As mentioned in the thread on OSPF packet drops, I have an MX80 dropping
OSPF packets during every commit, after adding ~1500 VLAN interfaces.
The major load seems to be ppmd, not rpd. On larger MX's, it is
apparently possible to distribute ppmd processing to the line cards.
Does that work on the

Alternative, is BFD cheap on an MX80? If I turn on BFD, I could set the
OSPF hello timers longer than the current 10 seconds. Of course that is
no good if BFD just makes even more work for the already-busy routing
engine.
AFAIK, at least as of 11.something, BFD

I've been using IPFIX on a few MX80's for a while now, the only impact
I've seen on the RE CPU is that it can spike to 100% during a commit, if
the router also has a full BGP table.
Otherwise the RE sits at 6%.
Using the default Jflow on the MX80's was horrible, the RE CPU would sit
around 70%

If you use inline IPFIX export, it's in trio, and should not
