Configuring PHP
Follow these guidelines when you configure PHP:
• When specifying the type of label for an egress to distribute to a penultimate hop, check whether
the penultimate hop supports PHP. If the penultimate hop supports PHP, you can configure the
egress to distribute an explicit null or implicit null label to the penultimate hop. If the penultimate hop
does not support PHP, you must configure the egress to distribute a normal label.
• The device supports PHP when it operates as a penultimate hop.
• For LDP sessions that already exist before the label advertise command is configured, you must reset
the LDP sessions by using the reset mpls ldp command for the PHP configuration to take effect.

the penultimate hop.
label advertise { explicit-null |
implicit-null | non-null }
Optional.
By default, an egress distributes to
the penultimate hop an implicit null
label.
Configuring the policy for triggering LSP establishment
You can configure an LSP triggering policy on an LSR, so only routes matching the policy can trigger
establishment of LSPs, reducing the number of LSPs to be established on the LSR and avoiding instability
of the LSR caused by excessive LSPs.
An LSR supports the following types of LSP triggering policies:
• Allowing all routing entries to trigger establishment of LSPs.
• Filtering routing entries by an IP prefix list, so static and IGP routes denied by the IP prefix list do not
trigger LSP establishment. To use this policy, first create the IP prefix list. For information about IP
prefix list configuration, see Layer 3—IP Routing Configuration Guide.
To configure the policy for triggering LSP establishment:
