Hcip experiment (14)

  One , First of all mpls vpn Backbone network configuration public network IP Address
R2

R3

 R4

 

 

Two , Use OSPF Access to the public network IP The routing entry for

 ospf 1 router-id 2.2.2.2 
 area 0.0.0.0 
 network 2.2.2.2 0.0.0.0 
 network 23.0.0.0 0.0.0.255

3、 ... and , establish mlps

[r2]mpls lsr-id 2.2.2.2  ---mpls Of router-id, For the real of the local device ip Address , And neighbors can reach
[r2]mpls   --- Global on mpls agreement
[r2]mpls ldp  --- Activate LDP agreement
[r2-GigabitEthernet0/0/1]mpls  --- Interface on mpls agreement
[r2-GigabitEthernet0/0/1]mpls ldp  --- Interface activation LDP agreement
Be careful ：MLPS Every interface of the domain should be turned on

 

Four , To configure MPLS VPN
（ One ） To configure R2 Of vpn

To configure vpn a
[r2]ip vpn-instance a   --- Create a a Of vrf Space
[r2-vpn-instance-a]route-distinguisher 100:100  --- To configure RD value
[r2-vpn-instance-a-af-ipv4]vpn-target 100:1 ?   --- To configure PT value
  both                    --- Outbound and inbound are the same  
  export-extcommunity     --- Configure outbound RT
  import-extcommunity     --- Configure inbound RT
[r2-vpn-instance-a-af-ipv4]vpn-target 100:1 both 
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip binding vpn-instance a  --- Related to vrf Space
[r2-GigabitEthernet0/0/0]ip address 192.168.2.2 24  --- Configuration private ip Address

To configure vpn b
[r2]ip vpn-instance b
[r2-vpn-instance-b]route-distinguisher 200:200
[r2-vpn-instance-b-af-ipv4]vpn-target 200:1 both 
[r2]int g0/0/2
[r2-GigabitEthernet0/0/2]ip binding vpn-instance b
[r2-GigabitEthernet0/0/2]ip address 172.16.2.2 24

（ Two ） To configure R4 Of vpn

To configure vpn a
[r4]ip vpn-instance a
[r4-vpn-instance-a]route-distinguisher 100:100
[r4-vpn-instance-a-af-ipv4]vpn-target 100:1 both 
[r4]int g0/0/1
[r4-GigabitEthernet0/0/1]ip binding vpn-instance a
[r4-GigabitEthernet0/0/1]ip address 192.168.3.2 24

To configure vpn b
[r4]ip vpn-instance b
[r4-vpn-instance-b]route-distinguisher 200:200    
[r4-vpn-instance-b-af-ipv4]vpn-target 200:1 both 
[r4]int g0/0/2
[r4-GigabitEthernet0/0/2]ip binding vpn-instance b
[r4-GigabitEthernet0/0/2]ip address 172.16.3.2 24

（ 3、 ... and ） To configure r1,r5,r6,r7IP Address

[r1-GigabitEthernet0/0/0]ip address 192.168.2.1 24
[r1-LoopBack0]ip address 192.168.1.1 24
[r5-GigabitEthernet0/0/0]ip address 192.168.3.1 24
[r5-LoopBack0]ip address 192.168.4.1 24
[r6-GigabitEthernet0/0/0]ip address 172.16.2.1 24
[r6-LoopBack0]ip address 172.16.1.1 24
[r7-GigabitEthernet0/0/0]ip address 172.16.3.1 24
[r7-LoopBack0]ip address 172.16.4.1 24

notes ： In relation to vrf Interface cannot be configured before space ip, Otherwise, the direct route of the address will enter the public route table

[r2]display  ip routing-table vpn-instance a  --- View the private routing table in the space

[r2]ping -vpn-instance  a  192.168.2.1   The normal test will query the records in the public routing table ; This command is based on VRF Space

5、 ... and , To configure BGP Jianlin

R2:
[r2]bgp 1
[r2-bgp]router-id 2.2.2.2
[r2-bgp]peer 4.4.4.4 as-number 1
[r2-bgp]peer 4.4.4.4 connect-interface LoopBack  0
[r2-bgp]ipv4-family vpnv4   --- Get into vpnv4
[r2-bgp-af-vpnv4]peer 4.4.4.4 enable  --- Turn on VPNv4 Neighborhood building
R4:
[r4]bgp 1
[r4-bgp]router-id 4.4.4.4
[r4-bgp]peer 2.2.2.2 as-number 1
[r4-bgp]peer 2.2.2.2 connect-interface LoopBack 0
[r4-bgp]ipv4-family vpnv4
[r4-bgp-af-vpnv4]peer 2.2.2.2 enable

6、 ... and , to R1-R2 and R4-R5 Configure static , So that they can access each other
（ One ） Configure static routing

R1：
[r1]ip route-static 192.168.3.0 24 192.168.1.2
[r1]ip route-static 192.168.4.0 24 192.168.1.2
R2：
[r2]ip route-static vpn-instance a 192.168.1.0 192.168.2.1
R4:
[r4]ip route-static vpn-instance a 192.168.4.0  24 192.168.3.1
R5:
[r5]ip route-static 192.168.1.0 24 192.168.3.2 
[r5]ip route-static 192.168.2.0 24 192.168.3.2

（ Two ） Get into BGP Publish route

[r2]bgp 1
[r2-bgp]ipv4-family vpn-instance a
[r2-bgp-a]import-route static 
[r2-bgp-a]import-route direct 

[r4]bgp 1
[r4-bgp]ipv4-family vpn-instance a
[r4-bgp-a]import-route static 
[r4-bgp-a]import-route direct

 

7、 ... and ,R6 adopt RIP Pass private network route to PE equipment ,R7 adopt osPF Pass private network route to PE equipment ,

R2——R6：rip                      
[r2]rip 1 vpn-instance b
[r2-rip-1]v 2
[r2-rip-1]network 172.16.0.0
[r6]rip
[r6-rip-1]v 2
[r6-rip-1]network 172.16.0.0
R4—R7: ospf
[r4]ospf 2 vpn-instance b router-id 4.4.4.4
[r4-ospf-2]a 0
[r4-ospf-2-area-0.0.0.0]network 172.16.0.0 0.0.255.255
[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]a 0
[r7-ospf-1-area-0.0.0.0]net    
[r7-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255

Double point release
[r2]rip
[r2-rip-1]import-route bgp 1
[r2]bgp 1
[r2-bgp]ipv4-family vpn-instance b
[r2-bgp-b]import-route rip 1

[r4]bgp 1
[r4-bgp]ipv4-family vpn-instance b
[r4-bgp-b]import-route ospf 2
[r4]ospf 2
[r4-ospf-2]import-route bgp

8、 ... and , Configure a default , send R7 You can visit R2/R3/R4 Loopback .
