all: Specifies all FECs, that is, all static routes and IGP routes. 

prefix-name: Name of the IP address prefix list, a string of 1 to 19 characters. 

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 loopback addresses with 32-bit masks can trigger LDP to establish LSPs. 

Note that: 

z 

With the all keyword specified in the lsp-trigger command, all static and IGP routes can trigger 

LDP to establish LSPs. 

z 

With the ip-prefix  prefix-name keyword and argument combination specified in the lsp-trigger 

command, only static and IGP routes permitted by the IP address prefix list can trigger LDP to 

establish LSPs. 

z 

An IP address prefix list affects only static routes and IGP routes. 

z 

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.

For information about IP address prefix list, refer to Routing Policy Configuration in the IP Routing 

Volume. 

# Configure LDP to allow all static and IGP routes to trigger LSP establishment.
