I dont think you can route the MAC address bellow. All standard IPv4 multicast addresses translate to 1st 3 bytes of the MAC to be 01-00-5E. This is confirmed in the WDS FAQ: Q. How do the WDS and the infrastructure APs in the WLAN communicate with each other?
A. The WDS and the infrastructure APs communicate over a multicast protocol called the Wireless LAN Context Control Protocol (WLCCP). These multicast messages cannot be routed. Therefore, a WDS and the associated infrastructure APs must be in the same IP subnetwork and on the same LAN segment. Between the WDS and the Wireless LAN Solution Engine (WLSE), WLCCP uses Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) on port 2887. When the WDS and WLSE are on different subnetworks, packet translation with a protocol like Network Address Translation (NAT) cannot occur. --- On Sun, 11/11/12, Shahin Mammadov <[email protected]> wrote: From: Shahin Mammadov <[email protected]> Subject: Re: [OSL | CCIE_Wireless] WDS To: "------" <[email protected]> Cc: "[email protected]" <[email protected]> Received: Sunday, November 11, 2012, 4:22 PM Hi, WDS communicates over the network using the Wireless LAN Context Control Protocol (WLCCP). This protocol uses the multicast destination address 01:40:96:ff:ff:c0 for advertisement and discovery of the WDS master. Once the master is discovered by WDS clients, then unicast UDP sessions are created over port 2887 to authenticate the WDS client and exchange information. Alternatively, the WDS master IP address may be configured statically in the WDS client if the master is not on the same subnet or if multicast routing is not enabled.

So far, I read the configuration guide of the current IOS versions, for the 1240AG for instance.

I also explored a couple of books : CCNA Wireless, CCNA Wireless from Todd Lamle without any luck.
