All devices are running RouterOS v7.1.1.
If we are running it like on the picture, ping from upstream router will stop after few moments, only way to restore the communication is disabling half of the LACP towards client, thus forsing data through right CRS305.
Upstream router is untagged on port sfp-sfpplus3 and client is on bond0 using vlan1.
MLAG bridge is using untagged vlan777 for ICCP traffic and tagged vlan1 on bonding towards client as well as untagged vlan1 for sfp-sfpplus3.
Is there a way to force traffic through the interconnect between CRS305s ? Because this setup simulates two different upstream providers or link failure.
We have tested same setup on Arista switches with MLAG and they transfer the traffic using interconnect link.
