[mpls-linux-devel] VPLS support?

[David F. <da...@ab...>]

Hi,

What is the situation with VPLS support?

In particular, I believe that mpls-linux's existing Ethernet over MPLS 
works by virtue of hooking on ebtables. That is a case of modifying one 
ethernet packet on the way through. Whereas, in a scenario where there 
are three LERs (forming a VPLS), if an ethernet packet arrived from 
outside the VPN, then the LER would need to send two packets - one to 
each of the other two LERs in the VPLS VPN - each with a different MPLS 
label. Is there any kernel support for this sort of distribution in 
mpls-linux/ebtables/elsewhere?

I see from the archives that Pali was doing some work on this area late 
last year, although discussion seemed to revolve mainly around the 
signalling plane (quagga etc) and not this dataplane issue.

Thanks in advance,

David Fraser
