+ | ===== The Route Maps ===== | ||
+ | While you can just use prefix lists with BGP to control routes imported and exported, route maps give you much more flexibility and control, and can even include AS path matching. | ||
+ | < | ||
+ | route-map BGP-ISPv6-From { | ||
+ | rule 10 { | ||
+ | action permit | ||
+ | match { | ||
+ | ipv6 { | ||
+ | address { | ||
+ | prefix-list BGP-ISPv6-From | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | route-map BGP-ISPv6-To { | ||
+ | rule 10 { | ||
+ | action permit | ||
+ | match { | ||
+ | ipv6 { | ||
+ | address { | ||
+ | prefix-list BGP-ISPv6-To | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | route-map BGP-ISP-From { | ||
+ | rule 10 { | ||
+ | action permit | ||
+ | match { | ||
+ | ip { | ||
+ | address { | ||
+ | prefix-list BGP-ISP-From | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | route-map BGP-ISP-To { | ||
+ | rule 10 { | ||
+ | action permit | ||
+ | match { | ||
+ | ip { | ||
+ | address { | ||
+ | prefix-list BGP-ISP-To | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||
+ | } | ||

+ | Like the prefix lists, -To and -From are your specific directions in and out (import and export). |
