CCIE Lab exam--A Successful engineer's Feedback.

As l had got the ccie lab certification, I wanted to write some feedback to help someone who is willing to take the exam.

1.personal suggestion

1. Don't rely on the proficiency of the keyboard, because you can't predict how disgusting the keyboard is, and use the TXT to copy and paste;

2. Familiar with some key points in each version to watch videos and knock more. The more you frustrate, the more you will not give up, and the days of preparing for the test are really horrible. When you experience this, you will think that everything you have paid before is very fulfilling.

Personal experience

I have been self-study before, summed up the experience in actual combat, and explored the expansion of knowledge. Later I discovered that this is not the way. Without systematic learning, knowledge is too narrow, and I simply reported YES AB. Because I have several friends who are PASS PASS at one time, and I hear that the teacher lectures very well! From the registration in December of 17 years, after the registration, I started from CCNA, CCNP, CCIE and then to the preparation stage. This journey is really tough. There is no rest day, and everything is irrelevant to work. In the middle, I changed jobs for some reason. I am even more at a loss, think about it, have taken this step, go all the way to the end, insist on knocking the version 4-5 hours every night, and finally won the victory!

Looking back, the time passed quickly, and a blink of an eye was over the year! Finally, I wish the students of the training camp to cheer! Win your own CCIE number.

TS1+ADDR

Q1 (DHCP)

In one error, an ACL is applied to the vlan12 interface of SW2, which only matches one host address.

Q2 (PPP)

Two errors: 1- There is no announcement of the address of the S4/0 interface on R12; 2- There is no PPP configuration on S4/0 of R17.

Q3 (OSPF)

An error occurred and the COST was modified on R22.

Q4 (EIGRP)

In one error, there is no interface for E1/0 on R11.

Q5 (IPV6)

The server-side address is not declared on the R25.

Q6 (BGP)

The above picture shows the neighbor relationship of VPNV4 between exams, using the form of PEER-GROUP.

1. Perform the load on the R12IPV4 address cluster (maximum-paths 2). Enable MPLS on the interfaces of R2 and R1 and establish LDP neighbors with R1.

2. The VPNV4 neighbor relationship is not established between R5 and R6. R6 needs to be activated under the address cluster.

3. On R5, the policy route is made to the OUT direction of the IBGP neighbor, and all the interfaces are matched. The next command is given to the interface address of R4 and needs to be deleted.

Q7 (DMVPN)

The third phase is started on R15, and an ACL is matched under the S1/0 interface of R14. There are no messages matching the ESP.

Q8 (MPLS-NAT)

Two errors: 1-SW3's SVI interface announces the establishment of an OSPF neighbor; 2-Redistributes OSPF to BGP at R9.

Q9 (NAT over DMVPN)

The tunnel port mask of R24 is incorrect.

Q10 (NAT)

The ACL of R23 matches only one host address, and the entire C address segment is re-matched. I have not made a phenomenon here. The IP address can be obtained on the NAS device. The gateway is normal, that is, the ping fails the gateway, and the ping fails. .cciecloud.net (the domain name has changed here), after checking all the above phenomena from beginning to end, it is still not feasible to check this question, I will not directly submit the volume.

D2+

Open discovery is D2, all device configuration and log navigation pane will be listed on the left side of the page.

1: First check the configuration of CE1 and CE2, which is basically similar to the PDF document.

2: View the log information of the client and find that the gateway points to FE80::666

3: Use the capture file ICMPV6.Type==134 to filter out the first package is FE80::1 The fifth package is FE80: 666, the serial number is 227

First question: Improve the priority of CE2

Second question: High preference gateway information is sent out CE2

Third question: 227

Multicast this question to view the log information of the device: you can judge that R2 has no return packet, you can directly select it.

About pre-configuration:

1. The IBGP neighbor relationship needs to be established between R50-R52. The pre-configuration of R55-R57 and SW10 is not allowed.

2. The EIGRP pre-match between R50-R54 is not named, and the deletion is changed to named;

3. SW1 and SW2 are pre-configured to use network under the OSPF process, but I see that the requirements clearly indicate that the AS65002 cannot be networked. Later, I deleted the pre-configured SW1 and SW2 re-interfaces.

4. On the interface between R1 and each router in the AS65001 area, the OSPF priority is 255 and the R2 configuration is 254. However, I do not require DR or BDR.

About the phenomenon map

The addresses of SW1 and SW2 to tracert R101 (the address of R101 is 10.2.100.100) are loaded, and the rest is the same as the rack.
