Route Prefixes CPU utilization

Hi, @orlan_ortiz
for the first question, I think there is no such formula to calculate the CPU consumption of BGP route prefixes.
For the second question, I checked the documentation, no result is found, please contact with presale engineers to get the number of BGP routes supported.

Good day, @orlan_ortiz !

From the experience and observation:
- NE40E-X3A as Route-reflector can handle 3 BGP full views with about 50% memory consumption
(Again the numbers can vary if you use the same RD or different RD for VPN routes.)
- NE40E-X3A - as PE - could handle 1 million routes.

When received the BGP updates from peers (Full view) - NE40E routers put messages nto Adj-RIB one by one. After BGP messages are received from peer - can observed the CPU spike for upto 20-30% above the normal state. After BGP route-selection is finished - CPU is back to Normal level (+ or - 3%).

you can check the Memory used by BGP in the "Special" mode

Take care and have a great day!
