| Group |
| The IP multicast group address for which this entry contains multicast routing information. |
| Source |
| The network address which when combined with the corresponding value of ipMRouteSourceMask identifies the sources for which this entry contains multicast routing information. |
| SourceMask |
| The network mask which when combined with the corresponding value of ipMRouteSource identifies the sources for which this entry contains multicast routing information. |
| UpstreamNeighbor |
| The address of the upstream neighbor (e.g., RPF neighbor) from which IP datagrams from these sources to this multicast address are received, or 0.0.0.0 if the upstream neighbor is unknown (e.g., in CBT). |
| InIfIndex |
| 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 may be accepted on multiple interfaces (e.g., in CBT). Range: 0 to 2147483647 |
| UpTime |
| The time since the multicast routing information represented by this entry was learned by the router. |
| ExpiryTime |
| The minimum amount of time remaining before this entry will be aged out. The value 0 indicates that the entry is not subject to aging. |
| Pkts |
| The number of packets which this router has received from these sources and addressed to this multicast group address. |
| DifferentInIfPackets |
| The number of packets which this router has received from these sources and addressed to this multicast group address, which were dropped because they were not received on the interface indicated by ipMRouteInIfIndex. Packets which are not subject to an incoming interface check (e.g., using CBT) are not counted. |
| Octets |
| The number of octets contained in IP datagrams which were received from these sources and addressed to this multicast group address, and which were forwarded by this router. |
| Protocol |
| The multicast routing protocol via which this multicast forwarding entry was learned. Enumerations: - other (1)
- local (2)
- netmgmt (3)
- dvmrp (4)
- mospf (5)
- pimSparseDense (6)
- cbt (7)
- pimSparseMode (8)

| RtProto |
| The routing mechanism via which the route used to find the upstream or parent interface for this multicast forwarding entry was learned. Inclusion of values for routing protocols is not intended to imply that those protocols need be supported. Enumerations: - other (1)
- local (2)
- netmgmt (3)
- icmp (4)
- egp (5)
- ggp (6)
- hello (7)
- rip (8)
- isIs (9)
- esIs (10)
- ciscoIgrp (11)
- bbnSpfIgp (12)
- ospf (13)
- bgp (14)
- idpr (15)
- ciscoEigrp (16)
- dvmrp (17)
|
| RtAddress |
| The address portion of the route used to find the upstream or parent interface for this multicast forwarding entry. |
| RtMask |
| The mask associated with the route used to find the upstream or parent interface for this multicast forwarding entry. |
| RtType |
| The reason the given route was placed in the (logical) multicast Routing Information Base (RIB). A value of unicast means that the route would normally be placed only in the unicast RIB, but was placed in the multicast RIB (instead or in addition) due to local configuration, such as when running PIM over RIP. A value of multicast means that the route was explicitly added to the multicast RIB by the routing protocol, such as DVMRP or Multiprotocol BGP. Enumerations: |
| HCOctets |
| The number of octets contained in IP datagrams which were received from these sources and addressed to this multicast group address, and which were forwarded by this router. This object is a 64-bit version of ipMRouteOctets. |
