Some addresses are unreachable through nlams05. For instance:

Meanwhile, for some other addresses like www.ipv6.org, it works fine:

On the other hand, at the same time, by using nlhaa01, the first unreachable address through nlams05 can be reached:

some addresses unreachable
Some addresses are unreachable through nlams05. For instance:
Tracing route to 2001:da8:200:900e:0:5efe:166.111.64.176 over a maximum of 30 hops
That is an address somewhere in China, most likely even located behind an IVI gateway. Your traceroute does not even work locally.
[..] On the other hand, at the same time, by using nlhaa01, the first unreachable address through nlams05 can be reached:
What exactly is your local routing table and through how many paths are you trying to send packets outbound?
Please read that big orange box.
