Step 3 Run:
lsp-trigger { all | host | ip-prefix ip-prefix-name | none }
The policy of triggering the establishment of LSPs is configured.
l By default, the triggering policy is host, namely, the route of host IP with the 32-bit address
l If the triggering policy is all, all static route entries and IGP route entries trigger to establish
l If the triggering policy is ip-prefix, only the FEC entry filtered in the IP address prefix list
l If the triggering policy is none, the LSP is not established.
