Load Balance Dengan Policy Routing

ini adalah load balance, tapi bisa juga di sebut sebagai policy routing, jadi kalau ada 1 link ingin di ambil link lokalnya saja, bisa di lempar ke link 1, contoh kasus aku ada 3 wisp, tapi aku ingin ambil 3 line inter-nya dari ke 3 line ini, tapi lokalnya aku lempar ke wisp 1 saja,

1. pastikan ip2nya sudah siap ya 

Code:

/ip address> pr
Flags: X - disabled, I - invalid, D - dynamic 
 #   ADDRESS            NETWORK         INTERFACE                                
 0   3.3.3.8/27         3.3.3.0         ns                                       
 1   13.13.13.1/27      13.13.13.0      ether3                                   
 2   1xx.1xx.6x.10x/27  1xx.1xx.xx.xxx   ns                                       
 3   172.10.1.1/30      172.10.1.0      monitoring                               
 4   100.100.100.17/27  100.100.100.0   ns                                       
 5   10.10.10.26/24     10.10.10.0      ns

2. lalu import dahulu nice dari web _http://mikrotik.co.id/getfile.php?nf=nice.rsc

3. kita langsung ke mangle, ingat kuncinya di sini...

Code:

Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=prerouting action=mark-connection new-connection-mark=con-iix 
     passthrough=yes dst-address-list=nice 

 1   chain=prerouting action=mark-routing new-routing-mark=routing-iix

     passthrough=yes connection-state=new dst-address-list=!nice 
     connection-mark=!con-iix nth=3,3 

 3   chain=prerouting action=mark-routing new-routing-mark=salak m passthrough=n>
     in-interface=ether3 connection-mark=salak m 

 4   chain=prerouting action=mark-connection new-connection-mark=salak 71

 8   chain=prerouting action=mark-packet new-packet-mark=packet-iix 
     passthrough=no connection-mark=con-iix 

 9   chain=output action=mark-packet new-packet-mark=packet-iix passthrough=no 
     connection-mark=con-iix 

10   chain=prerouting action=mark-packet new-packet-mark=packet-int 
     passthrough=no 

11   chain=output action=mark-packet new-packet-mark=packet-int passthrough=no

4. kita ke ip route..

Code:

 pr de
Flags: X - disabled, A - active, D - dynamic, 
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, 
B - blackhole, U - unreachable, P - prohibit 
 0 A S  dst-address=0.0.0.0/0 gateway=3.3.3.1 
        gateway-status=3.3.3.1 reachable bridge1 distance=1 scope=30 
        target-scope=10 routing-mark=routing-iix 

 1 A S  dst-address=0.0.0.0/0 gateway=10.10.10.1 
        gateway-status=10.10.10.1 reachable bridge1 distance=1 scope=30 
        target-scope=10 routing-mark=salak m 

 2 A S  dst-address=0.0.0.0/0 gateway=3.3.3.1 
        gateway-status=3.3.3.1 reachable bridge1 distance=1 scope=30 
        target-scope=10 routing-mark=salak 71 

 3 A S  dst-address=0.0.0.0/0 gateway=100.100.100.1 
        gateway-status=100.100.100.1 reachable bridge1 distance=1 scope=30 
        target-scope=10 routing-mark=jagakarsa 

 4 ADC  dst-address=3.3.3.0/27 pref-src=3.3.3.8 gateway=bridge1 
        gateway-status=bridge1 reachable distance=0 scope=10 

 5 ADC  dst-address=10.10.10.0/24 pref-src=10.10.10.26 gateway=bridge1 
        gateway-status=bridge1 reachable distance=0 scope=10 

 6 ADC  dst-address=13.13.13.0/27 pref-src=13.13.13.1 gateway=ether3 
        gateway-status=ether3 reachable distance=0 scope=10 

 7 ADC  dst-address=100.100.100.0/27 pref-src=100.100.100.17 gateway=bridge1 
        gateway-status=bridge1 reachable distance=0 scope=10 

 8 ADC  dst-address=115.124.68.96/27 pref-src=115.124.68.108 gateway=bridge1 
        gateway-status=bridge1 reachable distance=0 scope=10 

 9 ADC  dst-address=172.10.1.0/30 pref-src=172.10.1.1 gateway=bridge1 
        gateway-status=bridge1 reachable distance=0 scope=10

5. nat nya

Code:

 pr
Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=srcnat action=masquerade out-interface=alat 1 
 1   chain=srcnat action=masquerade out-interface=alat 2
 3   chain=srcnat action=masquerade out-interface=alat 3

dalam nat sebenernya alat itu bisa di kategorikan sebagai modem 1 2 3. dalam praktek saya ini hanyya menngunakan 1 cpe  tapi narik 3 line sekaligus 

dalam praktek ini bisa saja punya 3 line speedy, 1 speedy ingin di pakai link lokalnya saja, sedangkan 2 line lagi di ambil 22 nya inter maupun lokal,
