BGP Filters: Distribution and Prefix lists

Share this page:

The main difference between applying the DISTRIBUTE list and the PREFIX list to the BGP neighbor is:

- DISTRIBUTE LIST: You need to define the ACL, and apply it in the form of a Distribution List:

(config)#access-list 1 deny 172.12.25.0 0.0.0.255
(config-router)#neighbor 5.5.5.5 distribute-list 1 in

- PREFIX LIST: You define the PREFIX list, and apply the same prefix list to the BGP neighbor

(config-router)#neighbor 5.5.5.5 prefix-list PREF_LIST in
