I'm managing one BGP router, under the router I'm trying to announce the following IP prefix:161.117.25.0/24. But the problem is that some of the IP addresses were borrowed by other AS(Autonomous System), for example the IP address 161.117.25.100 and 161.117.25.200 were borrowed by other AS. So how should I announce the remaining IP addresses please.

Following questions please:

1, Can I announce `161.117.25.0/30`?

2, Is it possible that two Autonomous Systems announce or have the same ip prefix?

1, If I forcedly announce `161.117.25.0/24`, what will be happened?
 other AS's ip `161.117.25.100` would not be reached anymore?
