ipMcastRouteNextHopTable

The (conceptual) table containing information on the next-hops on outgoing interfaces for routing IP multicast datagrams. Each entry is one of a list of next-hops on outgoing interfaces for particular sources sending to a particular multicast group address.

The indexes of the table are ipMcastRouteNextHopGroupAddressType, ipMcastRouteNextHopGroup, ipMcastRouteNextHopGroupPrefixLength, ipMcastRouteNextHopSourceAddressType, ipMcastRouteNextHopSource, ipMcastRouteNextHopSourcePrefixLength, ipMcastRouteNextHopIfIndex, ipMcastRouteNextHopAddressType, ipMcastRouteNextHopAddress.

1.3.6.1.2.1.168.1.6.1.1

ipMcastRouteNextHopGroupAddressType

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 ipMcastRouteNextHopGroup. 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.

1.3.6.1.2.1.168.1.6.1.2

ipMcastRouteNextHopGroup

OCTET STRING{(0,255)}

not-accessible

The IP multicast group address which, when combined with

the corresponding value specified in

ipMcastRouteNextHopGroupPrefixLength, identifies the groups

for which this entry contains multicast forwarding

information.

This address object is only significant up to

ipMcastRouteNextHopGroupPrefixLength 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.

1.3.6.1.2.1.168.1.6.1.3

ipMcastRouteNextHopGroupPrefixLength

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

ipMcastRouteNextHopGroupAddressType. For values 'ipv4' and

'ipv4z', this object must be in the range 4..32. For values

'ipv6' and 'ipv6z', this object must be in the range

8..128.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.4

ipMcastRouteNextHopSourceAddressType

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 ipMcastRouteNextHopSource.

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

ipMcastRouteNextHopGroupType.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.5

ipMcastRouteNextHopSource

OCTET STRING{(0,255)}

not-accessible

The network address which, when combined with the

corresponding value of the mask specified in

ipMcastRouteNextHopSourcePrefixLength, identifies the

sources for which this entry specifies a next-hop on an

outgoing interface.

This address object is only significant up to

ipMcastRouteNextHopSourcePrefixLength 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

source address 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.

1.3.6.1.2.1.168.1.6.1.6

ipMcastRouteNextHopSourcePrefixLength

Unsigned32{(0,2040)}

not-accessible

The length in bits of the mask which, when combined with

the corresponding value specified in

ipMcastRouteNextHopSource, identifies the sources for which

this entry specifies a next-hop on an outgoing interface.

The InetAddressType is given by

ipMcastRouteNextHopSourceAddressType. For the value

'unknown', this object must be zero. For values 'ipv4' and

'ipv4z', this object must be in the range 4..32. For values

'ipv6' and 'ipv6z', this object must be in the range

8..128.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.7

ipMcastRouteNextHopIfIndex

INTEGER

not-accessible

The ifIndex value of the interface for the outgoing

interface for this next-hop.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.8

ipMcastRouteNextHopAddressType

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 ipMcastRouteNextHopAddress.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.9

ipMcastRouteNextHopAddress

OCTET STRING{(0,255)}

not-accessible

The address of the next-hop specific to this entry. For

most interfaces, this is identical to

ipMcastRouteNextHopGroup. Non-Broadcast Multi-Access

(NBMA) interfaces, however, may

have multiple next-hop addresses out a single outgoing

interface.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.10

ipMcastRouteNextHopState

INTEGER{pruned(1),forwarding(2)}

read-only

An indication of whether the outgoing interface and next-

hop represented by this entry is currently being used to

forward IP datagrams. The value 'forwarding' indicates it

is currently being used; the value 'pruned' indicates it is

not.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.11

ipMcastRouteNextHopTimeStamp

TimeTicks

read-only

The value of sysUpTime at which the multicast routing

information represented by this entry was learned by the

router.

If this information was present at the most recent re-

initialization of the local management subsystem, then this

object contains a zero value.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.12

ipMcastRouteNextHopExpiryTime

TimeTicks

read-only

The minimum amount of time remaining before this entry will

be aged out. If ipMcastRouteNextHopState is pruned(1), the

remaining time until the prune expires and the state reverts

to forwarding(2). Otherwise, the remaining time until this

entry is removed from the table. The time remaining may be

copied from ipMcastRouteExpiryTime if the protocol in use

for this entry does not specify next-hop timers. The value

0 indicates that the entry is not subject to aging.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.13

ipMcastRouteNextHopClosestMemberHops

Unsigned32{(0,256)}

read-only

The minimum number of hops between this router and any member of this IP multicast group reached via this next-hop on this outgoing interface. Any IP multicast datagrams for the group that have a TTL (IPv4) or Hop Count (IPv6) less than this number of hops will not be forwarded to this next-hop. A value of 0 means all multicast datagrams are forwarded out the interface. A value of 256 means that no multicast datagrams are forwarded out the interface. This is an optimization applied by multicast routing protocols that explicitly track hop counts to downstream listeners. Multicast protocols that are not aware of hop counts to downstream listeners set this object to 0.

The actually supported value range is 1-255.

Currently, the value is an integer ranging from 1 to 255. The default value is 1.

1.3.6.1.2.1.168.1.6.1.14

ipMcastRouteNextHopProtocol

INTEGER{other(1),local(2),netmgmt(3),dvmrp(4),mospf(5),pimSparseDense(6),cbt(7),pimSparseMode(8),pimDenseMode(9),igmpOnly(10),bgmp(11),msdp(12)}

read-only

The routing mechanism via which this next-hop was learned.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.168.1.6.1.15

ipMcastRouteNextHopOctets

Counter64

read-only

The number of octets of multicast packets that have been forwarded using this route. 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 ipMcastRouteNextHopTimeStamp.

The obtained value is fixed at 0.

1.3.6.1.2.1.168.1.6.1.16

ipMcastRouteNextHopPkts

Counter64

read-only
