latter’s OSPF domain, the PE router presents itself as an ASBR (Autonomous System BorderRouter), and distributes the route in a type 5 LSA. The DN bit [OSPF-DN] MUST be set in theseLSAs to ensure that they will be ignored by any other PE routers that receive them. Cisco 400-101 Exam "Pass Any Exam. Any Time." - 167

QUESTION NO: 201 Which two statements are true about IS-IS? (Choose two.) A. IS-IS DIS election is nondeterministic. B. IS-IS SPF calculation is performed in three phases. C. IS-IS works over the data link layer, which does not provide for fragmentation and reassembly. D. IS-IS can never be routed beyond the immediate next hop. IS-IS runs directly over layer 2 and hence: - cannot support virtual links unless some explicit tunneling is implemented - packets are kept small so that they don't require hop-by-hop fragmentation - uses ATM/SNAP encapsulation on ATM but there are hacks to make it use VcMux encapsulation - some operating systems that support IP networking have been implemented to differentiate Layer 3 packets in kernel. Such Oss require a lot of kernel modifications to support IS-IS for IP routing. - can never be routed beyond the immediate next hop and hence shielded from IP spoofing and similar Denial of Service attacks ReferencE. QUESTION NO: 202 Which command do you use to connect a dense-mode domain to a sparse-mode multicast domain?

    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.
