Router 1 was just successfully rebooted. Identify the current OSPF router ID for Router 1.
A.
208.149.23.194
B.
220.173.149.10
C.
208.149.23.162
D.
190.172.32.10
Explanation:
To identify the router ID for Routerl, do as follows:
– Step 1 Choose from all the activated interfaces.
– Step 2 Compare the IP addresses of loopback interfaces.
– Step 3 If there are no loopback interfaces, compare the IP addresses of all the physical interfaces.
Configures an OSPF router ID.
Description: Router ID is the tie-breaker for OSPF path selection. The path selection process uses a variety of metrics to select a route. If all other metrics (accessibility, administrative weight, local preference, etc.) are equal, OSPF determines the router ID using the following priority:
1.Use the address configured by the ospf router-id command
2.Use the address of the loopback 0 interface
3.Use the highest IP address of any interface
4.If no interface exists, set the router-ID to 0.0.0.0
5.lf no OSPF router ID is explicitly configured, OSPF computes the router-ID based on the items 2, 3, and 4 and restarts OSPF (if the process is enabled and router-ID has changed).
WARNING The ospf router-id command causes the OSPF process to restart using the new router-ID (if the processes are enabled and router-ID has changed).
Use ospf router-id ip-address command to set the OSPF router ID for the system.
Use the no ospf router-id to configure the OSPF router ID as the default value (address of the loopback 0 interface).
