Description

Enable specific prefix addresses to be periodically streamed from the target (source) to a collector. Only interfaces with those prefixes and their corresponding next-hop and next-hop group containers are exported to the IP OpenConfig Abstract Forwarding Table (oc-aft) collector. Reducing the set of interfaces to only those with prefixes of interest decreases the overall CPU and resource usage on Routing Engines, FPCs, and MPCs.

Export data from your source (target) to a collector using the sensor /network-instances/network-instance/afts/. When using prefix-filter mode, we recommend you use streaming subscription mode at a sampling frequency of 5 minutes or more and that all collectors have the same sampling frequency. If you are using non-prefix-filter mode, we recommend you use ON_CHANGE subscription mode. You can also export data using User Datagram Protocol (UDP).

Options

table-name

A forwarding information base (FIB) table.

prefix

An IPv4 (inet) or IPv6 inet6 address prefix.

Required Privilege Level

Release Information

Statement introduced in Junos OS 24.2R1 for MX2020 routers.
