[j-nsp] routing updates between PFEs and Kernal

[Good One]

We started using MX-480 and I came to know that each DPC has four PFEs. Now a question comes to mind that how the chemistry of routing updates in between PFEs and RE(kernel) is being done. If kernel routes are being exported to PFEs, does it means that each PFE contains a full routing table? 
So if you have five DPCs than you have 20 PFEs and you are exporting kernel routes to all 20 PFEs and each PFEs is having a best route in the forwarding table.
