RE: suppress-map vs advertise-map

Hi Modi,

When you make a supernet with aggregate-address without summary-only keyword, you can "suppress" some specific networks using suppress-map, so you would announce the supernet and some specific nets.
For example, we have the bgp networks 10.0.1.0/24, 10.0.2.0/24 and 10.0.3.0/24. With aggregate-address we make a supernet 10.0.0.0/22, so we would announce this supernet and also the specific nets.
If we use a suppress-map, we could make not to announce the network 10.0.2.0/24, so we would announce the supernet and also 10.0.1.0/24 and 10.0.3.0/24

With advertise-map you can make a conditional advertise, let's say, if I have this network on my bgp table, then advertise this other network.
