hi. i have 3 mikrotik routers.as you can see in attached image, router that i created bridge on it have ping to 2 another router but other router can only ping this router and cant ping next router.
in mik2 check the bridge filter of you isolation ports by drop forward , or in bridge port check if horizon is 1.
there is no isolation and bridge firewall.horizon is blank and i tested 1 . no result.
i changed promiscuous mode to accept in switch properties of vmware esxi and problem solved.
