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
label mappings from LSR C.
Figure 16 Label acceptance 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 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.
