with HREAP, need a router be at the remote edge of the WAN line to contact the WLC at the central data center?

we have a wlc in our data center.

we'd like to have a few 1131 ap's at a remote branch operate via the wlc.

in the HREAP docs i've seen, a router is indicated in the diagrams on both sides of the WAN.

our end-point equipment on both sides of the WAN is configured in bridge mode by our telcom carrier.

our remote branch is horizontal  w/ only 1 vlan, so we see no reason for a router.

is the router indicated in the HREAP docs mandatory, or just suggested?

tnx

Re: with HREAP, need a router be at the remote edge of the WAN l

I´m supposed is suggested, the Ap´s can work in a Layer 2 deployment but I not sure be the best way. With a L3 device you can avoid that unnecesary traffic generated by your APs flood through you L2 link between sites. I think this is one of the reasons to use a remote router, also seems the typical deployment.

Best regards.

It is not necessary if the remote network is in the same ip space on a layer 2 connection. Raul's comment is valid for any WAN connection. Layer 2 broadcast traffic can unnecessarily cross the WAN link and consume bandwidth. However, adding the AP at the remote site will not increase this traffic more than you have now.

I support this last answer. The fact to have a router or not is your decision but HREAP doesn't care at all. As long as the APs can have connectivity to the WLC, that's all that matters !

HTH,

Nicolas
