2.8 Implement IPv6Â
Configure IPv6 OSPF and EIGRP as per "IPv6 Topology Diagram"
Configure all Global unicast IP address to match 2001:YY:YY:SS::HH/MM
Where YY stands for your two-digits rack number, SS is the third octet of the IPv4 address of the same interface, HH is the fourth octet of the IPv4 address of the same interface, MM is the subnet mask and must be /128 for loopback interface and /64 for other interfaces.
Prefixes:
All loopbacks /128
Other interfaces /64
LOOPBACK addressing is 2001:YY.YY:3rd_IPv4::4th_IPv4/128
OSPF IPv6 addressing is preconfigured: 2001:1YY:YY:3rd_IPv4::4th_IPV4
EIBRP IPv6 addressing is preconfigured: 2001:YY:YY:3rd_IPv4::4th_IPV4
Part I
Enable OSPFv3 process 100 area 0 on vlan 68 of SW1 and SW3. Advertise lookbacks of SW1 and SW3 into this area.
Enable EIGRP YY on R1,R2, R4, SW3, and R5 matching the IPv4 EIGRP YY domain.Complete Soln:

Part II
Create a tunnel between R1 and R3 and address it 2001:YY:YY:13:13::X/64
Put R3 also in the IPv6 EIGRP YY domain
Redistribute between OSPFv3 and EIGRPv6 on SW3
Advertise Loopbacks on R3, R2, R4, and R1 into EIGRPv6
All router ID's should be stable and match the IPv4 router-IDs
Make sure you have FULL reachability on every IPv6 device including all loopbacks and your tunnel between R1 and R3.Complete Soln:
