Nexus 7000 EIGRP Equal Cost MultiPath not working

We have 2 Nexus 7000 running NX-OS version 6.2.8a and have configured EIGRP between them. Equal Cost Multi Path seems to be not working when we tried to verify the interface statistics even if we are seeing that both routes are installed in the routing table.

Hi John-

Did you even resolve the ECMP with EiGRP issue?  Are you running Active/Active today?
