Now…here we are…
finally we have succeded to make our backup links but I have some troubles…so I’m giving you this situation and I will hope someone to help me solve it 
1 link: AP 1 wifi card 1 EoIP 1 bridge 1 Ethernet / wifi mode ap-bridge → AP 2 wifi cards 2 EoIP 1 Bridge 1 Ethernet / wifi mode ap-bridge , station → same as second one → same → same → same and ends here.
2 link : AP 1 wifi card 1 EoIP 1 bridge 1 Ethernet / wifi mode ap-bridge → AP 2 wifi cards 2 EoIP 1 Bridge 1 Ethernet / wifi mode ap-bridge , station → same → same → same → AP 1 wifi card 1 EoIP 1 bridge 1 Ethernet / wifi mode station.
now the situation:
1st link and second link go to the same direction the only diference is that second link splits to another direction and returns to the 1st links 3rd point.
Now my question is how could I use the two links at the same time?
simple graphic:
1st link: A1--------R1--------R2--------R3---------R4---------E
2nd link: A2--------R1______r1_______R2--------R3/E/
A1=Mikrotik AP 1
A2=Mikrotik AP 2
R1= relay 1
R2= relay 2
R3 = relay 3
R4 = relay 4
E= end point
r1= split relay from R1 and connects back to R2
if you cant understand what do I want…please excuse me…its a bit hard to write it down
P.S.: can someone enlighten me should I use WDS instead of EoIP or just which is better for large performance?
