The BGP scanner by default runs every 60seconds. It goes through and updates the BGP tables (remove or add routes based on current information).
For filtering on the inbound direction, you can filter based on prefix or ASN. The following example is a bit of an overkill, but it only allows the /23 prefix listed, routes in this /23 originated in the AS listed, and a max of 50 routes to be advertised to this device:
neighbor 22.214.171.124 remote-as 65001
neighbor 126.96.36.199 description [Customer-A]
neighbor 188.8.131.52 prefix-list Customer in
neighbor 184.108.40.206 maximum-prefix 50
neighbor 220.127.116.11 filter-list 32 in
ip prefix-list Customer-In description [Customer-A]
ip prefix-list Customer-In seq 5 permit 10.0.0.0/23
ip as-path access-list 32 permit _65001$
You could always talk to your ISP and take partial routes instead of a full table if you wanted. Hope this helps.
