Traffic loss after the F3 Linecard comes online after reload.
Traffic path is through the linecard which is getting reloaded. There is an alternate or redundant path (ECMP/PORT-channel member), through which the traffic can be routed in case if this linecard goes down or gets reloaded. When this Linecard comes online, traffic again gets hashed to this module and traffic loss might occur for some time.
Shut the interface on this linecard which are part of traffic forwarding
This issue is seen due to delay in HW programming due to selective VRF feature on F3 linecards.
