Explanation:
what value will OSPF use as its router ID?
Refer to the exhibit.
If the router Cisco returns the given output and has not had its router ID set manually, what value
will OSPF use as its router ID?
How come the answer is C
the loopback with the highest id is 2.2.2.2 not C, DR is 1. highest loopback id 2. highest ip
D (2.2.2.2) is correct:
1. If the router-id rid OSPF subcommand is configured, this value is used as the RID.
2. If any loopback interfaces have an IP address configured, and the interface has an interface status of up, the router picks the highest numeric IP address among these loopback interfaces.
3. The router picks the highest numeric IP address from all other interfaces whose interface status code (first status code) is up. (In other words, an interface in up/down state will be included by OSPF when choosing its router ID.)
You can use a loopback interface to establish a Telnet session, ping the switch, and access the switch through SNMP, SSH, and HTTP (WebAgent). A loopback IP address can be used by routing protocols. For example, you can configure the loopback IP address as the router ID used to identify the switch in an OSPF area
