1.配置IP地址

2.OSPF配置

[r5-ospf-100-area-0.0.0.0]network 16.0.0.1 0.0.0.0
[r5-ospf-100-area-0.0.0.0]network 23.0.0.2 0.0.0.0

[r5-ospf-100-area-0.0.0.0]network 14.0.0.2 0.0.0.0

3.MPLS配置

[r2]mpls lsr-id 2.2.2.2

[r2-GigabitEthernet0/0/1]mpls ldp 	
[r2-GigabitEthernet0/0/2]mpls ldp

[r3]mpls lsr-id 3.3.3.3
[r3-mpls]mpl	
[r3-mpls]mpls ld		
[r3-GigabitEthernet0/0/0]mpls ldp 	
[r3-GigabitEthernet0/0/1]mpls ldp 
[r3-GigabitEthernet0/0/2]mpls ldp

[r4]mpls lsr-id 4.4.4.4	
[r4-mpls]mpls ld	
[r4-GigabitEthernet0/0/0]mpls ldp

[r6-GigabitEthernet0/0/0]mpls ldp 	
[r6-GigabitEthernet0/0/1]mpls ldp 	
[r6-GigabitEthernet0/0/2]mpls ldp

4.建立BGP

[r2-bgp]peer 5.5.5.5 as-number 100
[r2-bgp]peer 5.5.5.5 connect-interface LoopBack 0	
[r2-bgp]ipv4-family vpnv4	
[r2-bgp-af-vpnv4]peer 5.5.5.5 enable 
[r2-bgp]peer 6.6.6.6 as-number 100
[r2-bgp]peer 6.6.6.6 connect-interface LoopBack 0
[r2-bgp]ipv4-family vpnv4	
[r2-bgp-af-vpnv4]peer 6.6.6.6 enable 
[r2]route recursive-lookup tunnel

[r5-bgp]peer 2.2.2.2 as-number 100	
[r5-bgp]peer 2.2.2.2 connect-interface LoopBack 0
[r5-bgp]ipv4-family vpnv4
[r5-bgp-af-vpnv4]peer 2.2.2.2 enable 
[r5-bgp]peer 6.6.6.6 as-number 100	
[r5-bgp]peer 6.6.6.6 connect-interface LoopBack 0	
[r5-bgp]ipv4-family vpnv4	
[r5-bgp-af-vpnv4]peer 6.6.6.6 enable 
[r5]route recursive-lookup tunnel

[r6-bgp]peer 2.2.2.2 as-number 100	
[r6-bgp]peer 2.2.2.2 connect-interface LoopBack 0
[r6-bgp]ipv4-family vpnv4	
[r6-bgp-af-vpnv4]peer 2.2.2.2 enable 
[r6-bgp]peer 5.5.5.5 as-number 100
[r6-bgp]peer 5.5.5.5 connect-interface LoopBack 0	
[r6-bgp]ipv4-family vpnv4	
[r6-bgp-af-vpnv4]peer 5.5.5.5 enable 
[r6]route recursive-lookup tunnel

5.建立VPN
