描述

Hello. I'm new to using SONiC. I read many documents, such as Architecture, Configuration, Design specs, etc but I don't clearly understand how a packet arrives in application containers such as BGP or LDP. What happens when a packet enters an interface until it leaves the switch? I don't understand how SDK and kernel interact. For example, when a new route arrives in one of the interfaces how will it convert to a kernel netlink message?
