单域MPLS 虚拟私有网络的整个详解配置过程（可跟做）（单域名和多域名的区别）
单域MPLS 虚拟私有网络的整个详解配置过程（可跟做）（单域名和多域名的区别）
1.PE1和P和PE2之间跑IGP协议
运营商里面首选的还是ISIS协议我们实验的话，用的是OSPF协议
R3的IP地址和OSPF配置
[R3]display ip int brief *down: administratively down ^down: standby (l): loopback (s): spoofing The number of interface that is UP in Physical is 5 The number of interface that is DOWN in Physical is 1 The number of interface that is UP in Protocol is 5 The number of interface that is DOWN in Protocol is 1 Interface IP Address/Mask Physical Protocol GigabitEthernet0/0/0 13.1.1.3/24 up up GigabitEthernet0/0/1 23.1.1.3/24 up up GigabitEthernet1/0/0 34.1.1.3/24 up up GigabitEthernet2/0/0 unassigned down down LoopBack0 3.3.3.3/32 up up(s) NULL0 unassigned up up(s) [R3]dis current-configuration configuration ospf [V200R003C00] # ospf 1 router-id 3.3.3.3 area 0.0.0.0 network 3.3.3.3 0.0.0.0 network 34.1.1.0 0.0.0.255 # return [R3]
R4的IP地址和OSPF配置
[R4]display ip int brief *down: administratively down ^down: standby (l): loopback (s): spoofing The number of interface that is UP in Physical is 4 The number of interface that is DOWN in Physical is 0 The number of interface that is UP in Protocol is 4 The number of interface that is DOWN in Protocol is 0 Interface IP Address/Mask Physical Protocol GigabitEthernet0/0/0 34.1.1.4/24 up up GigabitEthernet0/0/1 45.1.1.4/24 up up LoopBack0 4.4.4.4/32 up up(s) NULL0 unassigned up up(s) [R4]display current-configuration configuration ospf [V200R003C00] # ospf 1 router-id 4.4.4.4 area 0.0.0.0 network 4.4.4.4 0.0.0.0 network 34.1.1.0 0.0.0.255 network 45.1.1.0 0.0.0.255 # return
R5的IP地址和OSPF的配置
2.检查结果
在R4上面检查我们的结果
[R4]display ospf peer brief OSPF Process 1 with Router ID 4.4.4.4 Peer Statistic Information ---------------------------------------------------------------------------- Area Id Interface Neighbor id State 0.0.0.0 GigabitEthernet0/0/0 3.3.3.3 Full 0.0.0.0 GigabitEthernet0/0/1 5.5.5.5 Full ----------------------------------------------------------------------------
在R4上面检查是否通过OSPF学习到R3和R5network发布的路由
[R4]display ip routing-table protocol ospf
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : OSPF
Destinations : 2 Routes : 2
OSPF routing table status :
3.PE1和P和PE2之间跑MPLS协议和MPLS LDP协议
原因就是解决BGP跨设备路由黑洞问题
R3的MPLS和MPLS LDP的配置
全局下的配置
# mpls lsr-id 3.3.3.3 mpls mpls ldp # 接口下的配置 # interface GigabitEthernet1/0/0 mpls mpls ldp #
R4的MPLS和MPLS LDP的配置
全局下的配置
# mpls lsr-id 4.4.4.4 mpls mpls ldp # 接口下的配置 # interface GigabitEthernet0/0/0 mpls mpls ldp # interface GigabitEthernet0/0/1 mpls mpls ldp #
R5的MPLS和MPLS LDP的配置
全局下的配置
# mpls lsr-id 5.5.5.5 mpls mpls ldp # 接口下的配置 # interface GigabitEthernet0/0/0 mpls mpls ldp #
4.检查MPLS LDP关系
在R4上面查看于R3和R5之间的LDP关系
[R4]display mpls ldp session all LDP Session(s) in Public Network Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM) A '*' before a session means the session is being deleted. ------------------------------------------------------------------------------ PeerID Status LAM SsnRole SsnAge KASent/Rcv ------------------------------------------------------------------------------ 3.3.3.3:0 Operational DU Active 0000:00:36 148/148 5.5.5.5:0 Operational DU Passive 0000:00:36 147/147 ------------------------------------------------------------------------------ TOTAL: 2 session(s) Found.
在R5上面分别查看是否对3.3.3.3/32分发标签
在R3上面分别查看是否对5.5.5.5/32分发标签
5.在PE1和PE2上面分别配置VRF和RD和RT
在PE1和PE2上面分别对A公司的分部和总部进行定义VRF
PE1上面定义A公司分部
# ip vpn-instance VPN13 ipv4-family route-distinguisher 1:3 vpn-target 100:300 export-extcommunity vpn-target 100:300 import-extcommunity #
PE2上面定义A公司总部
# ip vpn-instance VPN75 ipv4-family route-distinguisher 7:5 vpn-target 100:300 export-extcommunity vpn-target 100:300 import-extcommunity #
在PE1和PE2上面分别对A公司的分部和总部进行定义VRF调用
PE1上面定义A公司分部VRF的调用
# interface GigabitEthernet0/0/0 ip binding vpn-instance VPN13 ip address 13.1.1.3 255.255.255.0 # 注意：调用VRF的时候，该接口下的配置就会消失 # interface GigabitEthernet0/0/0 ip address 13.1.1.3 255.255.255.0 # [R3-GigabitEthernet0/0/0]ip binding vpn-instance VPN13 Nov 2 2019 14:59:50-08:00 R3 %%01IFNET/4/LINK_STATE(l)[3]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the DOWN state. Info: All IPv4 related configurations on this interface are removed! Info: All IPv6 related configurations on this interface are removed! [R3-GigabitEthernet0/0/0]dis this [V200R003C00] # interface GigabitEthernet0/0/0 ip binding vpn-instance VPN13 # [R3-GigabitEthernet0/0/0]ip address 13.1.1.3 24 Nov 2 2019 15:00:02-08:00 R3 %%01IFNET/4/LINK_STATE(l)[4]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the UP state. [R3-GigabitEthernet0/0/0]
怎么样查看VRF的路由呢？
[R3]display ip routing-table vpn-instance VPN13 Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: VPN13 Destinations : 6 Routes : 6 Destination/Mask Proto Pre Cost Flags NextHop Interface 13.1.1.0/24 Direct 0 0 D 13.1.1.3 GigabitEthernet0/0/0 13.1.1.3/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 13.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 [R3]
在PE1上面的全局路由表里面根本就看不到13网段的任何路由
[R3]display ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 11 Routes : 11 Destination/Mask Proto Pre Cost Flags NextHop Interface 3.3.3.3/32 Direct 0 0 D 127.0.0.1 LoopBack0 4.4.4.4/32 OSPF 10 1 D 34.1.1.4 GigabitEthernet1/0/0 5.5.5.5/32 OSPF 10 2 D 34.1.1.4 GigabitEthernet1/0/0 34.1.1.0/24 Direct 0 0 D 34.1.1.3 GigabitEthernet1/0/0 34.1.1.3/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 34.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 45.1.1.0/24 OSPF 10 2 D 34.1.1.4 GigabitEthernet1/0/0 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 [R3]
PE2上面定义A公司总部VRF的调用
# interface GigabitEthernet1/0/0 ip binding vpn-instance VPN75 ip address 57.1.1.5 255.255.255.0 # [R5]display ip routing-table vpn-instance VPN75 Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: VPN75 Destinations : 6 Routes : 6 Destination/Mask Proto Pre Cost Flags NextHop Interface 57.1.1.0/24 Direct 0 0 D 57.1.1.5 GigabitEthernet1/0/0 57.1.1.5/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 57.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 [R5]display ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 11 Routes : 11 Destination/Mask Proto Pre Cost Flags NextHop Interface 3.3.3.3/32 OSPF 10 2 D 45.1.1.4 GigabitEthernet0/0/0 4.4.4.4/32 OSPF 10 1 D 45.1.1.4 GigabitEthernet0/0/0 5.5.5.5/32 Direct 0 0 D 127.0.0.1 LoopBack0 34.1.1.0/24 OSPF 10 2 D 45.1.1.4 GigabitEthernet0/0/0 45.1.1.0/24 Direct 0 0 D 45.1.1.5 GigabitEthernet0/0/0 45.1.1.5/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 45.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet0/0/0 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
在PE1和PE2上面分别对B公司的分部和总部进行定义VRF
PE1上面定义B公司分部
# ip vpn-instance VPN23 ipv4-family route-distinguisher 2:3 vpn-target 200:400 export-extcommunity vpn-target 200:400 import-extcommunity #
PE2上面定义B公司总部
# ip vpn-instance VPN65 ipv4-family route-distinguisher 6:5 vpn-target 200:400 export-extcommunity vpn-target 200:400 import-extcommunity #
在PE1和PE2上面分别对B公司的分部和总部进行定义VRF调用
PE1上面定义B公司分部VRF的调用
# interface GigabitEthernet0/0/1 ip binding vpn-instance VPN23 ip address 23.1.1.3 255.255.255.0 #
PE2上面定义B公司总部VRF的调用
# interface GigabitEthernet0/0/1 ip binding vpn-instance VPN65 ip address 56.1.1.5 255.255.255.0 #
总结：此时PE1和PE2上面有三张表
一个是FIB表（全局路由表）一个是VPN13表一个是VPN23表三张表之间的关系相互独立，互不影响
6.CE1和PE1之间的路由协议
注意：CE和PE之间可以启用静态、RIP、OSPF、ISIS、BGP协议但是推荐启用BGP协议
CE1的BGP的配置
# bgp 100 peer 13.1.1.3 as-number 500 # ipv4-family unicast undo synchronization network 1.1.1.1 255.255.255.255 peer 13.1.1.3 enable #
PE1的BGP的配置
[R3-bgp]ipv4-family ? multicast Specify multicast address family unicast Specify unicast address family 默认情况你的BGP都在单播里面 vpn-instance Specify VPN instance 但是你要进入这个VPN-INSTANCE视图里面去 vpnv4 Specify VPNv4 address family [R3-bgp]ipv4-family vpn-instance VPN13 [R3-bgp-VPN13]dis this [V200R003C00] # # ipv4-family vpn-instance VPN13 peer 13.1.1.1 as-number 100 #
在PE1查看BGP VPN-instance的关系
