HP Intelligent Management Center Licenses - Manual (Page 133)

There are three types of PEs that exist in a VPN:
•
Superstratum PEs (SPE)
•
Underlayer PEs (UPEs)
•
Middle-Level PEs (MPE)
The following rules apply:
•
If you import an SPE and a UPE, they exist as common PEs.
•
If you import an SPE and an MPE or import an MPE and a UPE, they exist as an SPE
and a UPE respectively.
•
If you import an MPE when an SPE and a UPE exist, these three devices exist as SPE,
MPE, and UPE respectively.
•
If an SPE, MPE, and UPE exist in the VPN and you remove the MPE only, the SPE and
UPE become common PEs.
•
If an SPE, MPE, and UPE exist in the VPN, when you remove the SPE or UPE, the
remaining devices are SPE and UPE respectively.
8.9 How do I discover a complete VPN network in MVM?
When selecting a PE to discover a VPN network, remove the VPN related to the CEs in the
VPN list and select PEs to be synchronized before auto-discovery.
8.10 Why does an invalid link exist in global access topology after auto-discovery?
After auto-discover is completed, if the original VPN link does not belong to any VPN, this
link is marked as invalid in the global access topology. The cause for this invalid link may
be:
•
Association between the interface and VRF on the PE is removed.
•
Definition of the VRF associated with the interface on the PE was modified and the RT
value in the new VRF does not belong to any VPN in MVM.
MVM does not manage an invalid link; therefore, it should be removed.
8.11 Why can't a PC be imported into MVM as a CE?
PEs and CEs managed by MVM must support SNMP. Check whether the PC supports SNMP.
If not, you can create a virtual CE to replace the PC and configure a real address for the
virtual CE interface.
8.12 In a VPN with the audit result being Consulted, why are PE-Core links displayed as unknown
in the topology?
PE-Core links and inter-HoPE links are defined when the devices are being imported and
MVM does not support dynamic interface updates. You can modify the interface on PE-Core
links and inter-HoPE links.
8.13 Why doesn't audit information display when inter-spoke unconnectivity in a Hub-Spoke VPN
is audited?
There are less than two spokes and no hub sites exist on the VPN network.
8.14 What networking schemes does MVM support?
Currently, the following networking schemes are supported:
•
Full-Mesh and Hub-Spoke on VPN type
•
VPN with VMCEs
•
VPN with HoPEs
•
VPN with dual-homed CEs based on device roles
8.15 When I deploy a connected link, why does it display in red in the topology?
