why are ip addresses overlapping in packet tracer? 202.101.99.192 overlaps with GigabitEthernet0/1

This is my router! the topology is one router connected to one pc on g0/1, on g0/0 its connected to a switch then connected to a pc. the whole network is 202.101.99.0/24, using VLSM we had to break it down first with 98 usable hosts so I decided for the IP address of the router for g0/0 I want to use 202.101.99.129 255.255.255.128., then I assigned the pc 202.101.99.130, I went to assign the IP address to the g0/0 and its saying theyre over lapping..why is this

For interface g0/1 you're using the network 202.101.99.128 /25. With this, the network address is 202.101.99.128, the usable hosts range from 202.101.99.129-202.101.99.254. Your broadcast address would be 202.101.99.255.

For interface g0/0 you assigned it 202.101.99.161 which is using the 202.101.99.160 /27 network. This overlaps with your previous network. Because as stated above, the 202.101.99.128 /25 network covers the ranges .129-.254.

By looking at the chart below, you can see that your first network takes up all of the addresses in the red box, ranging from .128 - .255 In order to not have overlap, you would have to assign g0/0 one of the network addresses in the green box.

If each network is supposed to have 98 usable hosts, your best option would be to use the 202.101.99.0 /25 and 202.101.99.128 /25 networks
