Table 55: Job aid: show ip mroute route command output
Field Description
GROUP Indicates the IP multicast group for which this entry specifies a
next hop on an outgoing interface
SOURCE Indicates the network address that, when combined with the
corresponding value of ipMRouteNextHopSourceMask,
identifies the sources for which this entry specifies a next hop
on an outgoing interface.
SRCMASK Indicates the network mask, when combined with the
corresponding value of ipMRouteNextHopSource, identifies the
sources for which this entry specifies a next hop on an outgoing
interface.
UPSTREAM_NBR Indicates the address of the upstream neighbor from which IP
datagrams from these sources to this multicast address are
received, or 0.0.0.0 if the upstream neighbor is known.
IF Indicates the value of ifIndex for the interface on which IP
datagrams sent by these sources to this multicast address are
received. A value of 0 indicates that datagrams are not subject
to an incoming interface check, but can be accepted on multiple
interfaces (for example, in CBT).
EXPIR Indicates the minimum amount of time remaining before this
entry ages out. The value 0 indicates that the entry is not
subject to aging.
PROT Indicates the outgoing mechanism through which the switch
learns this route. For IP Multicast over Fabric Connect, this
value is sb-access or spb-network. Spb-access indicates the
datastream learned was from the UNI ports. Spb-network
indicates that the datastream learned was from the SPBM
cloud.
