[j-nsp] jtree0 Memory full on MX480?

[Chris Kawchuk]

I know that a ton of fixes on BGP convergence time son MX80 is definitely a reason to be 'moving up'... however as you're on RE-2000s on MX480 may not be applicable.

I see you're running DPC cards, have you considered shifting those links onto an MPC/Trio Card? (newer chip, more RAM, more horsepower, yadda yadda yadda =)..) DPC was EOL a while ago, and everything has been Trio (and now Trio-NG on the new -NG cards coming out now). As the FIB is pushed to hardware, it may be some silly DPC thing you're running into.

For things like Fusion or BNG or any other new/advanced/this-is-what-PLM-is-thinking functions, we're already putting in 14.2 on any new device we turn up, and have already started testing 15.1 for the new NG cards we will likely be buying. Rest of our network is now on 12.3R8 or 13.3 in many cases. (lots of BFD bugs have been squashed, some HQoS issues fixed, host-outbound-traffic for BFD keepalives now honour the c-o-s knobs, and are finally out of Queue 3 and into the Queue we want (7), etc... preventing starvation if you happen to have re-used Queue 3 as "not-so-high" priority, etc)... the list goes on.

It's not a case of "if it aint broke, don't fix it" once you get 4-5 years behind. You'll benefit from the years of "Oh, we finally fixed LLDP ascii decoding" stuff that ends up getting traction; plus JTAC would really really like it if you weren't on 11.4 =)
