Marko I have read in some notes that :
"Spokes cannot resolve each other via InARP, because the endpoints dont have L2 circuits between them" I guess that is wrong and that Spokes can resolve each other since they are on different subnet. In short, if InARP is enabled in my cloud , my DTE will got all the DLCI in his show frame pvc | i DLCI right ? 2010/9/22 Marko Milivojevic <[email protected]> > Nicolas, > > FR switch DOES NOT participate in inverse ARP processes.
