The XMR/MLX are as much a "router" as the 6509 is, that is, they're not.
They're switches, and not very good ones at that.

I wholeheartedly agree.
We have MLX & XMR in production, the XMR was bought "because it could
route", only... it doesn't. The "advanced" Layer2 features on the MLX
are broken, we still (after over a year of "it's fixed, really") have
multi-interface RVI ports occasionally stop forwarding when any member
port is added/deleted/shutdown, the CLI is even clumsier and more
inconsistent than IOS, you can't have prefix-lists for ACLs, you can
only do either MPLS or 802.1q, not both on the same interface, you don't
got proper statistics for RVIs (only "bytes received" if you configure
it) and lots more that I forgot. The chassis & parts are way too cheap &
flimsy (mechanically), you can hardly get the line cards into the
chassis sometimes because of small variances here & there. SSH is broken
so horribly that we fell back to using telnet to manage the boxes. Last
not least, software updates are a nightmare, with a dozen or so image
files of very similiar names that go to different places, takes roughly
half an hour to just get all the software to the right places, with at
least one step blocking the CLI for ~5 minutes with no visible activity
whatsoever. Scary stuff. The only good thing about them is that they
boot quickly.
Executive summary: Foundry bad. Stay away.
We also have M320s & MX960s in production (as routers), the MX performs
admirably so far, multiple full tables, l2vpn, l3vpn,
flowSpec/flowFilter - everything we do on the M-series works on the MX
as well so far.
Kind regards,
Felix
