Routing & Switching
The video demonstrates IPv6 HSRP configuration on Cisco router. We will show how HSRP is integrated with IPv6 Router Advertisement message to provide first hop redundancy to end-hosts. HSRPv6 will be operationally compared to the IPv6 Default Router Preference method and any distinctions between the two will be made. We will use a router and Windows 7 computer as our test end devices.

Awesome video
I tried playing around with your setup and when i lower default preference to low on active it still forwards the traffic , is that how it should work ?
Awesome video
do you have preemption on the other side? If not, try that and see if it make a difference
Actually i think i miss
Actually i think i miss configured something , so i did exact scenario as you have but on on R1 nd priority low (preemt is on R1) and i cant ping the destination. i think this is a right result right ?
Host will choose medium priority R2 with virtual ip but HSRP will forward packet to R1 since it is a Active Router. am i correct ?
Router with higher priority
Router with higher priority is always active, owns the virtual IP, responds to ND and forward packets. Assuming R1 is active, once its priority falls below R2, R2 will become active. Preemption only comes in when R1 regains its priority and you want it to take over the active role.
