I just now discovered this:
google.com: 2a00:1450:400e:807::200e
That address works fine. But then I changed that one bit in the address: 2a00:1450:400e:8807::200e and voila, the router drops the packet.
Now I am stumbled. What could the 49th bit in the destination IPv6 address field in a packet mean to the router, that would make it drop the packet?
Are you sure it is dropped? Can you see some drop counter increase? Have you observed nothing coming out from any port? My guess is bad memory, and that bit is statically set or statically unset and cannot be changed. Might cause CRC error, IP checksum error or just mangled packet coming out of the router -- ++ytti
