Question about mx80 ram usage.
The mx80 RE has only 2G ram. Which kind of features/scaling would you expect? I'm asking because we are facing some issues and i would like to know if those are expected or if there's a config error or bug etc.
The box1 (mx80) is a RR. It has approx 45 bgp sessions (mostly v4 and vpnv4, also some v6). 2 times full v4 table and one full v6 table. Mpls PE functions, a approx 15 vrfs etc. Ram usage reported by "show chas routing-eng" is 95%. I think this is quite high. Is this expected?
Calculating the ram usage so that "inact" ram is free yields over 10% lower figure.
Box2 is same hw, same junos, almost same features and number of routes. But 10% lower ram usage. There's no single process explaining the difference. E.g. rpd res/size figure is almost the same. I have not found the explanation looking at process lists.
Both boxes are running Junos 13.3R6.5.
Would MX104 be much better form this perspective? It has 4G ram.
Do you have any other tips on how to proceed the troubleshooting?
Thanks
