They are holding up pretty well for us, mainly because we do a lot more
BGP on MX480's than on MX204's. We use the MX204's mainly for peering
and CDN gateways. Where we use them for edge customers, it's a handful
of BGP sessions.

On MX480 16GB RE's running two full BGP feeds but hundreds of customer
sessions, Add-Paths really eats into RAM. We've had to upgrade some of
the busier routers from 16GB to 64GB RE's, especially on later versions
of code where ROV can also bite into memory on boxes carrying lots of
BGP sessions.

Mark.
