Configuring a label acceptance policy
A label acceptance policy uses an IP prefix list to control the label mappings received from a peer.
As shown in Figure 15, LSR A uses an IP prefix list to filter label mappings from LSR B, and it does not filter label mappings from LSR C.

A label advertisement policy on an LSR and a label acceptance policy on its upstream LSR can achieve the same purpose. HP recommends using the label advertisement policy to reduce network load.
You must create an IP prefix list before you configure a label acceptance policy. For information about IP prefix list configuration, see Layer 3—IP Routing Configuration Guide.
