The IPv6 Management route has lower metric than the static IPv6 tmm route. As a result, traffic that matches the default route goes to the mgmt interface.
The incorrect routing table sends the traffic that matches the default route to the mgmt interface.
Create an IPv6 mgmt route and a static IPv6 tmm route on the same BIG-IP system. IPv6 routes from TMM are injected at metric 1024.
None.
The IPv4 and IPv6 management routes now have a metric value of 4096. Default value of static routes are 1 for IPv4 and 1024 for IPv6. This makes static routes (TMM routes) preferred over management routes, which is correct behavior.
