Introduction:
In this lab, you will perform basic configuration of EIGRP for IPv6 routed protocol. Begin with the assignment of router-id then enable eigrp on the interfaces, disable the unnecessary advertisement of hello packets and finally tweak eigrp timers to improve convergence.
Topology:
Procedures:
Step1: Assign router-id to the routers in the topology beginning with the Core1.
Core1(config)#ipv6 router eigrp 15
Core1(config-rtr)#eigrp router-id 0.0.0.1
List of Router IDs:
Core1: 0.0.0.1
Core2: 0.0.0.2
HQ-DR1: 0.0.3.1
HQ-DR2: 0.0.3.2
HQ-R1: 0.0.3.11
DR1: 0.0.5.1
DR2: 0.0.6.2
EDR1: 0.0.4.1
EDR2: 0.0.4.2
ER1: 0.0.4.11
ER2: 0.0.4.12
BR1: 0.0.17.1
BR2: 0.0.18.2
BR3: 0.0.19.3
Step2: Determine which interfaces have to participate in the EIGRP for IPv6.

Step3: Using interface range command enable EIGRP for IPv6 on the group of qualified interfaces.
Core1(config)#interface range g0/0-6
Core1(config-if-range)#ipv6 eigrp 15
Core1(config-if-range)#end
Step4: Verify that interfaces participate in EIGRP domain as intended.

Step5: Repeat steps 1 through 4 on the rest of the routers in the topology.
Step6: Verify EIGRP for IPv6 neighborship between all participating routers.
