Layer 3 link with access to management interface

I am setting up a link between buildings that uses wireless links. I'm using Layer 3 routed ports on 2 3560 switches to handle the routing between sites. Normally I would just put these in a /30 and then the switches handle the rest.

However, the wireless access points have a web interface for managing them that I want to be able to access, but it's only available on the single NIC that also carries traffic.

What would be the best way of making this work? Should I make the link a /29 and give the access points an IP in the same range? If this is the case what do I use for the default gateway for the access points?

I have included a diagram to try to explain the issue clearer. The IP addresses in black are what I would do if this were a standard cable (and indeed this will work, but I wont be able to access the admin interface of the wireless AP) and the red ip addresses are the alternative if I use a /29 (but as I said, I'm not sure what to use for the default gateways)

Thanks for any / all help.



Layer 3 link with access to management interface

Hi Andrew,

Looking at your diagram the IP addressing is fine.

Give the left hand side AP a gateway of .1 and the right hand side .2

At leat then if the wireless link is down you should be able to web to the APs
from their own sides to fault etc.
