Re: [mpls-linux-general] mpls in layer 2 equipment (pc working as switch)

[Adrian P. <adr...@gm...>]

Hello Ricardo,

By design, MPLS was not intended to run on switches. It was intended to
replace IP lookup in core routers - so it expects it connects routers. You
don't need MPLS for layer 2 because switches don't do "best match" table
lookup (like IP routers)- so the operation is not so costly.

You can connect 2 PCs in a simulated LAN environment over MPLS by creating a
layer 2 MPLS tunnel that will transport your Layer 2 traffic between the
PCs. Look at the Layer 2 VPN examples in the documentation if this is what
you are looking for. However, your PC Switches will need IPs on some
interfaces to communicate.

Regards,
Adrian
