2.1. Address Planning
The given block of IP address is divided into different subnet for the development of
the IP addressing plan and configure the interface of the router according to the IP addressing
plan. The router is configured following the EIGRP routing protocol and a prototype of the
network is configured in cisco packet tracer 7.2 for the identification of the errors in the
network. The network is tested with running the ping command such that it can be tested to
reach different address in the network.

IPv4IPv6 Network NAT-PT
Th HQ router is configured with NAT -PT such that it can connect with the Ipv4 and
Ipv6 networks. With the help of the network address translation the Ipv6 device can
communicate with the device that are configured with IPv4 address. It can create a direct
communication with the different types of network and based on static routing. A IPv6 NAT
network is created between the HQ and the Branch C, tested and verified for the

establishment of the connectivity. The configuration command used for the configuration of
the router is given below:

end
Verification
For the verification of the configuration of the router and enabling communication
between the branches the configuration is verified by pinging the device connected with the
different router interface. The show command is used for the demonstration of the
configuration and IP address use for the configuration of the interface. The
HQ#ping AB12:1534:0:A::3
Type escape sequence to abort.

WIDE AREA NETWORK TECHNOLOGIES
Sending 5, 100-byte ICMP Echos to AB12:1534:0:A::3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms
The HQ router is pinged with the IPv6 address of the PC for testing the
communication between the PC and the router interface.
The configuration of the router for the branch is verified using the “show ip interface
brief” command and it shows the IP address assigned to the different interface of the router
and used for communicating with the other branch.

HQ#
The HQ router is configured with NAT such that it is able to communicate with the
branch C which is configured with IPv4 network address.

WIDE AREA NETWORK TECHNOLOGIES
The IP interface brief command is used for the configuration of the H router and the
details of the IP address assigned to the interface of the router is demonstrated in the above
screenshot.
The following screenshot is given for the demonstration of the ping tests and
verification of the connectivity between the server and the P connected with the router
interface of each of the branches.
