The MPLS Topology Server discovers L3VPN-specific objects by probing the router and switch objects that are imported from IP Availability Manager. Discovery sources for MPLS L3VPNs identifies the L3VPN discovery sources.

L3VPN objects 1 |
|---|---|
| 1 SNMP-discovered objects are monitored for status, but CLI-discovered objects are not. |

| 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. |

Appendix A, “MIBs Accessed for Discovery and Remote Ping,” provides a description of the discovery MIB objects that are polled by an SNMP discovery probe. Appendix B, “CLI Commands Invoked for Discovery and LSP Ping,” provides a description of the commands that are invoked by a CLI discovery session.
