guys just a quick one.........suppose there are three sites A,B,c all are connected via bgp and have seprate AS's.
now if site A is advertising site B network suppose 192.168.1.0/24. so site b is connted via BGP with c as well the route will be in site B table.....so that specific route would be advertise to site C by B by default as they are connected as well via BGP(keeping in mind that site c doesnt need to get this route)? if yes why if not why??? is this why we use prefix-list?? ic ant get my head around it. Thanks guys in advance
