Topology
Task 1
Enable connectivity between two IPv6 sites (presented in the topology diagram in green). Vlans 7, 9, 27, 79, 99, 107 should have connectivity to Vlan 215. The following stipulations should be considered while creating the solution to the problem:- The tunnel IPv6 address should use 2002:: prefix reserved for this method.
- You are allowed to use one static route on R1 and SW4 to solve the problem.
- Use RIPng on both sites, but there is not supposed to be RIPng prefix exchange between Vlan 215 and other Vlans on the remote site.
Solution
Task 1
Enable connectivity between two IPv6 sites (presented in the topology diagram in green). Vlans 7, 9, 27, 79, 99, 107 should have connectivity to Vlan 215. The following stipulations should be considered while creating the solution to the problem:
The method implies Automatic 6to4 tunnelling. Configure appropriate addressing scheme for all the Vlans in question. The method assumes the following prefix to be used:
Step 1
Create addressing scheme for all Vlans in question and the tunnel interface.
Border-Router-Prefix (based on the loopbacks) of R1 and SW4 (leading 0s in IPv6 address groups can be omitted).
Step 2
Configure the addresses on all interfaces in question and enable RIPng on those.

After checking neighbor-to-neighbor connectivity proceed to step 3.
Step 3
Configure tunnel and static routing between the sites.

! Since we only have two sites, we can use easy static routing like the one shown below:
!
ipv6 route 2002::/16 tunnel 0
!
ipv6 router rip CCIE
redistribute static metric 1

SW4 Config:
!
interface Tunnel0
no ip address

tunnel source Loopback0
tunnel mode ipv6ip 6to4
