What does a nonzero forwarding address indicate in a type-5 LSA? A. It indicates that this link-state ID is eligible for ECMP. B. It indicates that this router should have an OSPF neighbor relationship with the forwardingaddress before using this link-state ID. C. It indicates that the receiving router must check that the next hop is reachable in its routingtable before using this link-state ID. D. It indicates that traffic can be directly routed to this next hop in shared segment scenarioswhere the external route source is directly connected. Answer: DExplanation: The value of the forwarding address specified by the autonomous system boundary router (ASBR)can be either 0.0.0.0 or non-zero. The 0.0.0.0 address indicates that the originating router (theASBR) is the next hop. The forwarding address is determined by these conditions: ASBR's next hop interface address falls under the network range specified in the router ospfcommand ReferencE. - 10.html Cisco 400-101 Exam "Pass Any Exam.

QUESTION NO: 242 Which type of EIGRP routes are summarized by the auto-summary command? Router Three is injecting external routes to 192.1.2.0/26 and 192.1.2.64/26 into EIGRP using theredistribute connected command, as shown in the configurations below. Router Threeinterface Ethernet0 ip address 192.1.2.1 255.255.255.192 ! interface Ethernet1 ip address 192.1.2.65 255.255.255.192 ! interface Ethernet2 ip address 10.1.2.1 255.255.255.0 !router eigrp 2000 redistribute connected network 10.0.0.0 default-metric 10000 1 255 1 1500 With this configuration on Router Three, the routing table on Router One shows: Cisco 400-101 Exam "Pass Any Exam.

However, if you reconfigure the link between Routers Two and Three to192.1.2.128/26, and add network statements for this network on Routers Two and Three, the192.1.2.0/24 auto-summary is then generated on Router Two.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
