This seems to be quite obvious to me. If the packet is generated from the 2500 router , it knows that 88.1.0.0/16 is on serial 0 (directly connected). The packet reaches 2611 which has 88.1.77.1 directly conected. The return packet can also flow as 88.1.201.1 is directly conected. But this is true only if the source of the packet is 88.1.201.1 (s0 of 2500). This is bcoz any other source will not be known to 2611 and the return packet will fail.

There isn't any dynamic or static routing except a default route on 3550 to 2611. I can't understand this. Does I misunderstand the function of proxy-arp ? another related question, what's the real function of proxy-arp on serial interface ? thanks!
