实验步骤
配置IP地址
以r2为例
[Huawei]sys r2
[r2]int l0
[r2-LoopBack0]ip address 2.2.2.2 32
[r2-LoopBack0]int g0/0/0
[r2-GigabitEthernet0/0/0]ip address 12.1.1.2 24
Jan 28 2024 13:30:23-08:00 r2 %%01IFNET/4/LINK_STATE(l)[3]:The line protocol IP
on the interface GigabitEthernet0/0/0 has entered the UP state.
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip address 23.1.1.1 24
Jan 28 2024 13:30:58-08:00 r2 %%01IFNET/4/LINK_STATE(l)[4]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
[r2-GigabitEthernet0/0/1]int g0/0/02
[r2-GigabitEthernet0/0/2]ip address 24.1.1.1 24
Jan 28 2024 13:31:11-08:00 r2 %%01IFNET/4/LINK_STATE(l)[5]:The line protocol IP
on the interface GigabitEthernet0/0/2 has entered the UP state.
R2、3、4、5、6建立OSPF协议
以R2为例：
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]network 23.1.1.1 0.0.0.0
[r2-ospf-1-area-0.0.0.0]network 24.1.1.1 0.0.0.0
[r2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0
配置BGP：
以R2为例：
[r2]bgp 100
[r2-bgp]router-id 2.2.2.2
[r2-bgp]peer 5.5.5.5 as-number 100
[r2-bgp]peer 5.5.5.5 connect-interface l0
[r2-bgp]peer 6.6.6.6 as-number 100
[r2-bgp]peer 6.6.6.6 connect-interface l0
R2、3、4、5、6配置MPLS
以r2为例
[r2]mpls
Warning: Please configure mpls lsr-id first.
[r2]mpls lsr-id 2.2.2.2
[r2]mpls
Info: Mpls starting, please wait... OK!
[r2-mpls]mpls ldp
[r2-mpls-ldp]q
[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]mpls
[r2-GigabitEthernet0/0/1]mpls ldp
[r2-GigabitEthernet0/0/1]int g0/0/2
[r2-GigabitEthernet0/0/2]mpls
[r2-GigabitEthernet0/0/2]mpls ldp
[r2]bgp 100
[r2-bgp]ipv4
[r2-bgp]ipv4-family vpnv4
[r2-bgp-af-vpnv4]peer 5.5.5.5 enable
[r2-bgp-af-vpnv4]peer 6.6.6.6 enable
[r2-bgp-af-vpnv4]peer 5.5.5.5 next-hop-local
[r2-bgp-af-vpnv4]peer 6.6.6.6 next-hop-local
