BGP suumry
Use a network statement to advertise the summary address
- Auto-summary: a router summaries its locally-originated BGP networks to their classful boundaries. Also, all reditributed subnets (into BGP, if a router has) will be summarized to their classful boundaries into BGP table.
- Synchronization: If your AS is a transit AS, synchronization prevents a BGP speaker from advertising a route to an EBGP peer until all routers within the speaker’s AS have learned about the route via an IGP.
