7 Frequently Asked Questions
MPLS VPN Management
Why does the batch process not deal with all selected objects?
Due to server performance capability it times out during the batch process. Therefore it does not deal
with the rest after the timeout. If this case happens, contact H3C to adjust system parameters.
Why does the system prompt Telnet failure when I import a device?
• Check whether MPLS VPN Management can communicate with the device normally.
• Check whether Telnet parameters on the platform are consistent with those configured on the device.
You can query or modify the parameters through detailed information of the devices on the
platform.
Why does the system prompt PE synchronization failure in global topology or access topology?
• Check whether MPLS VPN Management can communicate with the device normally.
• Check whether Telnet parameters on the platform are consistent with those configured on the device.
You can query or modify the parameters through detailed information of the devices on the
platform.
• Check whether MPLS VPN Management supports the device version. For details, refer to the version
description.
In MCE networking scheme, why can't PE-MCE links be discovered during auto discovery
process?
• Check whether MCE device is correctly configured, for example, whether an interface of PE is
associated with VRF.
• Check whether the MCE is imported correctly.
• Check whether more than two interfaces of MCE are associated with a same VRF, and the IP
address of one interface is in the same subnet with one of PE.
Why can't VPNs existing on the network be discovered during auto discovery process?
• The auto discovered PEs do not synchronize the latest VRF configurations of the device.
• Only one PE-CE link belonging to this VPN exists on a VPN network.
• The RT value of the VPN is the same as that of the existing VPN.
How should I add a VPN link in global or access topology?
In global topology, right-click the PE device to select Auto Discovery.
