Is your sizing concern just for the RIB, or also for FIB to sync up? The =
latter was a problem for us, but not the former. We also have inline-jflo=
w turned on and that is still a work-in-progress in terms of impacting perf=
ormance.
We are using MX104 for similar purposes for many months now, and with some =
tweaks in our procedures and configurations we found it to be acceptable. =
MX104 may not be able to process routes as fast as MX480, but MX480 is al=
so not instantaneous either so similar risks exist.
