This is based on @donaldsharp's work The current code base is the struct bgp_node data structure. The problem with this is that it creates a bunch of extra data per route_node. The table structure generates ‘holder’ nodes that are never going to receive bgp routes, and now the memory of those nodes is allocated as if they are a full bgp_node. After splitting up the bgp_node into bgp_dest and route_node, the memory of ‘holder’ node which does not have any bgp data will be allocated as the route_node, not the bgp_node, and the memory usage is reduced. The memory usage of BGP node will be reduced from 200B to 96B. The total memory usage optimization of this part is ~16.00%.
