Usage Guideline
This command is used to configure an LSP trigger filter rule. The LSP trigger filter
rules are IP access list rules that it is used to control the IP routes that can be used
to trigger the establishment of an LSP. For example, if there are two routes for
172.18.1.0/24 and 172.18.2.0/24 and if the LSP trigger filter permits 172.18.1.0/24
and denies 172.18.2.0/24, then the switch can only establish an LSP for 172.18.1.0/
24.
