Why is audit information not displayed when inter-spoke unconnectivity in a Hub-Spoke VPN is
audited?
• There are less than two spokes.
• No hub sites exist on the VPN network.
What networking schemes does MPLS VPN Management support?
Currently the following networking schemes are supported: Full-Mesh and Hub-Spoke based on VPN
type, VPN with VMCEs, VPN with HoPEs, and VPN with dual-homed CEs based on device roles.
When I deploy a connected link, why is it displayed in red in the topology?
When you associate VPN with a PE interface, the interface automatically becomes down, and generates
a Down alarm. Therefore, the IMC considers this link failed.
• If you have configured a PE to send Traps to the IMC, the IMC displays the link as normal because
it received an interface up alarm when the interface automatically becomes up.
• If you do not configure the PE to send Traps to the IMC but configured polling interval, the IMC
displays the link as normal because it can obtain the real status of the link during the next polling.
• If you do not configure the PE to send Traps to the IMC nor configure polling interval, you can set
polling for the PE or manually synchronize the PE to make the link displayed as normal.
Why do only two links at most between AS and PEs appear in the topology?
• If too many links are displayed in a topology, the topology looks disorderly, and it is difficult for you
to view the links.
• The system considers the link on the PE enabled with MPLS as a connection to the core network.
However, when the PE is a P, there may be many links to other PEs. In this case, the system displays
only two of the links to avoid influence on monitoring of the network. If the two links displayed in the
topology are not what you need, you can select either of them, and modify the PE interface
connected to the link as the PE interface you want to view. In this way, you can view the link you
want to view.
In a PE to CE VPN link information page, both left and right interfaces of the link are all up, but
why is the status of this link unknown in topology?
The link status cannot be obtained because one of devices cannot be reached by ping, so the status of
this link is unknown.
Why am I unable to select sub-interfaces of a Cisco router during interface configuration for
service deployment?
Configure VLANs or enable MPLS for the sub-interfaces of the Cisco router and synchronize the device in
the MPLS VPN Management.
