1.3.6.1.2.1.168.1.5.1.1 |
ipMcastRouteGroupAddressType |
INTEGER{unknown(0),ipv4(1),ipv6(2),ipv4z(3),ipv6z(4),dns(16)} |
not-accessible |
A value indicating the address family of the address contained in ipMcastRouteGroup. Legal values correspond to the subset of address families for which multicast forwarding is supported. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.168.1.5.1.2 |
ipMcastRouteGroup |
OCTET STRING{(0,255)} |
not-accessible |
The IP multicast group address which, when combined with the corresponding value specified in ipMcastRouteGroupPrefixLength, identifies the groups for which this entry contains multicast routing information. This address object is only significant up to ipMcastRouteGroupPrefixLength bits. The remaining address bits are set to zero. This is especially important for this index field, which is part of the index of this entry. Any non-zero bits would signify an entirely different entry. For addresses of type ipv4z or ipv6z, the appended zone index is significant even though it lies beyond the prefix length. The use of these address types indicate that this forwarding state applies only within the given zone. Zone index zero is not valid in this table. |
This object is implemented as defined in the corresponding MIB files. |
|

Unsigned32{(0,2040)} |
not-accessible |
The length in bits of the mask which, when combined with the corresponding value of ipMcastRouteGroup, identifies the groups for which this entry contains multicast routing information. The InetAddressType is given by ipMcastRouteGroupAddressType. For values 'ipv4' and 'ipv4z', this object must be in the range 4..32.

INTEGER{unknown(0),ipv4(1),ipv6(2),ipv4z(3),ipv6z(4),dns(16)} |
not-accessible |
A value indicating the address family of the address contained in ipMcastRouteSource. A value of unknown(0) indicates a non-source-specific entry, corresponding to all sources in the group. Otherwise, the value MUST be the same as the value of ipMcastRouteGroupType. |

ipMcastRouteRtAddress |
OCTET STRING{(0,255)} |
read-only |
The address portion of the route used to find the upstream or parent interface for this multicast forwarding entry. This address object is only significant up to ipMcastRouteRtPrefixLength bits. The remaining address bits are set to zero. For addresses of type ipv4z or ipv6z, the appended zone index is significant even though it lies beyond the prefix length.

ipMcastRouteRtType |
INTEGER{unicast(1),multicast(2)} |
read-only |
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 due (instead or in addition) 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 the Distance Vector Multicast Routing Protocol (DVMRP) or Multiprotocol BGP. |
This object is implemented as defined in the corresponding MIB files. |
|
1.3.6.1.2.1.168.1.5.1.18 |
ipMcastRouteOctets |
Counter64 |
read-only |
The number of octets contained in IP datagrams that were received from these sources and addressed to this multicast group address, and which were forwarded by this router. 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. |
The obtained value is fixed at 0. |
|
1.3.6.1.2.1.168.1.5.1.19 |
ipMcastRoutePkts |
Counter64 |
read-only |
The number of packets routed using this multicast route entry. 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. |
The obtained value is fixed at 0. |
|
1.3.6.1.2.1.168.1.5.1.20 |
ipMcastRouteTtlDropOctets |
Counter64 |
read-only |
The number of octets contained in IP datagrams 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. |
The obtained value is fixed at 0. |
|
1.3.6.1.2.1.168.1.5.1.21 |
ipMcastRouteTtlDropPackets |
Counter64 |
read-only |
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. |
The obtained value is fixed at 0. |
|
1.3.6.1.2.1.168.1.5.1.22 |
ipMcastRouteDifferentInIfOctets |
Counter64 |
read-only |
The number of octets contained in IP datagrams that this router has received from these sources and addressed to this multicast group address, which were dropped because they were received on an unexpected interface. For RPF checking protocols (such as PIM-SM), these packets arrived on interfaces other than ipMcastRouteInIfIndex, and were dropped because of this failed RPF check. (RPF paths are 'Reverse Path Forwarding' paths; the unicast routes to the expected origin of multicast data flows). Other protocols may drop packets on an incoming interface check for different reasons (for example, BIDIR-PIM performs a DF check on receipt of packets). All packets dropped as a result of an incoming interface check are counted here. If this counter increases rapidly, this indicates a problem. A significant quantity of multicast data is arriving at this router on unexpected interfaces, and is not being forwarded. For guidance, if the rate of increase of this counter exceeds 1% of the rate of increase of ipMcastRouteOctets, then there are multicast routing problems that require investigation. 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. |
The obtained value is fixed at 0. |
|
1.3.6.1.2.1.168.1.5.1.23 |
ipMcastRouteDifferentInIfPackets |
Counter64 |
read-only |
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 received on an unexpected interface. For RPF checking protocols (such as PIM-SM), these packets arrived on interfaces other than ipMcastRouteInIfIndex, and were dropped because of this failed RPF check. (RPF paths are 'Reverse Path Forwarding' path; the unicast routes to the expected origin of multicast data flows).

A significant quantity of multicast data is arriving at this router on unexpected interfaces, and is not being forwarded. For guidance, if the rate of increase of this counter exceeds 1% of the rate of increase of ipMcastRoutePkts, then there are multicast routing problems that require investigation. 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. |

1.3.6.1.2.1.168.1.5.1.24 |
ipMcastRouteBps |
Counter64 |
read-only |
Bits per second forwarded by this router using this multicast routing entry. This value is a sample; it is the number of bits forwarded during the last whole 1 second sampling period. The value during the current 1 second sampling period is not made available until the period is completed. The quantity being sampled is the same as that measured by ipMcastRouteOctets. The units and the sampling method are different. |
The obtained value is fixed at 0. |
