[j-nsp] EX4550 (Un-)known unicast flooding at session start for up to 100ms

[Aaron Gould]

Sorry to hear that.

I may have mentioned previously to someone else on the list... my EX4550's are rock solid... over 4 years uptime... I run our mirrored/redundant data centers behind them (hp 3par, hypervisors, etc) and our internet cdn caches behind them too...(Akamai, netflix, and that other one)

A pair of 4550's in top of racks virtual chassis'ed together 

Here they are...
