Object
column SNMPv2-SMICounter64
The number of packets that this router has received from
these sources and addressed to this multicast group address,
which were dropped because the TTL (IPv4) or Hop Limit
(IPv6) was decremented to zero, or to a value less than
ipMcastInterfaceTtl for all next hops.
Discontinuities in this monotonically increasing value
occur at re-initialization of the management system.
Discontinuities can also occur as a result of routes being
removed and replaced, which can be detected by observing
the value of ipMcastRouteTimeStamp.
