Based on this url https://www.juniper.net/documentation/en_US/junos/topics/topic-map/mc-lag-high-availability-l3-vrrp-macsync.html#id-example-configuring-multichassis-link-aggregation-for-layer-3-unicast-using-mac-address-synchronization
"You can choose either to synchronize the MAC addresses for the Layer 3 interfaces of the switches participating in the MC-LAG, or you can configure Virtual Router Redundancy Protocol (VRRP), but you cannot configure both at the same time."
It said cannot use at same time. But when i look on config on that url the "mcae-mac-synchronize" was tie into irb interface. So it should not have issue right if we mix in one MC-LAG interface with VRRP and mcae-mac-synchronize with different irb? For example irb.40 i'm use VRRP method and irb.50 i'm use mcae-mac-synchronize method.
Thanks and appreciate any feedback.
