Delivery of Telemetry Data for AFT-Based Line Cards on MX Series Routers
Starting with Junos OS Release 20.4R1, a new concatenation of prefix and key delivery for telemetry is implemented for Modular Port Concentrator (MPC) line cards supporting Abstract Forwarding Table (AFT) (such as MPC10E or MPC11E line cards). The OpenConfig path is split in a different manner as compared to the syntax on other line cards.
The output that follows illustrates the changes in prefix and key delivery.
