Bounding and active-backup configuration.

RouterOS Forwarding Protocols
1

Hello all.
Does anybody can provide me right example about bounding configuration.
I Have two Core switches. I would like to setup ROS box and connect it to different switches.
ethernet 1 should be “Master”, but for some reasone Master interface is ethernet2. Why?
What settings for slaves= and primary= are correct?

[admin@MikroTik] > interface bonding print
Flags: X - disabled, R - running
0 R name=“bonding1” mtu=1500 mac-address=00:0C:42:5A:74:B6 arp=enabled
slaves=ether2,ether1 mode=active-backup primary=ether1
link-monitoring=mii-type1 arp-interval=100ms mii-interval=100ms
down-delay=0s up-delay=0s lacp-rate=30secs transmit-hash-policy=layer-2

I’m going to setup some Vlans on bounding interface, Does it work correctly?
I’m going to use thouse Vlans for OSPF and BGP (with bfd support). Can be there problem with that?

actually, it’s bonding, not bounding =)

yes, VLANs work perfectly over bonding interface

about what Master interface do you say?..

Ok, thank you for answers.
The one thing remained not clear to me:
I need, that a traffic goes only through one interface (in my case ethernet1).
From the Manual:

active-backup
This mode uses only one active slave to transmit packets. Different slave becomes active only if primary slave fails.
I’ve attached configuration …

а) Trunk has only Vlan 2. - Why then we have difference between counters on Trunk and Vlan2 interfaces?
b) Why does a traffic goes on both interfaces (Ethernet 1 and 3)?

Does something wrong with my configuration or it’s a bug for v. 5.beta2?

it’s RX traffic - so look at the other side of the link…
