Lab 208 - IPv6 NAT-PT

Prerequisites: CCNP level skills.

Note!
If interfaces have not been configured with IPv6 addresses yet, use fc00:1:1::/64 as the network-ID and ::x, as a host ID (where x=router-ID).

Topology

Pic 1. IPv6 Topology Diagram.

Task 1
Vlan 113 runs IPv4 protocol (203.0.113.0/24). Configure R3 in such a way that 
R2 should ping 2001::CB00:71FE to reach 203.0.113.254 address (BB1).
You are allowed to use one static route on R2 to accomplish the goal.

Solution

Task 1
Vlan 113 runs IPv4 protocol (203.0.113.0/24). Configure R3 in such a way that 
R2 should ping 2001::CB00:71FE to reach 203.0.113.254 address (BB1).
You are allowed to use one static route on R2 to accomplish the goal.

R2 Config:
!
ipv6 route 2001::/96 FC00:1:1:20::3
!

R3 Config:
!
interface Serial1/0
 ipv6 address FC00:1:1:20::3/64
 ipv6 nat
 ipv6 ospf 1 area 13
!
interface FastEthernet0/0
 ip address 203.0.113.3 255.255.255.0
 speed 100
 full-duplex
 ipv6 nat
!
!
ipv6 nat v6v4 source FC00:1:1:20::2 203.0.113.2
ipv6 nat v4v6 source 203.0.113.254 2001::CB00:71FE
!
ipv6 nat prefix 2001::/96
