Which address is used for RA router advertisement messages?

link-local address
RA messages contain the link-local address and the layer-2 (MAC) address of the first-hop router. Servers can listen to these and use this information to auto-configure their default gateway.

MAC addresses only have meaning within an Ethernet network. Logically what happens at R1 is.

Where does the MAC address go on a NIC?

The network adapters or network interface cards always come with a MAC address which is fed into hardware, usually in read-only memory (ROM), or BIOS system. The physical address is stored into the NIC by its manufacturer, that is why this address is also called a burned-in address (BIA) or ethernet hardware address.
