I am currently redisgning a multi hop wan backbone that links a number of offices and i thought i had the design but after a previous question it has opened the question of if im doing it right.
When i use a point to point link i normally use a /29 subnet with 4 addresses used, 1 for each P2P device and then 1 for each side of the routers that connect to the WAN devices. After reading another artical it seems that everyone generally uses /31 subnerts for point to point links and i can see why but what i dont see is then how are the routers configured, do they also have a /31 subnet with the interfaces facing eachother?
I have looked at a few articles but none of them are like my setup, i have 1 main offices with 3 sites between then so its not a ring or a mesh, its just a point to point to point to point to point setup where each hop also has a point to multi point for out station telemetry.
The way i have been doing it for years works but i am curious to see if its the right way or if there is a better way, i have added a picture to show in brief how i configure each hop.
EDIT: i should also note that i dont understand how to access the management interface of the P2P device if its configured with a /31, do i then have to create static routes on the P2P and on the closest router?
Thanks for any help that can be provided.
