[j-nsp] jtree0 Memory full on MX480?

[Ivan Ivanov]

Hi,

The 'route' option on 'memory-enhanced' will give you some time before
upgrade to MPC. Actually you should be okay for quite a long time
considering the size of the table you have at the moment.

junos-software-jtree-memory-repartitioning.html

Note, that this will use the part of the memory reserved for filters (Jtree
segment 1) for storing route information. You that feature only if don't
have many filters configured.

Ivan,
