Mailing List Archive: MX204 scale/performance

Hi

I'm stating network reorganization moving our infrastructure from
Cisco machines to bunch of MX204 routers.

I have few questions related to MX204 scale and performance:

1) How big ACLs are supported on MX204 ? (number of entries for all
ACLs configured).
2) I want to use lt- interfaces to address routing between default
(global) instance and logical-router. What performance (for IMIX
traffic) is supported for LT interfaces at MX204 ?
3) What FIB programming speed I can expect from MX204 (number of
routes per second - new BGP routes, withdraws)
4) Can I somehow prioritise which routes are programmed first in FIB ?
(based on BGP community or policy-statement)
5) How many flows for IPFIX are supported on MX204 ? Is IPFIX somehow
hardware accelerated or done pure in Intel CPU ?
6) Any recommendations for JunOS release ? My plan is to use latest
20.4, but maybe I'm wrong. Features used: Logical Routers, ISIS, a lot
of BGP, a lot of ACLe, RE ACL, uRPF, IPFIX

Thanks a lot
Rob

The MX204 is basically the MPC7E line card covered by some metal.

We are running 20.4R3 on ours. Not unhappy.

Mark.
