 2001:ab5:3157:d0:0001::/64

Similarly, OSPFv3 configuration includes enabling OSPF on each interface and assigning process IDs:



R1(config)# ipv6 router ospf 1


R1(config-rspf)# interface GigabitEthernet0/0


R1(config-if)# ipv6 ospf 1 area 0

These protocols ensure routes are dynamically exchanged and maintained, providing redundancy and efficiency in route computation across the network.

Security Measures with IPv6 ACLs

To prevent unwanted network activity such as ICMP echo requests (pings), Extended IPv6 Access Control Lists (ACLs) are created. For example, deploying a deny rule for ICMPv6 echo-request packets:



ipv6 access-list BLOCKICMP


deny ipv6 any any icmpv6 echo-request


permit ipv6 any any

This ACL can be applied inbound or outbound on router interfaces as needed to restrict ping traffic from the network, enhancing security by mitigating potential reconnaissance efforts.

Conclusion

Designing an IPv6 network for Acme Corporation requires meticulous planning in addressing, subnetting, device configuration, routing, and security. The utilization of hierarchical addressing simplifies network management, while dynamic routing protocols such as RIPng and OSPFv3 provide resilience and scalability. Proper implementation of ACLs ensures network security, making the IPv6 deployment robust and efficient. For practical deployment, configuration commands, route tables, scans of successful and blocked pings, and network diagrams must be documented meticulously.
