How to apply loadbalance on Eth-Trunk interface using MPLS VSI or VRF

        In my last article, I presented the way in which the R012 and higher versions of VRP manage to enable the switches of the S6720-HI and S6730 series a way to balance a load of MPLS content in an Eth-trunk interface. The article can be analyzed at this link. https://forum.huawei.com/enterprise/en/a-case-about-eth-trunk-load-balance-with-l2vpn/thread/600328-861

But in that article, I just presented the example of how to do it using MPLS L2VC (VPWS / PWE3) and several people questioned me about the configuration using VSI (VPLS) and L3VPN (VRF).

For VSI, we can use a command like that shown in the other article, the Flow-Label command. But the configuration must be done inside the VSI and not in the interface as in L2VC.

vsi teste

 pwsignal ldp

  vsi-id 1200

  flow-label both

  peer 10.99.99.100

#

For VRF, we must use another command, but it has the same effect on Eth-trunk loadbalance. In this case, the command used is as follows in the example:

#

ip vpn-instance vpn1

  ipv4-family

    route-distinguisher 100:1

    apply-label per-route
