Meet the instructor and learn a systematic approach to troubleshooting IP surfaces on Cisco devices, covering DHCP, NAT, NTP, and HSRP through hands-on labs and a practice test.
Explore the ip services lab topology with four routers, nat on router two, and dhcp from router three. Verify router two is active in 192.168.15.0/24 and test connectivity to 192.168.30.0/24.
Copy the md5 authentication configuration from router two to router one to fix the hsrp authentication mismatch on ethernet 0/0 and enable preemption with router two's higher priority.
Resolve the nctb clock synchronization on router two by diagnosing MTV status and association details, fixing dhcp/switch issues, and ensuring proper route advertisement to reach router four.
Identify and fix a NAT misconfiguration on router two that blocks connectivity from router one to router four; correct inside/outside interfaces, verify with NAT translations, then restore connectivity.
Explore IP services lab 2 topology in the Cisco troubleshooting labs, using the same base configuration and tickets as lab 1, with the DHCP server moved to router four.
Resolve a duplicate address in two groups by deleting group two on router two, configuring group one to 192.168.12.254, and enabling preemption to make router two the active HSV router.
Troubleshoot MTV time synchronization by correcting the DHCP helper address and interface IPs, enabling reachability between router two and router four, and matching the authentication key.
Troubleshoot connectivity between router one and router four by tracing the path, verifying routing and nat, and correcting the nat access-list to permit 192.168.12.0 with wildcard mask of class C.
*** Part of the full Course: Cisco Troubleshooting Labs For CCNA, CCNP, and CCIE Students (The best seller course in the CCIE Enterprise category Category ) ***
Troubleshooting is an essential and important skill for network engineers. As a network engineer, you have to know not just how to configure network devices, but also how to troubleshoot them. And for troubleshooting to be efficient, it has to be systematic and logical and not by random trial and error attempts.
In this course, I will demonstrate troubleshooting of IP Services on Cisco Devices. You can use this course to learn how to troubleshoot Cisco Routers in real production and to help you to prepare for the CCNP TSHOOT exam and the Troubleshooting section of the CCIE lab exam. If you are already have CCNA level knowledge and/or experience, or you are in the middle of your CCNA studies, then you can use this course as a start for learning advanced troubleshooting.
In this course you will learn how to troubleshoot the following IP services:
DHCP (Dynamic Host Configuration Protocol)
NAT (Network Address Translation)
NTP (Network Time Protocol)
HSRP (Hot Standby Router Protocol )
This course uses multiple explaining ways in addition to videos. At the beginning of the course there is an article for summarized troubleshooting steps that is available for download as a PDF and which I recommend to be read before watching the videos. And for each lab, initial configuration will be available for download in order for students to practice the labs and challenge themselves if they can solve the tickets before watching the videos or even after. In addition, there will be a practice test for the student to check what he has learned. Some tickets have multiple possible solutions. Therefore, restrictions have been set so that there should be only one valid solution.
Let us start the course together and begin the troubleshooting journey. Happy troubleshooting !
