Figure 1 shows the EIGRP for IPv6 network topology. The serial links in the topology have the same bandwidth that is used in the EIGRP for IPv4 topology.
Similar to the previous scenario for IPv4, R3 has two EIGRP equal-cost routes for the network between R1 and R2, 2001:DB8:CAFE:A001::/64. One route is via R1 at FE80::1 and the other route is via R2 at FE80::2.
Figure 2 shows that the EIGRP metrics are the same in the IPv6 routing table and in the IPv4 routing table for the 2001:DB8:CAFE:A001::/64 and 172.16.3.0/30 networks. This is because the EIGRP composite metric is the same for both EIGRP for IPv6 and for IPv4.
Note: EIGRP for IPv4 and IPv6 can also balance traffic across multiple routes that have different metrics. This type of balancing is called unequal-cost load balancing.
