DESCRIPTION
"A Label Switching Router (LSR) that
creates LDP sessions on ATM interfaces
uses the VCI or VPI/VCI field to hold the
LDP Label.
VCI values MUST NOT be in the 0-31 range.
The values 0 to 31 are reserved for other uses
by the ITU and ATM Forum. The value
of 32 can only be used for the Control VC,
although values greater than 32 could be
configured for the Control VC.
If a value from 0 to 31 is used for a VCI
the management entity controlling the LDP
subsystem should reject this with an
inconsistentValue error. Also, if
the value of 32 is used for a VC which is
NOT the Control VC, this should
result in an inconsistentValue error."

DESCRIPTION
"If the value of this object is greater than zero,

The value, when greater than zero, represents the
bandwidth of this MPLS interface (rounded to the
nearest 1,000) in units of 1,000 bits per second.
If the bandwidth of the MPLS interface is between
((n * 1000) - 500) and ((n * 1000) + 499), the value
of this object is n, such that n > 0.
If the value of this object is 0 (zero), this
means that the traffic over this MPLS interface is
considered to be best effort."

MplsLabel ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This value represents an MPLS label as defined in
[RFC3031], [RFC3032], [RFC3034], [RFC3035] and
[RFC3471].
The label contents are specific to the label being
represented, such as:
* The label carried in an MPLS shim header
(for LDP this is the Generic Label) is a 20-bit
number represented by 4 octets. Bits 0-19 contain
a label or a reserved label value. Bits 20-31
MUST be zero.
The following is quoted directly from [RFC3032].
There are several reserved label values:
i. A value of 0 represents the
'IPv4 Explicit NULL Label'. This label
value is only legal at the bottom of the
label stack. It indicates that the label
stack must be popped, and the forwarding
of the packet must then be based on the
IPv4 header.
ii. A value of 1 represents the
'Router Alert Label'. This label value is
legal anywhere in the label stack except at
the bottom. When a received packet
contains this label value at the top of
the label stack, it is delivered to a
local software module for processing.
The actual forwarding of the packet
is determined by the label beneath it
in the stack. However, if the packet is
forwarded further, the Router Alert Label
should be pushed back onto the label stack
before forwarding. The use of this label
is analogous to the use of the
'Router Alert Option' in IP packets
[RFC2113]. Since this label
cannot occur at the bottom of the stack,
it is not associated with a
particular network layer protocol.
iii. A value of 2 represents the
'IPv6 Explicit NULL Label'. This label
value is only legal at the bottom of the
label stack. It indicates that the label
stack must be popped, and the forwarding
of the packet must then be based on the
IPv6 header.
iv. A value of 3 represents the
'Implicit NULL Label'.
This is a label that an LSR may assign and
distribute, but which never actually
appears in the encapsulation. When an
LSR would otherwise replace the label
at the top of the stack with a new label,
but the new label is 'Implicit NULL',
the LSR will pop the stack instead of
doing the replacement. Although
this value may never appear in the
encapsulation, it needs to be specified in
the Label Distribution Protocol, so a value
is reserved.
v. Values 4-15 are reserved.
* The frame relay label can be either 10-bits or
23-bits depending on the DLCI field size and the
upper 22-bits or upper 9-bits must be zero,
respectively.
* For an ATM label the lower 16-bits represents the
VCI, the next 12-bits represents the VPI and the
remaining bits MUST be zero.
* The Generalized-MPLS (GMPLS) label contains a
value greater than 2^24-1 and used in GMPLS
as defined in [RFC3471]."

generic(1),

MplsLSPID ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A unique identifier within an MPLS network that is
assigned to each LSP. This is assigned at the head
end of the LSP and can be used by all LSRs
to identify this LSP. This value is piggybacked by
the signaling protocol when this LSP is signaled
within the network. This identifier can then be
used at each LSR to identify which labels are
being swapped to other labels for this LSP. This
object can also be used to disambiguate LSPs that
share the same RSVP sessions between the same
source and destination.
For LSPs established using CR-LDP, the LSPID is
composed of the ingress LSR Router ID (or any of
its own IPv4 addresses) and a locally unique
CR-LSP ID to that LSR. The first two bytes carry
the CR-LSPID, and the remaining 4 bytes carry
the Router ID. The LSPID is useful in network
management, in CR-LSP repair, and in using
an already established CR-LSP as a hop in
an ER-TLV.
For LSPs signaled using RSVP-TE, the LSP ID is
defined as a 16-bit (2 byte) identifier used
in the SENDER_TEMPLATE and the FILTER_SPEC
that can be changed to allow a sender to
share resources with itself. The length of this
object should only be 2 or 6 bytes. If the length
of this octet string is 2 bytes, then it must
identify an RSVP-TE LSPID, or it is 6 bytes,
it must contain a CR-LDP LSPID."

unknown(0) An unknown address type. This value
MUST be used if the value of the

used to indicate a TeHopAddress which
is not in one of the formats defined
below.
ipv4(1) An IPv4 network address as defined by

[RFC3291].
ipv6(2) A global IPv6 address as defined by

-- Private Addition
unnumv6(6) An unnumbered IPv6 interface index as
defined by the TeHopAddressUnnumV6
TEXTUAL-CONVENTION.
-- End Private Addition
Each definition of a concrete TeHopAddressType
value must be accompanied by a definition
of a TEXTUAL-CONVENTION for use with that
TeHopAddress.
To support future extensions, the TeHopAddressType
TEXTUAL-CONVENTION SHOULD NOT be sub-typed in
object type definitions. It MAY be sub-typed in
compliance statements in order to require only a
subset of these address types for a compliant
implementation.
Implementations must ensure that TeHopAddressType
objects and any dependent objects
(e.g., TeHopAddress objects) are consistent.
An inconsistentValue error must be generated
if an attempt to change a TeHopAddressType
object would, for example, lead to an
undefined TeHopAddress value that is
not defined herein. In particular,
TeHopAddressType/TeHopAddress pairs
must be changed together if the address
type changes (e.g., from ipv6(2) to ipv4(1))."

TeHopAddress ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Denotes a generic Tunnel hop address,
that is, the address of a node which
an LSP traverses, including the source
and destination nodes. An address may be
very concrete, for example, an IPv4 host
address (i.e., with prefix length 32);
if this IPv4 address is an interface
address, then that particular interface
must be traversed. An address may also
specify an 'abstract node', for example,
an IPv4 address with prefix length
less than 32, in which case, the LSP
can traverse any node whose address
falls in that range. An address may
also specify an Autonomous System (AS),
in which case the LSP can traverse any
node that falls within that AS.
A TeHopAddress value is always interpreted within
the context of an TeHopAddressType value. Every
usage of the TeHopAddress TEXTUAL-CONVENTION
is required to specify the TeHopAddressType object
which provides the context. It is suggested that
the TeHopAddressType object is logically registered
before the object(s) which use the TeHopAddress
TEXTUAL-CONVENTION if they appear in the
same logical row.
The value of a TeHopAddress object must always be
consistent with the value of the associated
TeHopAddressType object. Attempts to set a
TeHopAddress object to a value which is
inconsistent with the associated TeHopAddressType
must fail with an inconsistentValue error."
