Configuring A Label Acceptance Policy - HP 10500 Series Configuration Manual

Figure 20 Label advertisement control diagram
A label advertisement policy on an LSR and a label acceptance policy on its upstream LSR can achieve
the same purpose. HP recommends that you use label advertisement policies to reduce network load if
downstream LSRs support label advertisement control.
Before you configure an LDP label advertisement policy, create an IP prefix list. For information about IP
prefix list configuration, see Layer 3—IP Routing Configuration Guide.
To configure a label advertisement policy:
Step
1. Enter system view.
2. Enter LDP view or enter
LDP-VPN instance view.
3. Configure a label
advertisement policy.

Configuring a label acceptance policy

A label acceptance policy uses an IP prefix list to control the label mappings received from a peer.
