== 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
