We have SVI vlan on layer 3 core switch A.
this switch has connection to ASA and also to another B Layer 3 switch.
B Layer 3 switch connects to Layer 2 switch which has this vlan.
Need to undertsand traffic flow from user PC to Switch A.
Switch B has default route which is static to fw for subnet of vlan.
Now traffic goes from layer 2 switch to core Switch B then it has static route for that vlan which is ASA as next hop.
now traffic comes to ASA from there it goes to core Switch B which has SVI Vlan in it.
Also Core Switch A and B has trunk connection which carries that vlan.
Need to know if return traffic from core Switch A comes via ASA or by Switch B?
How can i check this?
