When we are using L3 swicth with MLS-CEF feature enabled ( for speedy packet processing ). If a PC from VLAN_A sends "Ping" packet to PC in VLAN_B and gets a ping responce back showing the proper connectivity.
what are the MAC address involved in the process. In normal case PC A will send the packet to default gateway in this case VLAN_A ip address and corresponding VLAN MAC address. Then swicth will forward this packet to destination PC in the VLAN_B by ARP request and over-writing the farme destination by this MAC address. ( MAC of PC B ). But what is the source address of this frame which PC b will receive from switch.
In a normal router case fa0/0 will receive the frame from PC a, ( souce MAC of PC a and dest MAC of fa0/0 of router ) it will route this packet to fa0/1 and then to PC b. the destination frame will have source MAC of fa0/1 and PC B MAC address. How is this related to L3 switch source/dest MAC addreswise?
