Then you can directly enter MPLS view after using the mplscommand in system view.Use the mpls command in VLAN interface view to enable MPLS on the VLANinterface.Table 36-2 Enter MPLS viewOperation CommandEnable MPLS globally and enter MPLS view (system view)Enable MPLS on a VLAN interface (VLAN interface view) mplsDisable MPLS globally or on a VLAN interface (system or VLANinterface view) undo mplsBy default, MPLS is not enabled.36.2.3 Configuring the Topology-Driven LSP Setup PolicyIt refers to specifying filtering policy as all or ip-prefix.Perform the following configuration in MPLS view.Table 36-3 Configure the topology-driven LSP setup policyOperation CommandConfigure the topology-Driven LSPsetup policy lsp-trigger { all | ip-prefix ip-prefix }Use the default value, which only allows32-bit IP to trigger ISP.undo lsp-trigger { all | ip-prefixip-prefix }36.2.4 Configuring Static LSPYou can manually set an LSR to be a node along an LSP, and place a limit on the trafficover the LSP. Depending on the position in an MPLS domain, an LSR along an LSP can
