Hello,
Checking the VXLAN address table I realized that MLAG pair (Leaf 3/4) does not have the proper MAC Address associated when peering with MLAG peer (leaf 7/8)
Instead of having VX1 associated with the MLAG system-ID (deviation of system MAC address) of MLAG (Leaf 7/8) it seems to have obtained the system MAC address of Arista switch leaf7.

See output below.

Thanks,

Martin
