[j-nsp] MX80 poor monitoring, packet loss to RE, SNMP not responding

[OBrien, Will]

Check your fxp0 configuration. You may be shipping return traffic out random interfaces...
We are leaning toward putting all production traffic inside a virtual routing instance/chassis and using the main routing instance just for management.

I have a pair of MX80's that both are very unreliable in terms of trying to
monitor them. Any traffic destined to the RE, be it ICMP or SNMP seems to
be very hit or miss. Sometimes SNMP won't respond, pinging it gives me
maybe 50% loss on average, but it passes traffic fine.

This causes issues with monitoring, false alerts, etc. I realize the
traffic destined for the RE is not as important, but the box is hardly
loaded and among maybe 50 other juniper devices I have, EX, SRX, only these
are giving me issues.

Can anybody give me any insight?

Thanks,
Morgan
