How to setup MLAG on mikrotik switches

Random notes:

  • Between mikrotik devices they supposedly use ICCP similar to Cisco and Juniper:
    • https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/cether/configuration/15-s/ce-15-s-book/ce-iccp-multichass-vlan-red.pdf
    • TODO: Fill in juniper docs.
  • Currently there is no wireshark dissector for the mikrotik version (or any it seems).

Odd things seen:

  • After a reboot of one of the peer switches or the ICCP link drops it takes aprox 8 minutes to re-establish connectivity.
    • MLAG state is connected.
    • Client sees both links as active.
  • Done

Bugs to investigate if fixed:

  • https://forum.mikrotik.com/viewtopic.php?t=185237#p928292
  • https://forum.mikrotik.com/viewtopic.php?t=195383 - To see if we can get the info from Mikrotik or if it will have to be reverse engineered.
