Explanation:

CL3 – CL2 – drop on forward path by core1 cause match VLAN 20 and CL3 not CL1 as SRC IP

CL1 – CL2 – pass – no ACL cause forwarded by Access2

SR2 – CL2 – pass on forward path by core1 cause match VLAN 10

Drop on return path by core1 cause match VLAN 20 and no CL1 as SRC IP

SR1 – CL1 – pass on forward path by core1 cause match VLAN 10
