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 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.

VLAN	VLAN Name	Device Name	VLAN Interface IP
2	Core	CampusCore	2401:dd00:PQRT:2::FFFF/64
		FacACore	2401:dd00:PQRT:2::A/64
		FacBCore	2401:dd00:PQRT:2::B/64
10	FacA	FacACore	2401:dd00:PQRT:A110::FFFF/64
		Dept1PC	no interface IP
20	FacB	FacBCore	2401:dd00:PQRT:B220::FFFF/64
		Dept2PC	no interface IP
255	Router Connection/Public IP	CampusCore	2401:dd00:PQRT::FFFE/64

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
