6. Optimizing performance¶

The default limit of 1 Million IPv4 routes may not be sufficient for a border router receiving several full BGP tables. The following example shows how to increase this to 3 Million.

border1> edit running
border1 running config# system fast-path limits ip4-max-route 3000000
border1 running config# commit

In case the router is overloaded and control packets are lost, the amount of CPU dedicated to prioritizing control plane vs. data plane traffic can be increased using the following command (default is 10%):

border1> edit running
border1 running config# system fast-path cp-protection budget 20
border1 running config# commit
