Send an ARP broadcast. A will send an ARP broadcast to access the MAC address of the B server, and B has to respond, so A gets the MAC address of B. 2. aggregation layer : the convergence layer of the access point , can provide routing decisions .

Enable RIPng protocol ipv6 router rip xxx (process name) The CCIE routing and switching direction exam is finally over. After half a year of hard work, it passed smoothly. Thanks to my loved ones, my classmates and teachers, and those who support me. Thank you very much! ! ! ! ! , Configuration key 1 (2) The number of CCIE itself is worth The address format is the same as the global unicast address Configuration key 1 When the candidates who followed the exchange of TS1's MPLS *** solution, the language was too rigid. From PC104 to SW3 to R9~ all the way up to check the default route, RT, neighbors, R7 routing and NAT, almost no idea. There are several other institutions in the 4 points that are directly linked to the candidates. =========================================================== ================ RIPng test Set the command buffer size Router rip In particular, the device adds a link layer check based on the strict URPF check. After confirming that there is a route to the source address and the outbound interface,ccie lab exam fee, the device adds an ARP entry to ensure that the packet is received. The source MAC address is the same as the MAC address in the ARP entry. The link layer check function is more suitable for deployment when a single Layer 3 Ethernet interface is used to access a large number of PC users.

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
