25 Questions

1. The protocol used in IPv6 for many functions - including address autoconfiguration - duplicate address detection - router - neighbor - and prefix discovery - neighbor address resolution - and parameter discovery.

2. Differentiated Services Code Point.

3. Defined in RFC 826 - a protocol used on LANs so that an IP host can discover the MAC address of another device that is using a particular IP address.

4. The router that will receive the group traffic when a multicast router forwards group traffic to another router.

5. Ready To Send.

6. EIGRP (and IGRP) allows for the use of bandwidth - load - delay - MTU - and link reliability; the K values refer to an integer constant that includes these five possible metric components. Only bandwidth and delay are used by default - to minimize re

7. The IP address to which Label Distribution Protocol (LDP) sends LDP Hellos. Also used in IP multicast to send packets to all multicast routers.

8. Layer 2 payload compression.

9. Measured Round-Trip Time.

10. A multicast routing protocol that operates in dense mode and depends on the OSPF unicast routing protocol to perform its multicast functions.

11. Used by a policer to classify packets relative to the traffic contract. These packets are considered to be above the traffic contract in all cases.

12. Modular QoS CLI.

13. In the context of SNMP - the Set command is sent by an SNMP manager - to an agent - requesting that the agent set a single identified variable to the stated value. The main purpose is to allow remote configuration and remote operation - such as shutt

14. Clear To Send.

15. The range 239.0.0.0 through 239.255.255.255 that IANA has assigned for use in private multicast domains.

16. An optional contention-free 802.11 access protocol that requires the access point to poll wireless stations before they are able to send frames. Not commonly implemented.

17. The original MPLS protocol used to advertise the binding (mapping) information about each particular IP prefix and associated label. It is slightly different from LDP - but functionally equivalent. See also LDP.

18. Dynamic Trunking Protocol.

19. 64 bits at the end of an IPv6 global address - used to uniquely identify each host in a subnet.

20. The process of taking routes known through one routing protocol and advertising those routes with another routing protocol.

21. Cisco IOS Embedded Event Manager - a feature that monitors events on a router and reports their results. Principally intended to increase availability - EEM provides flexible - granular detection and alerting functions.

22. Orthogonal frequency division multiplexing.

23. In shaping and policing - the definition of parameters that together imply the allowed rate and bursts.

24. With EIGRP - a timer started when a reliable (to be acknowledged) message is transmitted. For any neighbor(s) failing to respond in its RTO - the RTP protocol causes retransmission. RTO is calculated based on SRTT.

25. The ASN assigned to a confederation sub-AS.
