mplsTunnelHopTable

mplsTunnelHopTable

The mplsTunnelHopTable is used to indicate the hops, strict or loose, for an instance of an MPLS tunnel defined in mplsTunnelTable, when it is established via signaling, for the outgoing direction of the tunnel. Thus at a transit LSR, this table contains the desired path of the tunnel from this LSR onwards. Each row in this table is indexed by mpslsTunnelHopListIndex which corresponds to a group of hop lists or path options. Each row also has a secondary index mplsTunnelHopIndex, which indicates a group of hops (also known as a path option). Finally, the third index, mplsTunnelHopIndex indicates the specific hop information for a path option. In case we want to specify a particular interface on the originating LSR of an outgoing tunnel by which we want packets to exit the LSR, we specify this as the first hop for this tunnel in mplsTunnelHopTable.

The index of this table is mplsTunnelHopListIndex, mplsTunnelHopPathOptionIndex and mplsTunnelHopIndex.

Implemented Specifications

1.3.6.1.2.1.10.166.3.2.4.1.1

mplsTunnelHopListIndex

MplsPathIndex

Not-accessible

Primary index into this table identifying a particular explicit route object.

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

1.3.6.1.2.1.10.166.3.2.4.1.2

mplsTunnelHopPathOptionIndex

MplsPathIndex

Not-accessible

Secondary index into this table identifying a particular group of hops representing a particular configured path. This is otherwise known as a path option.

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

1.3.6.1.2.1.10.166.3.2.4.1.3

mplsTunnelHopIndex

MplsPathIndex

Not-accessible

Tertiary index into this table identifying a particular hop.

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

1.3.6.1.2.1.10.166.3.2.4.1.4

mplsTunnelHopAddrType

TeHopAddressType

Read-create

The Hop Address Type of this tunnel hop. The value of this object cannot be changed if the value of the corresponding mplsTunnelHopRowStatus object is 'active'. Note that lspid (5) is a valid option only for tunnels signaled via CRLDP.

The default value is ipv4.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.5

mplsTunnelHopIpAddr

TeHopAddress

Read-create

The Tunnel Hop Address for this tunnel hop. The type of this address is determined by the value of the corresponding mplsTunnelHopAddrType. The value of this object cannot be changed if the value of the corresponding mplsTunnelHopRowStatus object is 'active'.

The default value is 0x00000000.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.6

mplsTunnelHopIpPrefixLen

InetAddressPrefixLength

Read-create

If mplsTunnelHopAddrType is set to ipv4 (1) or ipv6 (2), then this value will contain an appropriate prefix length for the IP address in object mplsTunnelHopIpAddr. Otherwise this value is irrelevant and should be ignored.

The default value is 32.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.7

mplsTunnelHopAsNumber

TeHopAddressAS

read-create

If mplsTunnelHopAddrType is set to asnumber (3), then this value will contain the AS number of this hop. Otherwise the agent should set this object to zero-length string and the manager should ignore this.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.8

mplsTunnelHopAddrUnnum

TeHopAddressUnnum

read-create

If mplsTunnelHopAddrType is set to unnum (4), then this value will contain the interface identifier of the unnumbered interface for this hop.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.9

mplsTunnelHopLspId

MplsLSPID

read-create

If mplsTunnelHopAddrType is set to lspid (5), then this value will contain the LSPID of a tunnel of this hop.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.10

mplsTunnelHopType

INTEGER{strict(1),loose(2)}

Read-create

Denotes whether this tunnel hop is routed in a strict or loose fashion. The value of this object has no meaning if the mplsTunnelHopInclude object is set to 'false'.

The value list as below:

strict (1), loose (2).

Currently, the value supported is:
  • 1: loose
  • 2: strict

1.3.6.1.2.1.10.166.3.2.4.1.11

mplsTunnelHopInclude

TruthValue

Read-create

If this value is set to true, then this indicates that this hop must be included in the tunnel's path. If this value is set to 'false', then this hop must be avoided when calculating the path for this tunnel. The default value of this object is 'true', so that by default all indicated hops are included in the CSPF path computation. If this object is set to 'false' the value of mplsTunnelHopType should be ignored.

The default value is true (name).

Currently, the default value 2 is supported only.

1.3.6.1.2.1.10.166.3.2.4.1.12

mplsTunnelHopPathOptionName

SnmpAdminString

Read-create

The description of this series of hops as they relate to the specified path option. The value of this object SHOULD be the same for each hop in the series that comprises a path option.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.13

mplsTunnelHopEntryPathComp

INTEGER{dynamic(1),explicit(2)}

read-create

If this value is set to dynamic, then the user should only specify the source and destination of the path and expect that the CSPF will calculate the remainder of the path.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.14

mplsTunnelHopRowStatus

RowStatus

read-create

This variable is used to create, modify, or delete a row in this table. When a row in this table is in active (1) state, no objects in that row can be modified by the agent except mplsTunnelHopRowStatus and mplsTunnelHopStorageType.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.3.2.4.1.15

mplsTunnelHopStorageType

StorageType

read-create

The storage type for this Hop entry.

Currently, the maximum access is read-only.

Creation Restriction

The entries of this table cannot be created.

Modification Restriction

The entries of this table cannot be modified.

Deletion Restriction

The entries of this table cannot be deleted.

Access Restriction

To access this table, there must be a tunnel that passes through the device, and the tunnel is configured with mpls te record-route.
