3. Configure the LSP
establishment triggering
policy.
lsp-trigger [ vpn-instance
vpn-instance-name ] { all | ip-prefix
prefix-name }
Optional.
By default, only host routes with
32-bit masks can trigger
establishment of LSPs.
If the vpn-instance
vpn-instance-name option is
specified, the command configures
an LSP establishment triggering
policy for the specified VPN.
Otherwise, the command
configures an LSP establishment
triggering policy for the public
network routes.
NOTE:
For an LSP to be established, an exactly matching routing entry must exist on the LSR. For example, on an
LSR, to establish an LSP to a loopback address with a 32-bit mask, there must be an exactly matchin
hos
routing entry on the LSR.

With the label re-advertisement function enabled, an LSR periodically looks for FECs not assigned with
labels, assigns labels to them if any, and advertises the label-FEC bindings. You can set the label
re-advertisement interval as needed.
