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:

host1(config)#ip prefix-tree boston42 permit 10.10.2.0/24

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