Hello,
i have this setup similar here:

ros 7.8
my setup at the moment:
switch1:
/interface bridge
add ingress-filtering=no name=bridge1 vlan-filtering=yes
/interface vlan
add interface=bridge1 name=vlan1 vlan-id=1
/interface bonding
add mode=802.3ad name=mlag-bond slaves=qsfp28-1-1,qsfp28-2-1

/ip route
add disabled=no dst-address=0.0.0.0/0 gateway=10.1.2.1 routing-table=main suppress-hw-offload=no
my problem:
i ping from my client below the servers above.
that works but with 2-8% packet loss.
it seems that the arp table of both crs510 is not in sync or arp times out.
i tried the bond from crs326 to the both crs510 to switch from 802.3ad to active backup.
its a litte bit better. but from my client i can’t after that change the ip auf the switch to never reach.
whats wrong ?
Thanks
Thomas
