·     1—Egress MPLS label.

·     2—Dynamic MPLS label.

·     3—L3VPN MPLS label.

·     4—VPWS MPLS label.

·     5—VPLS MPLS label.

·     6—IPv6 egress MPLS label.

·     7—SRGB MPLS label.

·     8—SRLB MPLS label.

·     9—L3VPN MPLS label.

System impact

Services might be affected if new services that use the type of MPLS labels are added.

2.     Execute the display mpls lsp statistics command to identify the protocols that generate too many LSPs. Execute the display mpls lsp protocol command to display the LSP information of these protocols, delete unnecessary LSPs, and then go to step 3.

3.     Check whether the hh3cMplsExtLabThreExceedClear notification has been generated.

¡     If yes, this issue has been resolved.

¡     If not, collect alarm information and configuration data, and then contact Technical Support for help.

1.3.6.1.4.1.25506.2.142.0.5	The tunnel selected for the VPN changed.	Recovery	Major	N/A	ON

 

Notification triggers

This notification is generated when the selected tunnel for the VPN changes.

Possible reasons are as follows:

·     The situation that no tunnel is selected for the VPN changes to the situation that a tunnel is selected for the VPN.

·     The situation that a tunnel is selected for the VPN changes to the situation that no tunnel is selected for the VPN.

·     The selected tunnel for the VPN is changed.

System impact

If the tunnel used by the VPN service changes from reachable to unreachable, or the situation that a tunnel is selected for the VPN changes to the situation that no tunnel is selected for the VPN, the VPN service is interrupted.

If the selected tunnel for the VPN is changed, the forwarding path for the VPN service traffic changes accordingly. Existing services on the new forwarding path might be affected.

Recommended action

To resolve this issue:

If the EcmpNum value in the notification is not 0, this notification is generated because the selected tunnel for the VPN is changed. Perform the following tasks to identify whether the change is desired:

1.     Execute the display ip vpn-instance instance-name name command to identify whether a tunnel policy is applied to the VPN.

¡     If the command output has the Tunnel Policy field, a tunnel policy is applied to the VPN. In this case, go to step 2.

¡     If the command output does not have the Tunnel Policy field, no tunnel policy is applied to the VPN. In this case, go to step 3.

2.     Execute the display tunnel-policy tunnel-policy-name command to check the tunnel policy. A tunnel policy uses tunnel selection methods in descending order of tunnel binding, preferred tunnel, and load sharing. In the command output, identify the tunnel selection methods used in the tunnel policy and find the tunnels that the VPN is expected to select through the tunnel policy.

¡     If the command output has the Binding-destination field, the tunnel binding method is used. The VPN is expected to select the tunnels in this field.

¡     If the command output has the Preferred paths field, the preferred tunnel method is used. The VPN is expected to select the tunnels in this field.

¡     If the command output has the Select-Seq field, the load sharing method is used. In this case, execute the display mpls tunnel all or display tunnel-info ipv6 all command to display information about the specified types of tunnels in the Select-Seq field. You can find the tunnels that the VPN is expected to select according to the tunnel policy and the tunnel information.

If the mpls te reserved-for-binding command is used on an MPLS TE tunnel interface, this MPLS TE tunnel cannot be used for load sharing.

3.     Execute the display fib vpn-instance vpn-instance-name command to check the FIB of the VPN instance. According to the value in the OutInterface/Token field, execute the display mpls forwarding nhlfe command to display information about the selected tunnels.

¡     If no tunnel policy is applied to the VPN, identify whether the selected tunnels are the expected tunnels. If yes, no action is required. If not, go to step 4.

¡     If a tunnel policy is applied to the VPN, identify whether the selected tunnels are the same as the expected tunnels found in step 2. If yes, no action is required. If not, go to step 4.

4.     If the issue persists, collect alarm information and configuration data, and then contact Technical Support for help.

If the EcmpNum value in the notification is 0, no tunnel is selected for the VPN. To resolve this issue:

1.     Execute the display ip vpn-instance instance-name name command to identify whether a tunnel policy is applied to the VPN.

¡     If the command output has the Tunnel Policy filed, a tunnel policy is applied to the VPN. In this case, go to step 2.

¡     If the command output does not have the Tunnel Policy field, no tunnel policy is applied to the VPN. In this case, go to step 3.

2.     Execute the display tunnel-policy tunnel-policy-name command to check the tunnel policy. A tunnel policy uses tunnel selection methods in descending order of tunnel binding, preferred tunnel, and load sharing. In the command output, identify the tunnel selection methods used in the tunnel policy and find the tunnels that the VPN is expected to select through the tunnel policy.

¡     If the command output has the Binding-destination field, the tunnel binding method is used. In this case, execute the display interface tunnel command to verify that the bound tunnel interfaces in the tunnel policy are up.

-     If a tunnel interface is up, enter tunnel interface view and execute the mpls te reserved-for-binding command. If the hh3cMplsExtTnlToVpnEvent notification is generated, this issue has been resolved. If the hh3cMplsExtTnlToVpnEvent notification is not generated, go to step 4.

-     If all tunnel interfaces are down, identify the interface down reason and bring up the interfaces according to TE related notifications. If the hh3cMplsExtTnlToVpnEvent notification is generated, this issue has been resolved. If the hh3cMplsExtTnlToVpnEvent notification is not generated, go to step 4.

¡     If the command output has the Preferred paths field, the preferred tunnel method is used. If the preferred tunnel is not available, the system automatically uses other methods to select tunnels. Unavailable of the preferred tunnel does not cause tunnel selection failure.

¡     If the command output has the Select-Seq field, the load sharing method is used. In this case, execute the display mpls tunnel all or display tunnel-info ipv6 all command to display information about the tunnels in the Select-Seq field and identify whether a qualified tunnel exists.

-     If no qualified tunnels are available, configure a qualified tunnel or change the tunnel policy applied to the VPN. If the hh3cMplsExtTnlToVpnEvent notification is generated, this issue has been resolved. If the hh3cMplsExtTnlToVpnEvent notification is not generated, go to step 4.

-     If a qualified tunnel is available, go to step 4.

If the mpls te reserved-for-binding command is used on an MPLS TE tunnel interface, this MPLS TE tunnel cannot be used for load sharing.

3.     Execute the display mpls lsp command to identify whether a public tunnel is available. If no public tunnel is available, modify the public tunnel configuration, for example, the LDP configuration, to establish a public tunnel.

¡     If the hh3cMplsExtTnlToVpnEvent notification is generated, this issue has been resolved.

¡     If the hh3cMplsExtTnlToVpnEvent notification is not generated, go to step 4.

4.     If the issue persists, collect alarm information and configuration data, and then contact Technical Support for help.
