A router has been configured with the following line "ip address 172.16.10.2 255.255.255.0 secondary" in interface configuration mode. What does this command do?
Adds an IP address to the interface for load balancing of traffic.
Adds 172.16.10.2 as a second IP address on the interface.
Adds the IP address 172.16.10.2 to the interface, which is automatically selected as a Router-ID.
Add an IP address to the interface which will be used when routing traffic out to host 172.16.10.2.
The keyword "Secondary", at the end of the "ip address" command allows a second IP address to be configured under the same interface. A routing protocol such as OSPF will select the primary IP address as the RID instead of the secondary IP.
