MikroTik

Hi All,

I am having issue with configuring Etherchannel(Bonding) between Cisco ASR 920 & Mikrotik CCR1036 router.

CIsco Router Config

end

ASR-920#show running-config interface po1

interface Port-channel1

end

ASR-920#show etherchannel summary

** Cisco to Mikrotik LACP link (Port-channel 1) is showing down.
Please help me to get this up and running..
Any help would be appreciated.
Thank You.

Hmm...
I don't see any obvious misconfiguration in your setup.
Just double-checked it with a bonding I have up and running here and the only differences I see is explicit LACP protocol assignment to the interfaces on the cisco side and plain layer2-hashing on the Tik side.

Here's my working config (Tik to catalyst 9300, but it should be universal since it's all iOS):

MikroTik config:
Cisco config:
-Chris

MikroTik is using the slow LACP PDU rate of 30s, what rate is the Cisco LACP channel using? If it's set for 1s, i'd reconfigure to 30 and retest.

When you configure port channels with EVC on the ASR 900, you must configure 1 EVC with untagged encapsulation and L2 protocol. For example:

interface Port-channel1
!
service instance 1 ethernet
encapsulation untagged
bridge-domain 1
l2protocol peer
!
