Detailed Description

This class holds Evpn state for a particular <S,G> at any given time.

In Evpn state machinery, different types of routes are sent and received at different phases of processing. This class holds all relevant information associated with an <S,G>.

This is a refcounted class which is referred by DB States of different routes. When the refcount reaches 0, (last referring db state is deleted), this object is deleted from the container map and then destroyed.

global_ermvpn_tree_rt_ This is a reference to GlobalErmVpnRoute associated with the ErmVpnTree used in the data plane for this <S,G>. This route is created/updated when ErmVpn notifies changes to ermvpn routes.

states_ This is the parent map that holds 'this' EvpnState pointer as the value for the associated SG key. When the refcount reaches zero, it indicates that there is no reference to this state from of the DB States associated with any Evpn route. Hence at that time, this state is removed this map states_ and destroyed. This map actually sits inside the associated EvpnProjectManagerParitition object.
