IPv6 Static NAT Configuration

IPv6 Static NAT Configuration

Hi ! everyone on today we are going to learn about IPv6 static NAT configuration. Which will be shown as screenshots to understand properly with topology as follows.

In this screenshot we can see two networks on Left hand side is IPv6 Network which represents in blue color and in the right hand side is IPv4 Network in pink color.

Step 1: First we should assign IPv6 and IPv4 address for configuration on Gateway-Router

On the screenshot we can see that the changed of state to up in green color for the Gateway-Router connecting both the switches.

Step 2: Configure IPv6 address by assigning on both the Routers

Router1

 Router2

Step 3: Now we should do IPv4 configuration on both the Routers

Router3

 Router4

Finally we can see that all the routers and switches are connected by the changed state to up in green colors.

Step 5: We should configure IPv6 static route on Router1 and Router2

Router1

Router1(config)#ipv6 route 2001:12::/96 2000:ABCD::1

Router2

Router2(config)#ipv6 route 2001:12::/96 2000:ABCD::1

Step 6: Then we should configure IPv4 static route on both the Routers

Router3

Router3(config)#ip route 20.0.0.0 255.0.0.0 10.0.0.1

Router4

Router4(config)#ip route 20.0.0.0 255.0.0.0 10.0.0.1

Step 7: Now test your Gateway-Router IP communication using ping command

Step 8: Configure both Static NAT for IPv4 to IPv6 transformation and IPv6 to IPv4 transformation on Gateway-Router

IPv4 to IPv6 transformation on Gateway-Router 

Gateway-Router(config)#ipv6 nat prefix 2001:12::/96

Gateway-Router(config)#ipv6 nat v4v6 source 10.0.0.2 2001:12::2

Gateway-Router(config)#ipv6 nat v4v6 source 10.0.0.3 2001:12::3 

IPv6 to IPv4 transformation on Gateway-Router

Gateway-Router(config)#ipv6 nat v6v4 source 2000:ABCD::2 20.0.0.2
Gateway-Router(config)#ipv6 nat v6v4 source 2000:ABCD::3 20.0.0.3

Step 9: Now we have to tell the Gateway-Router about NAT configuration

Gateway-Router>enable

Gateway-Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Gateway-Router(config)#interface FastEthernet0/0

Gateway-Router(config-if)#ipv6 nat

Gateway-Router(config-if)#exit

Gateway-Router(config)#interface FastEthernet0/1

Gateway-Router(config-if)#ipv6 nat

Gateway-Router(config-if)#exit

Step 10: Test the network communication by checking all the Routers

Finally, We can test communication from IPv4 network to IPv6 network using ping command

Router3

 Router4

Therefore, we have completed our lab session for IPv6 static NAT configuration in Cisco Packet tracer version 7.0. For more detailed information you can download our video and subscribe to our you tube channel "Young Cisco Certification Trainers".

SSH Configuration on Cisco Router using IPv6

SSH Configuration on Cisco Router using IPv6

Hi ! everyone on today we are going learn about how to configure SSH on cisco router using IPv6. Which is shown in screenshots given below for the following topology.

Step 1: First we should assign IPv6 address on both PCs

 PC0

 PC1

Step 2: Configure on Router0 using IPv6 and host PC 

 Now we can see the green color at connection which changed state to up. 

Step 3: Configure SSH on Router0 using IPv6

Step 4: Finally we can check SSH connection from host PC

Therefore, we have completed our lab session on SSH configuration on cisco router IPv6 in Cisco Packet tracer v 7.0. 

ACL Configuration on IPv6

ACL (Access Control List) Configuration on IPv6

Hi ! everyone today we are going to setup ACL configuration lab based on IPv6. These are the procedure to do step by step process given below by screenshots in detail.

Step 1: First we should arrange our network topology 

Step 2: Assign IP addresses for both PCs, FTP server and Web server

 PC0

 PC1

FTP Server

 Web Server

Step 3: Configure IPv6 on Router0

By configuration on Router0 with PCs, Web server and FTP server we can see the green color which is the changed state to up as shown below.

Step 4: Now we have to configure name based extended ACL on Router0

Router(config)#ipv6 access-list cisco
Router(config-ipv6-acl)#deny tcp host 2000::2 host 2001::3 eq 80
Router(config-ipv6-acl)#permit tcp host 2000::2 host 2001::2 eq 21

Note: Block Web Server for host 2000::2/64 but allow FTP Server.

Router(config-ipv6-acl)#permit tcp host 2000::3 host 2001::3 eq 80

Router(config-ipv6-acl)#deny tcp host 2000::3 host 2001::2 eq 21

Router(config-ipv6-acl)#exit

Note: Block FTP Server for host 2000::3/64 but allow Web Server.

Step 5: We should tell the Router interface about ACL name you have created above

Router(config)#interface FastEthernet0/0
Router(config-if)#ipv6 traffic-filter cisco in
Router(config-if)#exit

Step 6: We can check our configuration on host 2000::2/64 and 2000::3/64

We must be able to access FTP server but can’t access WEB server

Secondly we must be able to access Web server but can't FTP server.

Therefore, we have completed our lab session on ACL configuration on IPv6 in the Cisco Packet tracer v 7.0.

Deploy and Configure DHCPv6 for IPv6

Deploy and Configure DHCPv6 for IPv6

Hi ! everyone on today we are going to learn about how to deploy and configure DHCPv6 for IPv6 with simple explanation given below in the form of screenshots for the following topology. 

What do you meant by DHCPv6 ?

The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes and other configuration data required to operate in an IPv6 network. It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4.

Step 1: First we have to Assign IP address for DNS server

 Step 2: Configuration for IPv6 on Router0

Step 3: Configure DHCP for IPv6 on Router0

Step 4: Now we can check whether DHCP options on Clients PC

Therefore, we can see in this screenshot that shows DHCPv6 request is successful in this particular IPv6 lab session with Cisco Packet tracer v 7.0. 

Configuration IPv6 Tunneling over IPv4

Configuration IPv6 Tunneling over IPv4

Hi ! everyone on today we are going to learn about how to configure IPv6 tunneling over IPv4. This is a screenshot of our topology which is given below with detailed informations.

Step 1: Our first step is to assign IP addresses with the given values in PCs

Step 2: We should do configuration for Routers 1, 2 and 3

Router1

Router2

Router3

Through these steps we have changed the state to up which is in green color shown in screenshot below.

Step 3: Now we should make a tunnel for IPv6 to IPv4 configuration

To configure IPv6 to IPv4 tunneling we should first need to do create a tunnel interface on each dual-stack edge router.

First thing you should is to create a tunnel over Router1

After completing Router1 we should create a tunnel over Router3

Step 4: In this step we should configure IPv6 static Route on Router1 & 3

Router1

 Router3

Step 5: Now we should use ping command on PC1 to test the communication between both PCs 

Step 6: Now we can trace the path to destination IP to know exact route

Run the tracert command from PC0 

After PC0 running completed we should Run PC1

Step 7: We should see IPv6 route of Router1

 

Step 8: Finally we should see IPv4 route on Router1

Therefore, we have completed successfully our lab session on the topic how to configure IPv6 tunneling over IPv4 for our scenario with the Cisco Packet tracer v 7.0.
