Why can't the auto discover process finish sometimes?
During the auto discovery process network connection may disconnect occasionally. In this case the auto
discovery page cannot receive the auto discovery completion message. Hence it does not finish. If this
happens, click cancel auto discovery link in the page and redo auto discovery again.
Why is there a VPN shown in topology after it has been deleted in the Web page?
The message of VPN deletion is not received by topology due to a network problem. In this case reload
the topology tree.
Why do some SA links not belong to any VPN but they are shown as undeployment failure in
topology when some SA links are undeployed in a slot?
When you undeploy some SA links in a slot, some fail but their associated VPNs are marked invalid. This
is because the system is busy. Undeployment is not completed. In this case remove these SA links
manually.
What is the restriction of importing a P device to an AS in MPLS global network topology?
A P device can only exist in one AS.
On a PE device, two VPN instances are configured, associated with two interfaces respectively,
and set with the same IP address and mask for the interfaces. When the SA link information of
the PE device is viewed on the access topology, why do the IP address and mask of the interface
on one of the links are displayed as "N/A"?
The MPLS VPN Management module reads SA link information based on the standard MIB, which
requires that the interfaces on the same device cannot have the same IP address. As a result, MPLS VPN
Management cannot read duplicate IP address information and displays "N/A" instead. To prevent such
problems, do not configure two or more interfaces on a device with the same IP address.
Why doesn't global topology show the links between P devices and PE devices after P devices
are imported?
Add links between P devices and PE devices in the topology in either of the following ways:
• Use the Auto Link function in the global topology to add links between P devices and PE devices.
• If the IP address of an interface directly connecting the devices does not have a 30-bit mask, you
must manually add links in the topology.
When a VPN or SA is added as the monitor target of a PE interface (which is a VLAN interface),
a success message appears. Why is the actual operation result a failure?
The traffic monitor function allows you to map one physical interface to only one VLAN interface.
Otherwise, the system can give an inconsistent prompt message with the actual monitor status.
