Hello,
Does anyone happens to know what are memory requirements
for cisco NSE-1 supposed to carry full BGP table (~100000 routes)?
Is it known phenomenon that memory requirements for BGP process(es)
are much higher in IOS 12.2 than in IOS 12.1?
Or maybe this is Service Provider trim causing this?
Basically BGP router process on box running IOS 12.1 is holding
~45MB of memory, while on box working in comparable condition,
but wth IOS upgraded to 12.2 the same BGP router process is holding
~73MB of memory. Is it normal and expected?
In other words: Is it a feature, or is it a bug :-) ?
Thank you for sharing your experiences in this matter,
Przemek
Please see what I have noticed after upgrading IOS from 12.1 to 12.2:
