What JunOS version are you running?
This is an M7i with RE-400, a full Internet routing table,
inet.0: 314795 destinations, 629302 routes (314784 active, 0 holddown, 19
hidden)
a handfull of MPLS L3VPNs (around 3K routes here) and a few interfaces,
running JunOS 9.5R3.7. Memory usage:
Routing Engine status:
Temperature 33 degrees C / 91 degrees F
CPU temperature 30 degrees C / 86 degrees F
DRAM 768 MB
Memory utilization 94 percent
Model RE-5.0
I'd say *any* RE-400 box with a full routing table and a recent JunOS
version is reason for worry. We have been unpleasantly surprised a
few times (boxes starting to show swap usage).
> Our units push ~200Mbit traffic, so they are nowhere near capacity CPU wise.
Packet forwarding is done in hardware on this platform, the CPU is not
involved.
