Specifying a maximum hop count for RPM and TWAMP probes

You can set a maximum hop count (TTL) for real-time performance monitoring (RPM) probes (both IPv4 and IPv6). This can be useful, for example, to restrict the scope of a given RPM probe so it cannot unintentionally monitor an alternative path to the destination, such as may occur following a BGP rerouting. Probes that exceed the number set for TTL are discarded. This TTL configuration is supported on Routing Engine-based RPM, MS-MPC based RPM, MS-MIC-based RPM, and Two-Way Active Management Protocol (TWAMP).
