Route Distinguisher
--> Basically The Provider Edge Router is connected to so many CE Routers and they may have same networks .
--> If CE routers are using same network then it is difficult for BGP to identify which network is belong to which VRF.
--> Route Distinguisher simply adds 64 bit value to IP Address and makes it unique. When we add 64 bit value to IP address then it is called as VPNV4 address.
Route Target
--> Route Distinguisher basically used to make route unique, it does not specify to other router the route belongs to which VRF.
--> In order to specify this we will use Route Target.
