one of our customer has its router Cisco soho78

with one ethernet interface, when i issued the command SH CDP NEIGHBOR, he can see 3 nighbors through the ethernet interface , 2 routers and 1 switch, the ethernet interface is connected directly to only one router, it is not trunk ofcourse , as i know i can see by sh cdp only the directly connected neighbor , so how i see 3 on the same int. this is snap shot from the command outputDevice ID Local Intrfce Holdtme Capability Platform Port ID

You should only see one neighbor as the connection is point-to-point (soho78 to router). Which router is the directly connected router? And does it have bridging enabled or some other type of passthrough mode ?
