We currently have a /25 network. We’re getting a tenant in who’ll be sharing our connection, and we thought we’d split the /25 and share it.
Currently things look like this (IP subnet changed for the example):
With a configured outside route of 18.104.22.168
ISP – Switch – R1 22.214.171.124/25
What I’m aiming to achieve:
ISP Router– Switch – R1 126.96.36.199/26
Would this be possible without having the ISP to make any changes on their managed router?
Any help / clarification, appreciated.
Actually, you can put r1 in a /26, but you're going to have to put r2 in a /25 in order to reach .129.
