BGP soft in - any negative effects?

Question:

I am familiar with inbound soft Catalyst 3560X  reconfiguration - but I do not know of any negative impacts this can have.  Can anyone say if there are any negatives about this?

Answer:

To my best knowledge, having inbound soft reconfiguration will increase your memory footprint and may increase the CPU utilization slightly as the BGP code will need to crawl through more entries in its table, skipping the ones-would-be-filtered-out. Otherwise, I am not aware of any outspokenly harmful effects.

Then again, if you do not know exactly you need it, you don't need it  BGP implementations support the Route Refresh functionality for years now, and turning the soft reconfiguration on does not bring any additional functionality from the viewpoint of re-applying inbound policies.  WS-C3560X-24T-L Price
