Object
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.
