The static-cr-lsp rpf disable command disables a device from checking inbound interfaces of static CR-LSPs.
The undo static-cr-lsp rpf disable command enables a device to check inbound interfaces of static CR-LSPs.
By default, this function is enabled.
Usage Scenario
The check for static CR-LSPs' inbound interfaces enables a device to check whether the inbound interface of labeled packets is the same as the configured inbound interface of a static CR-LSP. If an inbound interface inconsistency occurs, the device discards the packets and generates an alarm.
Precautions
The check for static CR-LSPs' inbound interfaces can only take effect on Ethernet sub-interfaces for dot1q Eth-Trunk main interfaces, Eth-Trunk sub-interfaces for dot1q LAN tag termination, and Layer 3 Ethernet main interfaces.
