Update: Looks like it was bug in RouterOS v6.6, after upgrading to v6.7, everything is ok

hi everyone,

I have two CCR1036 router. Trying to set up trunk port on bonded interface and bridge it with untagged interfaces.
In the end I cant ping from Router1 to Router 2 via trunk port. Once I remove vlan interface from bridge port and set up IP address directly on vlan interface, everything seems ok.
Router1:

ros code

/interface bonding
add arp-interval=300ms arp-ip-targets=10.0.0.2 mode=active-backup name=sfp1-bond primary=sfp1 slaves=sfp1,eth3
/interface vlan
add interface=sfp1-bond name=vlan10 vlan-id=10
add interface=sfp1-bond name=vlan20 vlan-id=20
/interface bridge
add name=br-vlan10
add name=br-vlan20
/interface bridge port
add bridge=br-vlan10 interface=vlan10
add bridge=br-vlan10 interface=eth8
add bridge=br-vlan10 interface=eth7
add bridge=br-vlan20 interface=eth6 path-cost=4
add bridge=br-vlan20 interface=vlan20 path-cost=2
/ip address
add address=10.0.0.1/27 interface=br-vlan10 network=10.0.0.0
add address=10.1.0.1/27 interface=br-vlan20 network=10.1.0.0

Router2 has same config except:

ros code

/ip address
add address=10.0.0.2/27 interface=br-vlan10 network=10.0.0.0
add address=10.1.0.2/27 interface=br-vlan20 network=10.1.0.0
