RS Written Test
The R& S written test is a 100 multiple-choice question closed-book exam. You have two hours to complete the test. You can take the test at Prometric or VUE testing centers. Prometric's web site is at www.2test.com and VUE's web site is at www.vue.com cisco. The test costs 300 US. Pass marks are set using statistical analysis usually varying between 65 and 75 percent for a passing score. The more testers that pass the test, the higher the passing score if the number of passing testers...
Configuration Register
The configuration register is a 16-bit virtual register that specifies boot sequence and break parameters and sets the console baud rate. The register is usually represented in hexadecimal. Figure 3-1 shows one of the common values for the configuration register, 0x2102. Another common value is 0x0101. The significance of each bit in the configuration register is described in this section. You can change the configuration register by using the global configuration command config-register. The...
BGP Prefix Filter
BGP prefix lists filter routes inbound or outbound to a neighbor. The list filters the routes that are sent to, or received from, a BGP neighbor. When the route in an update matches an entry in the prefix list, the router does not need to continue trying to match entries in the list. The result is that if there are multiple entries in the list that will match a given route, the entries in the top of the list, which are the entries with the lowest sequence numbers, will be used. An implicit deny...
Scenario
This scenario reviews your knowledge of DLSw. Knowledge of DLSw configuration and RIF construct in DLSw environment is essential for the CCIE written test. Use Figure 4-35 to answer the following questions. 1 What is the RIF from Host A to Host C 2 What is the RIF from Host A to Host B 3 What is the correct configuration of Router A interface loopback 0 ip address 1.1.1.1 255.255.255.255 dlsw local-peer peer-id 1.1.1.1 dlsw remote-peer 0 tcp 2.2.2.2 dlsw remote-peer 0 tcp 3.3.3.3 interface...
Q A
The Q & A questions are more difficult than what you can expect on the actual exam. The questions do not attempt to cover more breadth or depth than the exam however, they are designed to make sure that you retain the material. Rather than allowing you to derive the answer from clues hidden inside the question itself, these questions challenge your understanding and recall of the subject. Questions from the Do I Know This Already quiz are repeated here to ensure that you have mastered the...
Answers to Q A Section
1 If the configuration register is set to 0x2101, where is the IOS image booted from The least significant number of the configuration register (ox2101) determines which image is loaded. If set to 0x1 (0001 binary), the router boots the ROM image. 2 Which command copies the IOS image file from a UNIX server into flash d. copy tftp startup-config Answer b 3 Which switch command's output is similar to the output of the router show ip interface brief command The switch show port status command...
LAN Security
This section covers bridging access lists, IEEE 802.1x port-based access protocol, and private VLANs. Cisco provides two types of bridging access lists. The first is based on MAC addresses, the second on Ethernet types. The access list numbers for MAC address filters are from 700 to 799. The access list numbers for ethertype filters are from 200 to 299. MAC addresses can be filtered at the interface level, inbound or outbound. You use the input-access-list or output-access-list keywords in the...
Interim Local Management Interface ILMI
ILMI is an ATM Forum standard that specifies the use of mechanisms and formats previously defined by the Simple Network Management Protocol (SNMP). Although it is based on SNMP, ILMI communication uses a transport other than IP that traverses only the physical ATM link. ILMI messages are carried over a well-known PVC. The ATM Forum PVC for ILMI uses the VCI 16. Configuration, status, and control information about physical and ATM-layer parameters of the ATM interface Interface attributes...

HSRP Configuration
Figure 6-13 shows an example for the use of HSRP. Host A is configured with a default gateway of 192.168.1.1. Router A and Router B are configured for HSRP. Router A is configured with a higher priority than Router B, and the default priority is 100. The default timers are hellotime 3 seconds and holdtime 10 seconds. Authentication is used for the HSRP group, and the password is secret. The routers are also configured to preempt, so if Router A fails or the serial interface in Router A fails,...
EIGRP Components
The characteristics of EIGRP are as follows Neighbor discovery and recovery Reliable Transport Protocol (RTP) EIGRP uses different modules that independently support IP, Internetwork Packet Exchange (IPX), and AppleTalk routable protocols. These modules are the logical interface between DUAL and routing protocols, such as IPX RIP, AppleTalk Routing Table Maintenance Protocol (RTMP), and IGRP. The EIGRP module sends and receives packets but passes received information to DUAL, which makes...
BGP show Commands
This section briefly reviews some show commands that you can use with BGP. For the CCIE written exam, know how to read the fields in the output of these commands. The first command is show ip bgp neighbors, as shown in Example 9-17. Use this command to check if a TCP connection has been established with the neighbor. The BGP neighbor is the IP address of the peer. The remote AS number is provided. The remote RID is the BGP RID of the peer. The BGP state is Established. Notifications are the...
