Replicating Version 9 Flow Aggregation From M, MX and T Series Routers to Multiple Flow Servers
With this feature, you can configure up to eight flow servers to receive packets for a version 9 flow monitoring template. Once a flow server is configured to receive this data, it will also receive the following periodic version 9 flow monitoring updates:
Options data
Template definition
With Routing Engine-based sampling, if multiple collectors are configured with version 8 export format, all of them must use the same aggregation-type.
The option and template definition refresh period is configured on a per-template basis at the [edit services flow-monitoring] hierarchy level.
The following configuration example allows replication of version 9 export packets to two flow servers.

family inet {

flow-server 10.10.3.2 {

}
}
flow-server 172.17.20.62 {

version9 {

}
}
