I've never had to use BGP (mostly work on LAN stuff in medium businesses) but I am curious about it.
Suppose a client has 2 internet connections from 2 isp's. Each isp assigns a /28 block of addresses.
Assuming the isp's let the client pair with them (I think that's the term in this case) via BGP would the client advertise all public ip's to both isp's?
If this is the case does that mean that if one of the isp's assigns an ip of 1.2.3.4 (lets just say it's TWC) and it goes down could that ip still be reachable through the other isp since it also has the route via BGP of the other WAN link that is still up?
