  • Question
  • If routers in a single area are configured with the same priority value, what value does a router use for the OSPF Router ID in the absence of a loopback interface?


  • Options
  • A. The lowest IP address of any physical interface
  • B. The highest IP address of any physical interface
  • C. The lowest IP address of any logical interface
  • D. The highest IP address of any logical interface

  • Correct Answer
  • The highest IP address of any physical interface 

    Explanation
    At the moment of OSPF process startup, the highest IP address on any active interface will be the Router ID (RID) of the router. If you have a loopback interface configured (logical interface), then that will override the interface IP address and become the RID of the router automatically.

    • 2. The Corporate router receives an IP packet with a source IP address of 192.168.214.20 and a destination address of 192.168.22.3. Looking at the output from the Corporate router, what will the router do with this packet?
      Corp#sh ip route
      [output cut]
      R    192.168.215.0 [120/2] via 192.168.20.2, 00:00:23, Serial0/0
      R    192.168.115.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0
      R    192.168.30.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0
      C    192.168.20.0 is directly connected, Serial0/0
      C    192.168.214.0 is directly connected, FastEthernet0/0

    • Options
    • A. The packet will be discarded.
    • B. The packet will be routed out the S0/0 interface.
    • C. The router will broadcast looking for the destination.
    • D. The packet will be routed out the Fa0/0 interface.
