bgp ip-access-list
BGP peers and route maps can reference a single IP based ACL
(access control list). Apply IP ACLs to both inbound and outbound route
updates. When applied to a BGP enabled router, every route update is passed through the ACL.
Each ACL contains deny and permit entries that are applied sequentially, in the order they
appear within the list. When a route matches an entry, the decision to permit or deny the
route is applied. Once a match is made the remaining entries in the ACL are not
processed.
BGP IP ACLs are used as match criteria in the following contexts:
- BGP neighbor. For more information, see use.
- BGP route-map context. For more information, see match.
To navigate to the BGP IP ACL configuration instance, use the following
command:
<DEVICE>(config)#bgp ip-access-list <IP-ACL-NAME>
<DEVICE>(config-bgp-ip-access-list-<IP-ACL-NAME>)#?
