When a router is used you still do see the MAC address but only of the directly connected next hop/device. If another router, then it would change the headers

When a router is used you still do see the MAC address but only of the directly connected next hop/device. If another router, then it would change the headers appropriately.
- jonathanlydall 1y agoA router is connected to multiple networks and for networks running on Ethernet, yes, each device on those networks has a MAC address its interface connected to it. The headers of IP packets wouldn’t be affected by MAC addresses, Ethernet packets carry IP packets as their payload and would have their own headers as appropriate. A router’s job is essentially to “pass on” or relay IP packets based on its routing tables, they are what connect networks together.
