Cisco XR 1200 series User Manual

Usage Guidelines
A retry occurs when either an echo reply was not received on time for an outstanding echo request, or when
no selectors are found for a given path by a transit router.
When a selector value is configured in MPLSLM configuration mode, the maximum selector specified must
be larger than that value. In such a scenario, the range of selectors used for path discovery is set by the two
values.
When the interval time is zero, a new echo request is sent after the previous echo retry was received.
