By default, only loopback addresses with 32-bit masks can trigger LDP to establish
LSPs.
Note that:
With the all keyword specified in the lsp-trigger command, all static and IGP
■
routes can trigger LDP to establish LSPs.
Using ip-prefix prefix-name keyword and argument combination in the
■
lsp-trigger command, only IGP routes surviving the IGP route filtering based
on an IP address prefix list can trigger LDP to establish LSPs.
For an LSP to be established, an exactly matched routing entry must exist on
■
the LSR. With loopback addresses using 32-bit masks, only exactly matched
host routing entries can trigger LDP to establish LSPs.
An IP address prefix list affects only static routes and IGP routes.
■
For information about IP address prefix list, refer to "IP Addressing
■
Configuration Commands" on page 781.
