That Broadcom chipset put me off of the NCS540.

That said, I'd imagine that Cisco's BGP-SD code is available for this
platform, which would alleviate this concern. The ASR920 only supports
20,000 entries in FIB, and we run a full table on it using BGP-SD.

The MX204 is an MPC7 line card in a rack, so it will do the full whack
in FIB, which is nice. If they can maintain that capability for an
"MX204-lite", we have a proper winner. My fear is that if Juniper were
to have a smaller cousin of the MX204 for dense, 1Gbps access, they may
go Broadcom, in which case they will position an ACX5000 of sorts, which
doesn't move the needle anywhere.
