华为设备配置本地虚拟专用网互访

1. 配置IP地址
   [PE1-GigabitEthernet0/0/0]ip add 12.1.1.1 24
   [PE1-GigabitEthernet0/0/1]ip add 10.1.1.1 24
   [PE1-GigabitEthernet0/0/2]ip add 20.1.1.1 24
   [CE1-GigabitEthernet0/0/0]ip add 10.1.1.10 24
   [PE1-LoopBack0]ip add 1.1.1.1 32
   [CE2-GigabitEthernet0/0/0]ip add 20.1.1.20 24
   [PE2-GigabitEthernet0/0/0]ip add 12.1.1.2 24

   [CE4-GigabitEthernet0/0/0]ip add 40.1.1.40 24
2. 在PE设备上配置VPN实例&＃xff0c;将CE接入PE
   [PE1]ip vpn-instance vpna
   [PE1-vpn-instance-vpna]ipv4-family
   [PE1-vpn-instance-vpna-af-ipv4]route-distinguisher 100:1
   [PE1-vpn-instance-vpna-af-ipv4]vpn-target 111:1 export-extcommunity
   [PE1-vpn-instance-vpna-af-ipv4]vpn-target 111:1 222:2 import-extcommunity
   [PE1]ip vpn-instance vpnb
   [PE1-vpn-instance-vpnb]route-distinguisher 100:2
   [PE1-vpn-instance-vpnb-af-ipv4]vpn-target 222:2 export-extcommunity
   [PE1-vpn-instance-vpnb-af-ipv4]vpn-target 111:1 222:2 import-extcommunity
   [PE1-GigabitEthernet0/0/1]ip binding vpn-instance vpna
   [PE1-GigabitEthernet0/0/1]ip add 10.1.1.1 24
   [PE1-GigabitEthernet0/0/2]ip binding vpn-instance vpnb
   [PE1-GigabitEthernet0/0/2]ip add 20.1.1.1 24
   

[PE2]ip vpn-instance vpna
[PE2-vpn-instance-vpna]ipv4-family
[PE2-vpn-instance-vpna]route-distinguisher 100:1
[PE2-vpn-instance-vpna-af-ipv4]vpn-target 111:1 both
[PE2]ip vpn-instance vpnb
[PE2-vpn-instance-vpnb]ipv4-family
[PE2-vpn-instance-vpnb-af-ipv4]route-distinguisher 100:2
[PE2-vpn-instance-vpnb-af-ipv4]vpn-target 222:2 both
[PE2-GigabitEthernet0/0/1]ip binding vpn-instance vpna
[PE2-GigabitEthernet0/0/1]ip add 30.1.1.2 24
[PE2-GigabitEthernet0/0/2]ip binding vpn-instance vpnb
[PE2-GigabitEthernet0/0/2]ip add 40.1.1.2 24

3. 配置BGP&＃xff0c;将到本地CE的直连路由引入VPN路由表
   [PE1]bgp 100
   [PE1-bgp]ipv4-family vpn-instance vpna
   [PE1-bgp-vpna]import-route direct
   [PE1-bgp]ipv4-family vpn-instance vpnb
   [PE1-bgp-vpnb]import-route direct
   [PE2]bgp 100
   [PE2-bgp]ipv4-family vpn-instance vpna
   [PE2-bgp-vpna]import-route direct
   [PE2-bgp]ipv4-family vpn-instance vpnb
   [PE2-bgp-vpnb]import-route direct
4. 配置CE上的静态路由
   [CE1]ip route-static 0.0.0.0 0.0.0.0 10.1.1.1
   [CE2]ip route-static 0.0.0.0 0.0.0.0 20.1.1.1
   [CE3]ip route-static 0.0.0.0 0.0.0.0 30.1.1.2
   [CE4]ip route-static 0.0.0.0 0.0.0.0 40.1.1.2
5. 配置PE之间OSPF
   [PE1]ospf 1
   [PE1-ospf-1]area 0
   [PE1-ospf-1-area-0.0.0.0]network 12.1.1.0 0.0.0.255
   [PE1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   [PE1-ospf-1-area-0.0.0.0]network 20.1.1.0 0.0.0.255
   [PE1-ospf-1-area-0.0.0.0]network 1.1.1.1 0.0.0.0
   [PE2]ospf 1
   [PE2-ospf-1]area 0
   [PE2-ospf-1-area-0.0.0.0]network 30.1.1.0 0.0.0.255
   [PE2-ospf-1-area-0.0.0.0]network 40.1.1.0 0.0.0.255
   [PE2-ospf-1-area-0.0.0.0]network 12.1.1.0 0.0.0.255
   [PE2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0
6. 配置PE的MPLS基本能力和MPLS LDP&＃xff0c;建立LDP LSP
   [PE1]mpls lsr-id 1.1.1.1
   [PE1]mpls
   [PE1]mpls ldp
   [PE1-GigabitEthernet0/0/0]mpls
   [PE1-GigabitEthernet0/0/0]mpls ldp
   [PE2]mpls lsr-id 2.2.2.2
   [PE2]mpls
   [PE2]mpls ldp
   [PE2-GigabitEthernet0/0/0]mpls
   [PE2-GigabitEthernet0/0/0]mpls ldp
7. 在PE之间建立MP-IBGP对等体关系
   [PE1]bgp 100
   [PE1-bgp]peer 2.2.2.2 as-number 100
   [PE1-bgp]peer 2.2.2.2 connect-interface LoopBack 0
   [PE1-bgp]ipv4-family vpnv4
   [PE1-bgp-af-vpnv4]peer 2.2.2.2 enable
   [PE2]bgp 100
   [PE2-bgp]peer 1.1.1.1 as-number 100
   [PE2-bgp]peer 1.1.1.1 connect-interface LoopBack 0
   [PE2-bgp]ipv4-family vpnv4
   [PE2-bgp-af-vpnv4]peer 1.1.1.1 enable
8. 检查配置
