Publication Date:  2016-05-17 Views:  25 Downloads:  0
Issue Description

Customer configure L3VPN on NE40E but he was unable to ping CE imediately after he add the "ip binding vpn-instance test" command on the interface that connects the CE device.

NE40E works as PE and it works on version V600R007C00SPC300. I will post some configuration snip.

Alarm Information
none.
Handling Process

As soon as customer is adding the "ip binding vpn-instance test" command under interface view the connectivity between CE and PE fails.

First thing we would to check is related to license content. L3VPN for NE40E is license controlled so it's important to check this part. Below we can see "display license" command content.

The license resource contains the enhance function which will transform the board LPUI-51-B to enhanced which will allow using L3VPN.

Root Cause

So license content include require function, but the customer didn't upgrade the slot accordingly.

Solution
To enable the content, its required to perform the following setup.


# Enable L3VPN and MVPN on the interface board in slot 7.
<HUAWEI> system-view
[HUAWEI] service-enhance slot 7
Info: Caution!!! Are you sure to do this operation?[Y/N]?y
Info: Enable the L3VPN and MVPN successfully!

Suggestions
if you plan to use L3VPN through multiple slots you will need to enable service-enhance command on all slots, but note that the license content should allow you configure the function for more than 1 slot.
