Re: [mpls-linux-devel] VPLS support?

[<jl...@mi...>]

David,

The multi-point behavior you discuss below has not been implemented.
My thinking at this time is that we can use the linux bridging
core to accomplish this.  For this to occur a VPLS LSP needs to
be represented to the bridge core as an ethernet interface.
This could be accomplished with a modified version of the
mpls tunnel driver.

Due to the recent activity, I've picked up the project again.
I'm/we're in the process of getting all the fuctionality working on
a 2.6.32 kernel.  Once I get that accomplished I think this
would be a good place to do some additional work.
