I think there is better ways to accomplish what you want to do.  Tend to bring 
in the bad with the good when bonding and wireless has plenty bad to bring in.

Greetings,



I'm looking at a configuration to set up bonding between two Mikrotik 

routers (CCR1009 and RB2011), using two separate wireless links between 

them (external radios).



I am concerned about one of the links having an issue where it stays 

linked, but stops passing traffic.



Which bonding driver would be best suited to providing maximum 

availability? Bonded capacity is not required, but the links aren't the 

same speed; so I'd want to prefer the faster link if non-aggregated 

capacity is required.



It seems like any method which only supports MII monitoring is out, 

because the MII link wouldn't drop (it's Ethernet to the radio); which 

rules out 802.11ad, active-backup, and balance-tlb.



broadcast seems like it would be limited to the slower link, rather than 

the faster link.



balance-rr states that it requires equal bandwidth links.



This appears to only leave balance-xor and balance-alb. It seems like 

balance-alb is most likely the best choice.



I am also unclear on how the ARP availability mechanism judges a port to 

be available. I think that I would want to assign a unique probing 

address to each port on each end of each router, and have those IP 

addresses (one per port) set in the arp-ip-targets list? This should 

allow the router to know which specific ports work, and which don't?



Thanks,
