Discovery sources for MPLS LSPs through Discovery sources for MPLS L3VPNs identify by device/platform which class instances are monitored for status. As indicated in the tables, only SNMP-discovered objects are monitored for status.

Table 1. Discovery sources for MPLS LSPs

Device/platform

TE tunnels, TE LSPs, P2MP LSPs, and subLSPs 1

LDP LSPs 1

Cisco IOS

MPLS-TE-MIB and CLI

The MPLS Topology Server uses:

  • SNMP discovery to discover Cisco IOS TE tunnel and TE LSP objects.

  • CLI discovery to discover Cisco IOS nested link/node protected TE tunnel objects.

MPLS-LSR-MIB

If SNMP discovery fails or is not supported by the Cisco IOS device, the MPLS Topology Server uses CLI discovery to discover the LDP LSP objects.

Cisco IOX

MPLS-TE-STD-MIB and CLI

The MPLS Topology Server uses:

  • SNMP discovery to discover Cisco IOX TE tunnel and TE LSP objects.

  • CLI discovery to associate the primary TE LSPs with their backup/secondary TE LSPs.

MPLS-LSR-STD-MIB

If SNMP discovery fails or is not supported by the Cisco IOX device, the MPLS Topology Server uses CLI discovery to discover the LDP LSP objects.

Huawei

Not supported

CLI

Juniper M/T

JUNIPER-MPLS-MIB and CLI

The MPLS Topology Server uses:

  • SNMP discovery to discover Juniper TE tunnel objects that are configured for link/node protection.

  • CLI discovery to discover Juniper TE tunnel objects that are configured for path protection.

  • SNMP discovery to discover Juniper P2MP LSP and subLSP objects.

Table 4. Discovery sources for MPLS L3VPNs

Device/platform

L3VPN objects 1

Cisco IOS

MPLS-VPN-MIB

If SNMP discovery fails or is not supported by the Cisco IOS device, MPLS Manager uses CLI discovery to discover the L3VPN objects.

Cisco IOX

MPLS-L3VPN-STD-MIB

Huawei

MPLS-VPN-MIB

If SNMP discovery fails or is not supported by the Huawei device, MPLS Manager uses CLI discovery to discover the L3VPN objects.

Juniper M/T

JUNIPER-VPN-MIB and CLI

If SNMP discovery fails or is not supported by the Juniper M/T device, MPLS Manager uses CLI discovery to discover the L3VPN objects.

MPLS Manager also uses CLI discovery to discover multicast groups and their relationship to P2MP LSPs.

Juniper ERX
