Can RSPAN be used on a MPLS or frame-relay hub-and-spoke topolgy?

hello wayne,

RSPAN is a LAN technology used to span traffic between two different switches. WHat exactly are u looking on an MPLS network ? do you wanna know if RSPAN can work between two locations connected thro EoMPLS or some other Layer 2 technologies ?? If, so, I guess it should work since the locations are in the same broadcast domain, unless the ISP does some kinda pruning for the RSPAN VLANs.

Hope this helps.. all the best.

thanks for your feedback. it looks like in order to do RSPAN, the switches must be trunked. as you mentioned it's a layer 2 technology. I was hoping that I can configure it over Layer3.
