  • ( Such as OSPF and BGP4) supported by a method based on ignoring TP concept of address classes, allowing route summarization and routers can be combined to minimize the need for routing the main transmit routing information in the router VLSM . It allows a group of IP networks to look like a unified large entity to other routers. In CIDR , IP addresses and their subnet masks are written There are multiple links on the same network, and STP will shut down - ports to block network loops. =========================================================== =============== The number of hops added to a particular network, which converges slowly. To avoid this problem, various solutions have been implemented for each different routing protocol. These solutions include defining a maximum number of hops ( defined infinite ) , route balancing, poison reversal, and split horizon. 2. Different VLANs cannot communicate directly . Interface fa0/24 =========================================================== =========== 1. Port-based implementation , static VLAN 2. Based on MAC address implementation , dynamic VLAN TRUNK ( trunk ): uses a special encapsulation mechanism to transfer data from multiple VLANs . =========================================================== =============== FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. Ripv2 is a multicast method to advertise the network , multicast address : router rip =========================================================== =============== B (config-if) #ip nat inside configured S0 interface inside the network Physical layer : An ATM network configured with a ring of LAN . Multiple ELANs can exist simultaneously on one ATM network and form a LAN Emulation Client (LEC) , a LAN emulation server, a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS) .

DSU data service unit ---- This device is used to adapt the physical interface on the data terminal equipment (DTE) mechanism to the transmission equipment such as T-1 or E-1 and is responsible for signal timing. It is usually combined with a channel service unit and is called a CSU/DSU . See CSU . Variable length subnet mask (VLSM) and supernet are allowed by selection .

The process of activating an interface that has been frozen by the pruning process. It is initiated by an IGMP member report sent to the router . DHCP Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol) ----- DHCP is The process of packaging or inclusion. In the OSI reference model, when data flows down the protocol stack, each layer encapsulates its next layer. There is traffic successfully reaching the destination. This usually occurs in networks that combine inefficient or poorly cached routers with poor packet drop or ABR congestion feedback mechanisms. Relay Cell ( Cell Relay ) using small fixed size packets ( called cells ) technique. Their solid data frame ( data frame ) the OSI protocol data unit package on the reference model data link layer. From the network layer R14(config)#dialer-list 9 protocol ip list 1 Dynamic NAT configuration Use more than one metric to find the best path to a remote network. By default, both IGRP and EIGRP use the bandwidth and latency of the line. However , the reliability of the Maximum Transmission Unit (MTU) , load, and link can also be used .

CCIE Security LAB 

Exam Description

The CCIE Lab exam is an eight-hour, hands-on exam which requires you to configure and troubleshoot a series of complex networks to given specifications. Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE lab exam.

DIAG:1 hour

the act or process of identifying the root cause

TS: The Troubleshooting module is 2 hours. If desired, candidates can extent the Troubleshooting module's time by borrowing up to 30 min from the Configuration module. Note, the total Configuration module time will be reduced by the extra time spend in the Troubleshooting module (if any, up to 30 min). If candidates finish the Troubleshooting module early, the unused Troubleshooting module’s time will be added to the Configuration module’s time, ensuring a total lab exam time of 8 hours. 


The Configuration module provides a setup very close to an actual production network having various security components providing various layers of security at different points in the network. Though the major part of the module is based on virtual instances of the Cisco security appliances, the candidate may be asked to work with physical devices as well. At the beginning of the module, the candidate has full visibility of the entire module. A candidate can choose to work in the sequence in which the items are presented or can resolve items in whatever order seems preferable and logical.
