    Creating or Configuring an IP Prefix Tree for Best Route Filtering

    You can use the ip prefix-tree command to create a prefix tree for best route filtering. The ip prefix-tree command specifies a tree entry—a deny or permit clause for a network address. The prefix tree name can be up to 32 characters long.

    To create a prefix tree for best route filtering:

    • Issue the ip prefix-tree command in Global Configuration mode.
    host1(config)#ip prefix-tree boston42 permit

    Use the no version to remove the specified prefix tree or the specified tree entry.
