it should be on back of router!
In OSPFv3, the router ID is determined by selecting the highest IP address assigned to an active interface on the router. If no interfaces are available, OSPFv3 will use the highest IPv4 address among the router's loopback interfaces, if configured. If no loopback interfaces are present, and no active IP addresses are available, the router ID remains undefined until one is assigned or the router is restarted. The router ID is essential for uniquely identifying the OSPFv3 router within an OSPF network.
The highest MAC address among the active interfaces of the network will be used. There will be no router ID until a loopback interface is configured. The highest IP address among the active FastEthernet interfaces that are running OSPF will be used. The highest IP address among the active interfaces will be used.
Configure the router ID on both routers. Configure the R2 router interfaces for area 0. Configure a loopback interface on both routers. Configure the proper subnet masks on the router interfaces.
To find your Mac's ID (also known as the MAC address), go to "System Preferences" and select "Network." Choose the network interface you're using (like Wi-Fi or Ethernet), then click on "Advanced." In the "Hardware" tab, you will see your MAC address listed as "MAC Address" or "Wi-Fi Address." Alternatively, you can open the Terminal and type ifconfig, and look for the "ether" line under the relevant network interface.
No, MAC addresss and IP address are not the same. MAC addresses are "hard-coded" into the Network Interface Card (NIC) and only ID that individual card. The IP address is software generated and ID's both the network and the individual host.
yes! you can!
That is a MAC( Media Access Control ) address. Its the physically assigned hexadecimal address on a Network Interface Card. The first half indicates the manufacturer ID while the other half is the NIC ID

The Vendor ID (OUI) of the Sources NIC is the unique organizational identifier assigned to the manufacturer of the network interface card by the IEEE. The OUI is the first three bytes of the MAC address assigned to that device.
There are a few ways:Use a password.Lock your MAC ID with the router and enable the Firewall so that no-one else can use it.You will need to look up your User Manual to find out how to do these things.If you want a more detailed answer specific to your router, please ask another question specifying which router you use.
