1.1(0.718a)

Description (partial)

Symptom:
Traffic between application endpoint groups and external Layer 3 networks on different leafs is dropped if multiple external Layer 3 networks are configured in the same context.

Conditions:
This can happen when multiple L3Out are deployed in the same private network (fvCtx) in the following scenario:
Application EPG A deployed on leaf1, in contract with L3Out A on leaf 2
L3Out B deployed on leaf1. Due to implicit deny rules for this L3Out, this will drop traffic on the same context between the application EPG and the other L3Out.
