The difference between VLANs and VLAN interfaces   An SVI [   switched virtual interface ]  is normally found on switches (Layer 3 and Layer 2). With SVIs the switch recognizes the packet destinations that are local to the sending VLAN and switches those packets and packets destined for different VLANs are routed. Note:  An SVI cannot be activated unless the VLAN itself is created and at least one physical port is associated and active in that VLAN. Unless the VLAN is created there will be no spanning tree instance running hence the line protocol will be down for the SVI VLAN.

Configuration MPLS L2 VPN (VPLS) between two branches !!! Your tasks are: 1- R2(f0/0) not assign IP   R5(f0/1) no assign IP. 2- Apply routing protocol RIP v2 on R1 & R6 . 3- Apply OSPF on R2-R3-R4-R5, but R2 (23.0.0.0 & 2.2.2.2) no route with 16.0.0.0  and    R6 the same. 4- Company has two branches (16.0.0.1  -   16.0.0.6) 5- MPLS not need know network of customers into PE & P,  so customer network not need route   into core.
