== Device Configuration (Dual Stack/IPv6) ==

As our network is working well in IPv4 mode lets enable dual stack. This is very easy as its only configuring the interface IP addresses and IPv6 routing.

You can refer the following [=#point1 table] for assign Interface IPv6 addresses. In the following IPv6 addresses replace the '''PQRT''' segment with the IPv6 block assign to you. You can find your IP block from here.

=== Core Network Layer ===
First Configure the !CampusCore with IPv6 addresses and then move in to FacACore and FacBCore.

==== !CampusCore ====
 - Login to CampusCore? device. Give your console port password (class password)
 - Go to config mode from user mode. Give your enable password (class password)
 - Assign the IPv6 Address to the VLAN interface
{{{
CampusCore(config)#interface vlan 2
CampusCore(config-if)# ipv6 address 2401:dd00:PQRT:2::FFFF/64 
CampusCore(config-if)# exit
CampusCore(config)#interface vlan 255
CampusCore(config-if)# ipv6 address 2401:dd00:PQRT::FFFE/64 
CampusCore(config-if)# exit
}}} 
 - Next we have to configure unicast routing in the Switch
{{{
CampusCore(config)#ipv6 unicast-routing
}}}
 - Make sure you '''save''' the configurations to start-up

Then we will configure FacACore with it's IPv6 Addresses

==== FacACore ====
 - Login to FacACore device. Give your console port password (class password)
 - Go to config mode from user mode. Give your enable password (class password)
 - Assign the IP Address to the VLAN interface and enable unicast routing
{{{
FacACore(config)#interface vlan 2
FacACore(config-if)#ipv6 address 2401:dd00:PQRT:2::A/64
FacACore(config-if)#exit
FacACore(config)#interface vlan 10
FacACore(config-if)#ipv6 address 2401:dd00:PQRT:A110::FFFF/64
FacACore(config-if)#exit 
FacACore(config)#ipv6 unicast-routing
FacACore(config)#exit
FacACore#write
}}}

==== FacBCore ====
 - Repeat same to configure FacBCore
{{{
FacBCore(config)#interface vlan 2
FacBCore(config-if)#ipv6 address 2401:dd00:PQRT:2::B/64
FacBCore(config-if)#exit
FacBCore(config)#interface vlan 20
FacBCore(config-if)#ipv6 address 2401:dd00:PQRT:B220::FFFF/64
FacBCore(config-if)#exit 
FacBCore(config)#ipv6 unicast-routing
FacBCore(config)#exit
FacBCore#write
}}}
 - Finally Verify the connectivity
    * Go to FacACore device
    * Go to privileged mode and ping !CampusCore? and FacBCore
{{{
ping 2401:dd00:PQRT:2::FFFF
ping 2401:dd00:PQRT:2::B
}}}
 - You should get a positive reply with "!!"

=== PC Auto Configuration ===
Log in to your Dept1PC and check its IP address by issuing '''ifconfig''' in console. You may notice that there is a new IPv6 address auto configured with the VLAN 10 prefix.
 - Try ping IPv6 gateway
{{{
ping6 2401:dd00:PQRT:A110::FFFF
}}}
 - you will get a positive result

Check the same with Dept2PC. But now it should show an address from VLAN 20 prefix. Check connectivity by ping6 VLAN20 interface ipv6 address.

=== Connecting LAN to the Router ===
Now you have done LAN interface configuration. Let's start routers Configuration.
 - Login to !BorderRt? Router and switch to config mode
 - Router's IP allocation is as follows. You can get your Router's IP address from here
||= Interface Name =||= IP Address =||
||Fast Ethernet 0/0 ||2401:dd00:PQRT::FFFF/64||
||Fast Ethernet 0/1 ||<Your Routers WAN IPv6>||
 -  Let's configure the LAN port (fa 0/0)
{{{
BorderRt(config)#interface fastEthernet 0/0
BorderRt(config-if)#ipv6 address 2401:dd00:PQRT::FFFE/64
BorderRt(config-if)#exit
}}}
 - Configure the WAN port (fa 0/1)
{{{
BorderRt(config)#interface fastEthernet 0/1
BorderRt(config-if)#ipv6 address 2401:dd00:6::XXXX/64
BorderRt(config-if)#exit
BorderRt(config)#ipv6 unicast-routing
BorderRt(config)#exit
BorderRt#write
}}}
 - You have successfully finished connecting !CampusCore? to the !BorderRt? router. Let's verify the connectivity using the ping command.
