Creating a Prefix List Without a Sequence Number

To create a filter without a specified sequence number, use the following commands.

1. Create a prefix list and assign it a unique name.
   CONFIGURATION mode
   ip prefix-list prefix-name
2. Create a prefix list filter with a deny or permit action.
   CONFIG-NPREFIXL mode
   {deny | permit} ip-prefix [ge min-prefix-length] [le max-prefix-length]
   The optional parameters are:

   • ge min-prefix-length: is the minimum prefix length to be matched (0 to 32).
   • le max-prefix-length: is the maximum prefix length to be matched (0 to 32).
