L2L3-VPN-MCAST-MIB
Updated Nov 5, 2012AI MIB Summary
The L2L3-VPN-MCAST-MIB provides managed object definitions for monitoring multicast forwarding states, group membership, and tunnel interfaces within Layer 2 (VPLS) and Layer 3 (MVPN) VPN environments. It enables the collection of specific multicast session metrics, including active group counts, ingress/egress interface bindings, and protocol state transitions for VPLS and MVPN multicast traffic.
This MIB contains common managed object definitions for multicast in Layer 2 and Layer 3 VPNs, defined by [I-D.ietf-l2vpn-vpls-mcast] and RFC 6513/6514. Copyright (C) The Internet Society (2012).

jnxL2L3VpnMcastPmsiTunnelAttributeTableThis table is for advertised/received PMSI attributes,
to be referred to by I-PMSI or S-PMSI table entries SEQUENCE OF JnxL2L3VpnMcastPmsiTunnelAttributeEntry .jnxL2L3VpnMcastExperiment.1.1.1.1 |
jnxL2L3VpnMcastPmsiTunnelAttributeEntryAn entry in this table corresponds to an PMSI attribute
that is advertised/received on this router.
For BGP-based signaling (for I-PMSI via auto-discovery
procedure, or for S-PMSI via S-PMSI A-D routes),
they are just as signaled by BGP (RFC 6514 section 5,
'PMSI Tunnel attribute').
For UDP-based S-PMSI signaling for PIM-MVPN,
they're derived from S-PMSI Join Message
(RFC 6513 section 7.4.2, 'UDP-based Protocol')..
Note that BGP-based signaling may be used for
PIM-MVPN as well. JnxL2L3VpnMcastPmsiTunnelAttributeEntry .jnxL2L3VpnMcastExperiment.1.1.1.1.1 |
jnxL2L3VpnMcastPmsiTunnelAttributeFlagsFor UDP-based S-PMSI signaling for PIM-MVPN, this is 0.
For BGP-based I/S-PMSI signaling,
per RFC 6514 section 5, 'PMSI Tunnel Attribute':
The Flags field has the following format:
0 1 2 3 4 5 6 7
+-+-+-+-+-+-+-+-+
| reserved |L|
+-+-+-+-+-+-+-+-+
This document defines the following flags:
+ Leaf Information Required (L) OCTET STRING .jnxL2L3VpnMcastExperiment.1.1.1.1.1.1 |
jnxL2L3VpnMcastPmsiTunnelAttributeTypeFor BGP-based I/S-PMSI signaling for either PIM or BGP-MVPN,
per RFC 6514 section 5, 'PMSI Tunnel Attribute':
The Tunnel Type identifies the type of the tunneling technology used
to establish the PMSI tunnel. The type determines the syntax and
semantics of the Tunnel Identifier field. This document defines the
following Tunnel Types:
0 - No tunnel information present
1 - RSVP-TE P2MP LSP
2 - mLDP P2MP LSP
3 - PIM-SSM Tree
4 - PIM-SM Tree
5 - PIM-Bidir Tree
6 - Ingress Replication
7 - mLDP MP2MP LSP
For UDP-based S-PMSI signaling for PIM-MVPN, RFC 6513 does not
specify if a PIM provider tunnel is SSM, SM or Bidir,
and an agent can use either type 3, 4, or 5 based on its
best knowledge. JnxL2L3VpnMcastProviderTunnelType .jnxL2L3VpnMcastExperiment.1.1.1.1.1.2 |
jnxL2L3VpnMcastPmsiTunnelAttributeLabelFor BGP-based I/S-PMSI signaling,
per RFC 6514 section 5, 'PMSI Tunnel Attribute':
If the MPLS Label field is non-zero, then it contains an MPLS label
encoded as 3 octets, where the high-order 20 bits contain the label
value. Absence of MPLS Label is indicated by setting the MPLS Label
field to zero.
For UDP-based S-PMSI signaling for PIM-MVPN, this is not
applicable for now, as RFC 6513 does not specify
mpls encapsulation and tunnel aggregation with UDP-based
signaling. MplsLabel (MPLS-TC-STD-MIB) .jnxL2L3VpnMcastExperiment.1.1.1.1.1.3 |
jnxL2L3VpnMcastPmsiTunnelAttributeIdFor BGP-based signaling, as defined in RFC 6514 section 5,
'PMSI Tunnel Attribute'.
For UDP-based S-PMSI signaling for PIM-MVPN, RFC 6513 only
specifies the 'P-Group' address, and that is filled into
the first four octets of this field. OCTET STRING .jnxL2L3VpnMcastExperiment.1.1.1.1.1.4 |
jnxL2L3VpnMcastPmsiTunnelPointerIf the tunnel exists in some MIB table, this is the row pointer
to it.ro RowPointer (SNMPv2-TC) .jnxL2L3VpnMcastExperiment.1.1.1.1.1.5 |
jnxL2L3VpnMcastPmsiTunnelIfIf the tunnel has a corresponding interface, this is the
row pointer to the ifName table.ro RowPointer (SNMPv2-TC) .jnxL2L3VpnMcastExperiment.1.1.1.1.1.6 |
