Chapter 1 COMMANDS FOR ROUTING POLICY

1.1 ip prefix-list description

 Command: ip prefix-list <list_name> description <description>

 no ip prefix-list <list_name> description

 Function: Configure the description of the prefix-list. The “no ip prefix-list <list_name>

description” command deletes the description contents.

 Parameter: <list _name> is the name of the prefix-list; <description> is the description

contents.

 Default: None.

 Command Mode: Global Mode

 Usage Guide: This command can be used for explaining and describing a prefix-list, e.g.

the application and attention matters of the prefix-list.

 Example:

 Switch#config terminal

 Switch(config)#ip prefix-list 3 description This list is used by BGP

1.2 ip prefix-list seq

 Command: ip prefix-list <list_name> [seq <sequence_number>] <deny | permit> < any

| ip_addr/mask_length [ge <min_prefix_len>] [le <max_prefix_len>]>

 no ip prefix-list <list_name> [seq <sequence_number>] [<deny |

permit> < any | ip_addr/mask_length [ge <min_prefix_len>] [le

<max_prefix_len>]>]

 Function: Configure the prefix-list. The “no ip prefix-list <list_name> [seq

<sequence_number>] [<deny | permit> < any | ip_addr/mask_length [ge
