Figure 122 shows a sample configuration scenario of an MPLS L2VPN or Martini tunnel over VLAN over LAG. The sample topology shows a customer edge router, CE1, connected to a provider edge router, PE1 using a stacked VLAN (S-VLAN) tunnel.
Two LAG bundles, LAG1 and LAG2, are created to group multiple Ethernet interfaces on CE1 and PE1 respectively. A Martini tunnel from PE1 to PE2 is configured over LAG2 with a unique subinterface number assigned to the LAG bundle. The MPLS packets that are received on PE2, which is the remote router located at the other side of the service provider core, are processed. After PE2 processes the layer 2 Ethernet frames, they are sent to CE2, which is the customer edge device at the remote site.
