Configuring The Ldp Label Distribution Control Mode; Configuring A Label Advertisement Policy - HP FlexNetwork 10500 Series Configuration Manual

•
Use only IPv4 host routes with a 32-bit mask or IPv6 host routes with a 128-bit mask to
establish LSPs.
By default, LDP uses only IPv4 host routes with a 32-bit mask or IPv6 host routes with a 128-bit mask
to establish LSPs. The other two methods can result in more LSPs than the default policy. To change
the policy, make sure the system resources and bandwidth resources are sufficient.
To configure an LSP generation policy:
Step
1. Enter system view.
2. Enter LDP view or enter
LDP-VPN instance
view.
3. Configure an IPv4 LSP
generation policy.
4. Configure an IPv6 LSP
generation policy.

Configuring a label advertisement policy

A label advertisement policy uses IP prefix lists to control the FEC-label mappings advertised to
peers.
As shown in
B. It advertises label mappings for FECs permitted by IP prefix list C to LSR C.
