Explanation:

The QoS for VPNs feature, which is enabled by the qos pre-classify command, is restricted to tunnel and virtual template interfaces, and crypto map configuration submodes.
For generic routing encapsulation(GRE) and IP in IP(IPIP) tunnel protocols, the qos pre-classify command is applied on the tunnel interface, making QoS for VPNs a configuration option on a per-tunnel basis.
For Layer 2 Forwarding(L2F) and Layer 2 Tunneling Protocol(L2TP) protocols, the qos pre-classify command is applied on the virtual template interface. L2TP clients belonging to identical virtual private dial-up network (VPDN) groups inherit the preclassification setting. The qos pre-classify command can be configured on a per-VPDN tunnel basis. For IPSec tunnels, the qos pre-classify command is applied on the crypto map, allowing configuration on a per-tunnel basis. QoS features on the physical interface carrying the crypto map are able to classify packets before encryption. To configure the QoS for VPNs feature on a tunnel or virtual interface basis, use the following commands beginning in global interface mode:

To configure the QoS for VPNs feature on the crypto map configuration basis, use the following commands beginning in global configuration mode:
