Real-time performance monitoring over VPN routing and forwarding

Real-time performance monitoring (RPM) is now supported on SRX Series devices in addition to existing support on J Series devices.

VRF in a Layer 3 VPN implementation allows multiple instances of a routing table to coexist within the same device at the same time. Because the routing instances are independent, the same or overlapping IP addresses can be used without conflicting each other.

RPM ICMP and UDP probe with VPN routing and forwarding (VRF) has been improved. In previous releases, the RPM probes specified to a VRF table were not handled by the real-time forwarding process (FWDD-RT). In Junos OS Release 10.0, RPM probes specified to a VRF table are handled by the FWDD-RT, thereby providing more accurate results.

This feature supports RPM ICMP and UDP probes configured with routing instances of type VRF.
