GNS3-3tier with tier2 to tier3 for L3 BGP + tier1 to tier2 for L2 mlag

Hi, all:

as title, below is my topology. if I remove tor1 and tor2 tier 1 switch, spine and leaf architecture host can ping each other, but when I add tor1 and tor2 switch, server1 can reach 172.16.1.1 in leaf1 (is VLAN100). If I ping 172.16.2.101 will show can’t reach host, server1 to leaf01 is access mode, tor1 switch to leaf01 is trunk mode, I have no idea how to setting in leaf01 will drive bgp to route to another host, below is my setting, thanks.
