Ideally, you're looking for it to announce a single 195.89.132.128/26
route, correct? It looks like you've set the first assigned address to
195.89.132.129, so it won't happen. Although you're using a natural
subnet boundary, not all subnet rules apply. You can (and indeed must)
use the first and last addresses in the "subnet". You should have:

Command> set assigned 195.89.132.128
Command> set pool 64

This will give you an assigned range of 195.89.132.128 to 195.89.132.191.
If you don't explicitly set the pool size, the PM3 will not announce a /26
network anyway, because at most it will see 61 possible dial-in interfaces
(60 channels plus C0).

You don't need to reboot if you increased the pool size. However, if you
reduce the pool size, or if you change the assigned address, I'm pretty
sure you must reboot.
