Vlans + interface bonding

[winnerke]

i’ve got 2 RB750GR3 routerboards and i’m trying to make a small lab with these.
i want to bond 2 ports and trunk them. and after that trunk the other ports to the servers.

i tried many things but didn’t get anything to work.
how do i setup the vlans on the bonding , and connecting them at my other port that needs to trunk too

Bonding is really the least of your problems. As long as you remove the physical interfaces from their master interface (make them master=none), then create the bonding interface with the 2 ports, it will work. Hook them up together and you should see the bonding interfaces come up.

Your VLAN layout makes setup tricky, but it’s possible (or you might consider trying the new bridge code in 6.41). I decided to go another route and get a Cisco (then Juniper) switch to attach to my Gr3. Here’s what you have to read:

https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN

I just made all VLAN interfaces use “bonding1” (My bonded interface) go down to the Cisco, where setting up vlan trunk and access ports is much more straightforward.

Then on the Cisco you do something like:

int po1
switchport mode trunk
switchport trunk allowed vlan 10,20,30,40
switchport trunk native vlan 99 (or anything that you aren’t using)

int g0/1
channel-group 1 mode active
int g0/2
channel-group 1 mode active

And there you go, all vlans now exist on the Cisco and you can either make more trunk ports or access ports to whatever vlan you want. Easy.

I paid all of $45 to get a used 2960 with 48 10/100 ports and 2 gigabit ports shipped to my door. $100 for a gigabit PoE 24 port Juniper. Both have a learning curve but it’s time well spent if you’re going to be a network person. I like MikroTik as the router, and Cisco/Juniper as layer 2 devices. It’s a nice setup.

thanks for your bright answer , but i actually need to use this setup , there’s no switching to Cisco. i would love to use cisco for this but i have to use the mikrotik !

So 2 things then:

1. Invest the time in learning the “old” way, creating a bunch of bridges across physical interfaces and vlans as the link I posted shows.

2. Learn the “new” way in 6.41rc which will be the way things work once that code is released. I haven’t tried it yet.

Turns out there isn’t much to learn. The new code just decides in the background if there is hardware bridging ability, and there is a matrix of functions that affect if hardware bridging can work.
