R1 is configured with the default configuration of OSPF.
From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?
| A. |
192.168.0.1 | |
| B. |
172.16.1.1 | |
| C. |
172.16.2.1 | |
| D. |
172.16.2.225 |
The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:
- The highest IP address assigned to a loopback (logical) interface.
- If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen.
- The router ID can be manually assigned
In this case, because a loopback interface is not configured so the highest active IP address 192.168.0.1 is chosen as the router ID.
