8.27.1 Route Processing on the BGP router
This section describes the route processing on the BGP router.
Figure 8-10 shows the route processing on the BGP router. BGP routes can be imported from
other protocols or learned from BGP peers. Route summarization can be configured to reduce
the routing table size before routes are selected, advertised, and delivered to the IP routing table.
