lsp-trigger

Description
Use the lsp-trigger command to configure the LSP establishment triggering policy.
Use the undo lsp-trigger command to restore the default.
By default, only host routes with 32-bit masks can trigger establishment of LDP LSPs.
An IP prefix list affects only static routes and IGP routes.
•
For an LSP to be established, an exactly matching routing entry must exist on the LSR. With loopback
•
addresses using 32-bit masks, only exactly matching host routing entries can trigger LDP to establish
LSPs.
If you specify the vpn-instance vpn-instance-name combination, the command configures an LSP
•
establishment triggering policy for the specified VPN instance. Otherwise, the command configures
an LSP establishment triggering policy for the public network routes.
• For information about IP prefix list, see the Layer 3—IP Routing Configuration Guide.
Syntax
lsp-trigger [ vpn-instance vpn-instance-name ] { all | ip-prefix prefix-name }

Parameters
vpn-instance vpn-instance-name: Specifies a VPN instance by its name, which is a case-sensitive string of
1 to 31 characters.
all: Specifies that all routing entries can trigger establishment of LDP LSPs.
ip-prefix prefix-name: Specifies an IP prefix list to filter routing entries, so that static routes and IGP routes
that denied by the IP prefix list cannot trigger LSP establishment. prefix-name indicates the name of the IP
prefix list, which is a string of 1 to 19 characters.
