Global dynamic bandwidth pre-verification enables a device to check dynamic bandwidth usage before a static CR-LSP, or a static bidirectional co-routed LSP is established.
When dynamic services or both static and dynamic services are configured, a device only checks static bandwidth usage when a static CR-LSP or a static bidirectional co-routed LSP is configured. The configuration is successful even if the interface bandwidth is insufficient, and the interface status is Down. To percent such an issue, global dynamic bandwidth pre-verification can be configured. With this function enable, the device can prompt a message indicating that the configuration fails in the preceding situation.
