We're running an M7i (RE-5.0) as border router and I'm wondering what
typical / advised memory usage is on those. It's running 7.4R2.6.
Our M7i has:
- 7 BGP sessions (1 iBGP, 6 eBGP of which 5 full tables).
- OSPF (30 routes or something).
- light JFlow sampling.
Running the box with 512MB this puts memory usage on the RE at 85%. CFEB
memory usage is not that extreme:
Heap utilization 27 percent
Buffer utilization 25 percent
Total CPU DRAM 128 MB
- Are these accepted usage values or should I punt the RE memory to 768
- After upgrading to 7.5 memory usage was >100% (using swap) and I was
barely able to downgrade to 7.4R2.6. What additional memory usage can be
expected from upgrading to 7.5 and what benefits whould the upgrade offer
compared to 7.4?
