## AI overview

A BGP lab exercise explains how limiting the number of prefixes accepted from customer routers can reduce the impact of routing misconfigurations, such as redistributing IGP routes into BGP or advertising the entire DFZ routing table.

## Source excerpt

Here's an easy way to stop fat-finger incidents in which an end-user autonomous system redistributes IGP into BGP or advertises the whole DFZ routing table from affecting the entire Internet: limit the number of BGP prefixes your routers accept from your customers. You can practice this nifty feature in the next BGP lab exercise.
