Re: BGP Update announcement Time

BGP routers keep scaning its routing table in every scaning interval, which can be tunable between 5-60 secs using the command bgp scan-time . The new route need not be configured in all routers, just advertise using the network command will do. It may take some time get advertised, can use clear ip bgp * soft to immedately update the table.
