Huawei simulator ENSP - hcip - MPLS experiment

Topology ：

The experimental requirements ：

1. R1 And R5MPLS Virtual private line

2. R6 And R7MPLS Virtual private line

3. R7 You can visit R2/3/4 The loopback of

4. B1、B2 Using static routing protocol ;A1 Use RIP agreement ;A2 Use OSPF agreement ;A1、A2 Can pass R7 Visit the public network

5. All loopback addresses use 192.168.1.0;CE And PE Direct link usage 2.0、3.0;R5 Loopback 4.1;R6 Loopback 4.2

Ideas ：

 Configure router interface IP-> Configure the public network IGP agreement -> Configure the public network MPLS-> Configure the public network BGP agreement -> Configure private network IGP agreement -> To configure nat
