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
