Comment 0 for bug 1715176

1]. Created a in-network-nat ECMP SVC between ctest-left_ctest-TestECMPFeature-72816639-24666446
(59.55.203.0/24) and ctest-right_ctest-TestECMPFeature-72816639-52542641(114.201.64.0/24).

2]. None of the Internal RIs are created and the SVC is not working.

3]. The following tracebacks are seen in the contrail-api log:
