It does support a path to use an external TCAM if vendors do that, and will support 1M+ entries. It will be more expensive and the datapath will be slower which will impact the performance a bit.
I think you’ll see this make its way into something like a 48x10G/4x100G (or 40G) type platform but we’ll see.

I have no need for 100G, but 10G and 40G on a platform with deeper buffers sounds nice.

The processor is linerate above around 100 bytes per packet without external TCAM, supports 256K IPv4/64K IPv6 FIB entries (or mixed amounts). These chips are being used for high scale 100G, the initial NCS5508 linecard is a 36x100G QSFP28 one. Juniper has chosen to use their own silicon for most of their dense 100G platforms, but you’ll see these chips used by pretty much everyone else I imagine at some point in the next year.
