Why Does the Switch Allocate MPLS Labels Only to Routes with 32-Bit Masks?

After MPLS LDP is enabled, LSPs are set up automatically, leading to a waste of resources. To prevent resource waste, the system triggers LSP setup according to host IP routes (excluding direct routes) with 32-bit masks by default.

You can also run the lsp-trigger { all | host | ip-prefix ip-prefix-name | none } command to modify an LSP setup triggering policy based on actual needs.
