i have topology as below:

STP protocols.png

I had config as below:

Ex2200-1#set protocol rstp bridge-priority 4K


Ex2200-2#set protocol rstp bridge-priority 16K

Ex2200-2#set protocol rstp interface ge-0/0/5.0 cost 40000



Ex3300#set protocol rstp bridge-priority 12K

EX3300#set protocol rstp interface ge-0/0/1.0 cost 21000


But, my result: interface ge-0/0/1 (EX3300)= BLK; interface ge-0/0/5 (EX2200-2)=D (FWD). I want to set interface ge-0/0/1 (EX3300)=D and interface ge-0/0/5 (EX2200-2)=BLK. Pls guide me!
