Mlag / crs518-16xs-2xq-rm

Hello, I am configuring MLAGU on CRS518-16XS-2XQ-RM devices. And I came across a problem where I don’t know much, because the information is varied. How to configure the bridge correctly? I couldn’t find this mentioned anywhere in the official documentation. If I left the default configuration I would use the same MAC in the admin-mac field that the bridge has set, but apparently both devices are supposed to have the same MAC set in “admin-mac”. Has anyone solved a similar problem ?

Configuration:

/interface bridge
add name=bridge-cluster protocol-mode=rstp priority=0x1000 vlan-filtering=yes
set bridge-cluster auto-mac=no admin-mac=[/interface get bridge-cluster mac-address]
or
/interface bridge
add name=bridge-cluster protocol-mode=rstp priority=0x1000 vlan-filtering=yes
/interface bridge set bridge-cluster auto-mac=no admin-mac=02:AA:BB:CCD:02

/interface bonding
add lacp-rate=1sec mode=802.3ad name=bond-peer slaves=qsfp28-1-1,qsfp28-2-1 transmit-hash-policy=layer-2-and-3
add lacp-rate=1sec mlag-id=100 mode=802.3ad name=bond-firewall slaves=sfp28-14,sfp28-15

/interface bridge port
add bridge=bridge-cluster interface=bond-peer pvid=99
add bridge=bridge-cluster edge=yes frame-types=admit-all interface=bond-firewall
add bridge=bridge-cluster edge=yes interface=ether1

/interface bridge vlan
add bridge=bridge-cluster tagged=bond-peer,bond-firewall vlan-ids=10
add bridge=bridge-cluster untagged=bond-peer vlan-ids=99
add bridge=bridge-cluster tagged=bond-peer untagged=ether1 vlan-ids=1

/ip neighbor discovery-settings
set discover-interface-list=all

/ip settings
set max-neighbor-entries=8192

/ipv6 settings
set disable-ipv6=yes max-neighbor-entries=8192

SW01

/interface bridge mlag # priority=0 = master, priority=50 = secondary
set bridge=bridge-cluster peer-port=bond-peer priority=0

/system identity
set name=SW01

SW02

/interface bridge mlag # priority=0 = master, priority=50 = secondary
set bridge=bridge-cluster peer-port=bond-peer priority=50

/system identity
set name=SW02

None of mine have the same admin MAC. Where does it say that?

Once the MLAG is up, they’ll use the MAC address of the primary switch automatically.
