Will BGP advertise both networks - 220.127.116.11/20 and 18.104.22.168/32 ?
If so, when I change the 'network 22.214.171.124 mask 255.255.240.0' statement to 'aggregate-address 126.96.36.199 mask 255.255.240.0', and do a clear bgp soft out, will I experience an outage for that network?
Thanks for the response! Sorry for the boundry error - I was just changing the real IP addresses and didn't think to check that.
To get the 188.8.131.52/32 route into BGP, can I add: 'ip route 184.108.40.206 255.255.255.255 Null0' on the same router in addition to the previous commands? The specific route is not currently in the RIB - just the supernet is.
This host is a VPN head-end router. We have two Internet providers and I want to force all of the remote VPN users to user provider B and not "load balance" between providers. So these commands would be added to our BGP router that connects to provider B's circuit.
Adding a static route to null0 for the /32 will result in traffic to this prefix to be dropped as no more specific route will be found in the RIB obviously. That is probably not what you want.
If you want to force traffic to flow via provider B, you could send a more specific route (prefix length longer than 20) via provider B without going all the way down to a /32. The idea when using a route to null0 is to make sure that you have more specific routing entries in the RIB so you won't blackhole the incoming traffic.

Ok, so a couple of options come to mind. The first: 'ip route 220.127.116.11 255.255.255.255 GigabitEthernet 0/1' or the second: 'ip route 18.104.22.168 255.255.255.254 GigabitEthernet 0/1' which would include .203 which is ok with me it that's how it has to be to work.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
