Description: The number of IP packets of version cipUrpfIfIpVersion failing the URPF check but given a reprieve and not dropped by the managed device. Depending on the device configuration and capabilities, the following cases may cause incrementing of the counter: - if the managed device is configured to allow self-pings and the managed device pings itself. - if the managed device is configured for loose URPF (if any interface has a route to the source), and the strict case fails while the loose case passes. - DHCP Request packets (src 0.0.0.0 dst 255.255.255.255) will pass after initially being marked for drop. - RIP routing on unnumbered interfaces will pass after initially being marked for drop. - multicast packets will pass after initially being marked for drop - ACL's can be applied to permit packets after initially being marked for drop.

Discontinuities in the value of this variable can occur at re-initialization of the management system, and at other times as indicated by the values of cipUrpfIfDiscontinuityTime.
