Bonding Mirkotik

Bonding is a technology that allows to aggregate multiple ethernet-like interfaces into a single virtual link, thus getting higher data rates providing failover.
Quick setup guide
Router 1

[Admin @ Router1]> interface bonding menambahkan budak = ether1, ether2

router 2

[admin@Router2] interface bonding> add slaves=ether1,ether2

add addresses to bonding interfces

[admin@Router1] ip address> add address=172.16.0.1/24 interface=bonding1
[admin@Router2] ip address> add address=172.16.0.2/24 interface=bonding1

Test the link from Router1:

[admin@Router1] interface bonding> /pi 172.16.0.2
172.16.0.2 ping timeout
172.16.0.2 ping timeout
172.16.0.2 ping timeout
172.16.0.2 64 byte ping: ttl=64 time=2 ms
172.16.0.2 64 byte ping: ttl=64 time=2 ms

Bonding interface needs a couple of seconds to get connectivity with its peer.
