15.3(3)S 15.4(1)S 15.4(2)S 15.4(3)S

Description (partial)

Symptom:
Tunnel interface QoS may not work after route distance change.

Conditions:
This happens when there are multiple tunnel interfaces whose traffic is all tunneled to the same physical interfaces, with multiple routes for each tunnel traffic, where route distance determines the physical interface for the tunnel traffic.

With QoS applied to the tunnel interfaces, when the tunnel traffic route distance is changed to select different physical interface, the QoS on that tunnel interface no longer works, after the change.
