Spirent TestCenter : What is the maximum number of BGP routes that can be configured and advertised?

  • Spirent TestCenter
  • BGP
  • Recommended settings to advertise large number of routes

We can achieve 4.2 Billion routes provided the parameters are set correct.

Step 1 : Understanding the prefix distribution with larger network counts

          > We can't have 4.2 Billion prefixes of /24 with IPv4
          > At 64k updates MAX, it will take a minimum of 64K BGP updates to advertise all the prefixes
          > This is a good practice when advertising IPv6 prefixes too

Step 2  : Set Performance Mode and BGP Options

         > Enable BGP Route Packing

         > Disable 'View Routes' and 'Route Refresh'

Step 3 : Generate the right kind of prefixes, may import internet routes as well

         > Make sure to set the right prefix length
