Run the display mpls l2vpn { export-route-target-list | import-route-target-list } command.
You can find that the route target is correctly configured. For example:
<Quidway> display mpls l2vpn import-route-target-list
import vpn target list: 744:7
<Quidway> display mpls l2vpn export-route-target-list
export vpn target list: 755:7

5.7 Configuring Inter-AS Martini VLL

If the MPLS backbone network on which a Martini VLL is set up spans multiple ASs, you can
configure the Martini VLL to be an inter-AS Martini VLL.

5.7.1 Establishing the Configuration Task

Before configuring an inter-AS Martini VLL, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
Applicable Environment
If the MPLS backbone network bearing the Martini VLL spans multiple ASs, you must configure
the inter-AS Martini VLL.
There are two solutions to the inter-AS Martini VLL:

Inter-AS Option A: This solution can be easily implemented. When the number of inter-
AS Martini VLLs on ASBRs is small, Option A is recommended.
Inter-AS Option C: In this solution, ASBRs do not need to create or maintain VCs. When
each AS has a large number of Martini L2VPN routes to be exchanged, Option C can be
used to prevent the ASBR from hindering the network extension.
Configuring static routes or IGP on the PE or P devices in the MPLS backbone network of
