LACP and RouterBOARD 1100

Tue Dec 13, 2011 10:02 pm

Has anyone used the RouterBOARD 1100/1200 devices for LACP?

I'm going to be setting up multiple licensed links bonded together using LACP (802.3ad). Was wondering if anyone has done this using Mikrotik hardware.

Link specs are 4 x 11GHz 40Mhz channels bonded together for a 1Gbps microwave link.

I used this feature by Cisco 2960 and Mikrotik RB1100.
It works fine. one port used for Rx and the other used for TX. when ever one of them fails, the only one works as single connection(Failover).

If you want to do this, you need to have Mikrotik RB at the both side.

Yeah I was looking to use a pure Mikrotik solution.
            --- Wireless connection 1 ---
          /                               \
RB.A ===                                   === RB.B
          \                               /
            --- Wireless connection 2 ---
Wireless connection 1 and 2 would be bonded using 802.3ad using two RouterBOARD 1100s only. No other layer 2 devices.

Just looking for feedback to see if anyone has done this and how it performed.

LACP works, but you can't bridge that interface. The bridging disables the LACPDU packets and the bond fails. Or so all my testing seems to show.

I just tested this... Here's the specifics:

ROUTER A: RB1100AH ROSv.5.12 10.0.0.1/30
ROUTER B: RB1100AH ROSv.5.12 10.0.0.2/30

I have ether 1-3 bonded using 802.3ad with ARP for link monitoring Layer2+3 TxHashPolicy LACP rate is 30s. Same settings on both routers. IP address is assigned to the bonded interface.

Max RAW throughput I'm seeing is 999Mbps with three gigabit interfaces bonded. Throughput doesn't change as I disconnect reconnect the interfaces. This shows failover is working properly but it's not providing additional throughput.

Either that or the bandwidth test utility on RouterOS is capped to 1Gbps. I could try forcing 100Mbps on the interfaces to see if aggregate throughput is accomplished if that's the case.

Nevermind... i just realized the problem with using 802.3ad and a /30 subnet.

balance-rr works... i'm worried about what that might do for TCP sessions...

Was also able to get LACP to load balance and do failover using layer3/4 hash across a /30 point to point link. Although i think the 802.3ad standard only specifies layer2/3 hash so you'd need mikrotiks on both ends to do this.
