"When you decide to become CCIE, you are already CCIE." And "Every CCIE is a story." This is my first CCIE routing and switching direction. Two sentences harvested in the course. Today, after so many years, I want to add a sentence "CCIE is just a starting point." To friends who are already CCIEed.

If I am not qualified for multiple CCIEs, I am afraid you will not visit me now? Someone can have the opportunity to be the first person to reach a certain milestone. This situation is not always there. It seems that I am very proud of being qualified for multiple CCIEs. At the beginning, I wanted to qualify for CCIE just to become a senior in the online world and to make my work more secure. I think that no matter how bad the situation is, Cisco will probably not fire employees who are qualified for CCIE, but if Cisco really dismisses a CCIE-qualified employee, then looking for a job for CCIE-qualified people. Relatively easy. I don't want to talk about finding a job. Today's knowledge is power. As a master engineer, the more I master the knowledge, the better I can provide better sales services for my account managers and clients.

Q1:Which material is most helpful
Q2:which packets can help you find the cause
Customer just setup a IPv6 Network, with HSRPv6 on R1 & R2. After setting up, all hosts lose connection.
What would you recommend to your L1 Engineer as a Quick Fix?
CE1 key configuration
standby 1 priority 200
standby 1 preempt
ipv6 nd router-preference low
CE2 key configuration
standby 1 preempt
ipv6 nd router-preference high
I think it is a rouge device because I don't see any problems with the HSRPv6 config. PCs are configured with "ipv6 enable", "ipv6 autoconfig"
The R1 have a "ipv6 nd-preference high" and R2 have "low" if I'm not wrong.
How fast fix the problem?
¡ Shutdown the link between CE2 and PE2.
¡ Shutdown the link between CE1 and PE1.
¡ Configure CE1 with highest HSRPv6 Priority.
¡ Configure CE2 with highest HSRPv6 pirority.
¡ Configure CE2 with low HSRPv6 priority.
¡ Shutdown CE1 interface e0/0.
¡ Shutdown PE2 interface e0/0.
¡ Disable fast-switching on CE's LAN.
¡ Enable fast-switching on CE's LAN.
¡ Change HSRPv1 to HSRPv2 version
