There are other things that are required to support MPLS services than
just chip and software capability. Control plane, buffer memory, queue
That is why you would not find a lack of MPLS support in Ethernet
switches... you would find "broken" support, because the rest of the
hardware is not designed to deliver the same level of MPLS service scale
that a high-end router would; and the vendors make that very clear. An
Ethernet switch running MPLS can probably be an excellent P router, but
won't be an awesome PE router.
There are still some IP routing features we consider "basic" in bigger
routers that attract extra costs in Ethernet switches. Never mind MPLS.
Let's not confuse "MPLS no longer being expensive" with "MPLS being a
I find it hard to believe that SRv6 support will be enabled on low-end
devices like Ethernet switches by the traditional vendors. But hey, I
have been wrong before.
