Today, a colleague asked me if I knew of a way to refresh the routes in
a Juniper PFE, after having exhausted its SSRAM or heap memory, without
restarting it or otherwise causing impact to customer traffic. I didn't
have an answer to this, but I figured someone else might.
Note there is not a standby PFE which can be switched to for a reboot of
the active one. With enough config hacking, one could trick the box
into doing it via the forwarding-table export policy; but simple changes
that don't really alter the routes computed for FIB do not work.
