Internet Protocol version 6 (IPv6)

Basic IPv6 Network configuration in Packet Tracer:

The Aim of configuration:

  1. On the routers configure basic security with hostnames, console and vty passwords, banner message of the day, and enable password encryption
  2.  On the routers configure link-local and global unicast IPv6 addresses with network prefix lengths
  3.  On the routers configure static IPv6 default routes
  4.  On the PCs configure static IPv6 addresses with network prefix lengths and a gateway address
  5. The aim is to configure the network with IPv6 addressing and be able to ping from PCA to PCB using their IPv6 addresses

Configure the routers:

  1. line console 0, line vty 0 4,password: cisco (encrypted),enable: class (encrypted)
  2. hostnames: R1, R2, banner: No unauthorised access allowed!
  3. Interface G0/0, G0/1: IPv6 Global unicast addresses.
  4. R1(g0/1: 2001:DB8:ACAD:1::1/64, g0/0: 2001:DB8:ACAD:2::1/64)
  5. R2 (g0/0:2001:DB8:ACAD:2::2/64, g0/1:2001:DB8:ACAD:3::1/64)
  6. IPv6 Link-local addresses: (R1) FE80::1 link-local, (R2) FE80::2 link-local
  7. Interface descriptions:R1 the descriptions are: toR2, toLAN, R2 the descriptions are: toR1, toLAN
  8. IPv6 Routing: IPv6 routing needs to be enabled on the routers,R1 and R2 need an IPv6 static default route to ::/0 via the next hop IPv6 address
  9. PCA and PCB: Static IPv6 address and network prefix length                                           (PCA: 2001:DB8:ACAD:1::10/64, PCB: 2001:DB8:ACAD:3::10/64)
  10. PCA: Default Gateway: FE80::1, PCB : Default Gateway: FE80::2
