When URPF check is enabled on a dot1q VLAN tag termination sub-interface, only URPF in loose mode takes effect.

Even if the strict mode is configured, the loose mode takes effect.

When you configure the strict urpf on the interface, the L3-loop-detect function will fail.

In scenarios with sub-interfaces for dot1q VLAN tag termination or flexible access sub-interfaces, if unicast RPF (uRPF) check in strict mode is configured in the CPU defend policy view or interface view, the system automatically switches to uRPF check in loose mode.
