Preface

Simple configuration scheme , There are some differences in the actual network , No protected backup is configured in the experiment .

One 、 Tube configuration steps

1, Use of in ring equipment OSPF Conduct network management signal communication
2, Use of ring head equipment and single hanging equipment EPL Dedicated line increase VLAN Transfer to the summary device
3, Summarize equipment usage EVPL Pass through all sites VLAN
4, Use at the special line IS-IS do IGP And enable the MPLS
5, Use 2 This is a special line ,MPLS L2 And L3 A dedicated line

Two 、 The topology

1. Here's the picture

2. Introduction to equipment configuration

2.1 Communication configuration between ring node and ring head equipment
Use in the equipment room Serial simulation GCC signal communication
First configuration R2 The ring return port of IP Address （ For the node IP）

interface LoopBack0
 ip address 10.49.202.126 255.255.255.255

stay Serial Configure the borrowing ring return port address under the interface

interface Serial0/0/0
 link-protocol ppp
 ip address unnumbered interface LoopBack0

Then announce the loopback to OSPF in

ospf 1
 area 0.0.0.0
  network 10.49.202.126 0.0.0.0

R1 Of Serial The interface is also configured

interface LoopBack0
 ip address 10.49.202.62 255.255.255.255
 
 interface Serial0/0/0
 link-protocol ppp
 ip address unnumbered interface LoopBack0

Finally, we need to R1 The default route of is announced to R2 To guide the data forwarding of ring node devices

ospf 1
 default-route-advertise
 area 0.0.0.0
  network 10.49.202.62 0.0.0.0

At this point, we can make R2ping through R1

2.2 Simulate the configuration of ring head and single coupling node
R1 To configure
Use sub interface emulation EPL increase VLAN

interface GigabitEthernet0/0/0.2021
 dot1q termination vid 2021
 ip address 10.49.255.185 255.255.255.252
 arp broadcast enable

Configure a default route to the convergence switch

ip route-static 0.0.0.0 0.0.0.0 10.49.255.186

R6 Also configure sub interfaces and nodes IP And default routing

interface GigabitEthernet0/0/0.2031
 dot1q termination vid 2031
 ip address 10.49.255.177 255.255.255.252
 arp broadcast enable
interface LoopBack0
 ip address 10.49.203.62 255.255.255.255
ip route-static 0.0.0.0 0.0.0.0 10.49.255.178

2.3 Use LSW1 Switches simulate convergence devices EVPL function
To configure VLAN And bind the interface through 0/0/2 The interface transmits data to the convergence switch

interface Ethernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2021
# interface Ethernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2021 2031
# interface Ethernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan 2031

2.4 Municipal Company convergence switch configuration
First configure the corresponding device VLANIF Address

interface Vlanif2021

 ip address 10.49.128.1 255.255.255.252
# interface Vlanif501
 description to ums
 ip address 10.49.254.1 255.255.255.252

interface Ethernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 301
# interface Ethernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan 501

Configure the static routing table of each service direction

ip route-static 10.49.202.0 255.255.255.0 10.49.255.185
ip route-static 10.49.203.0 255.255.255.0 10.49.255.177
ip route-static 10.255.255.0 255.255.255.0 10.49.254.2  UMS The server IP
ip route-static 172.31.255.41 255.255.255.255 10.49.128.2    Provincial company server IP

2.5 Let's first introduce CN2 The Internet L2 Dedicated line configuration ( Go to the provincial company to choose this special line )

To configure IS-IS And enable
R3:

isis 100
 network-entity 49.0001.0001.0000.00
 
 interface GigabitEthernet0/0/0
 ip address 10.0.0.1 255.255.255.252
 isis enable 100

interface LoopBack0
 ip address 3.3.3.3 255.255.255.255
 isis enable 100

R4:

isis 100
 network-entity 49.0001.0002.0000.00
 
interface GigabitEthernet0/0/0
 ip address 10.0.0.2 255.255.255.252
 isis enable 100
 
interface LoopBack0
 ip address 4.4.4.4 255.255.255.255
 isis enable 100

Then the interface is enabled MPLS And enable the L2VPN And LDP
R3:

mpls lsr-id 3.3.3.3
mpls
# mpls l2vpn
# mpls ldp

R4:

mpls lsr-id 4.4.4.4
mpls
# mpls l2vpn
# mpls ldp

stay R3 And R4 Configure

mpls
mpls ldp

R3 Configure remote neighbors on

mpls ldp remote-peer 4.4.4.4

R4 Configure remote neighbors on

mpls ldp remote-peer 3.3.3.3

choose R3 Of G0/0/2 The port is connected to the convergence server of the municipal company , stay G0/0/2 Port configuration dedicated line service

interface GigabitEthernet0/0/2
 mpls l2vc 4.4.4.4 100 control-word
 mpls l2vpn pw bfd

R4 choose G0/0/1 Connect to the servers of provincial companies and configure special line Services

interface GigabitEthernet0/0/1
 mpls l2vc 3.3.3.3 100 control-word
 mpls l2vpn pw bfd

thus R3 Of G0/0/2 And R4 Of G0/0/1 Between them is equivalent to a network cable

2.5.1 Network management switch of municipal company LSW3 Network management switch with provincial company LSW5 Inter configuration , Route selection BGP, Later, announce the static route to BGP.
LSW3 And LSW5 To configure VLANIF Address and bind to port

LSW3: Use E0/0/3 docking R3 G0/0/2

interface Vlanif201
 description bgp
 ip address 172.0.100.1 255.255.255.252
interface Ethernet0/0/3
 port link-type access
 port default vlan 201

LSW5: Use E0/0/2 docking R4G0/0/1

interface Vlanif201
 description bgp
 ip address 172.0.100.2 255.255.255.252
interface Ethernet0/0/2
 port link-type access
 port default vlan 201

LSW3 Enable BGP And announce the static route to the device

bgp 65533
 router-id 172.0.100.1
 peer 172.0.100.2 as-number 65533
 # ipv4-family unicast
  undo synchronization
  network 10.49.128.0 255.255.128.0
  peer 172.0.100.2 enable
# ip route-static 10.49.128.0 255.255.128.0 10.49.128.1

LSW5 Enable BGP And announce the direct route to the equipment

bgp 65533
 router-id 172.0.100.2
 peer 172.0.100.1 as-number 65533
 # ipv4-family unicast
  undo synchronization
  import-route direct
  peer 172.0.100.1 enable

At this point, the ring node device can PING Tongsheng company server
2.6 Go to UMS Of L3 Dedicated line configuration or use R3 And R4
R3 To configure ： First configure a VPN INTSTANCE

ip vpn-instance UMS
 ipv4-family
  route-distinguisher 100:100
  vpn-target 200:200 export-extcommunity
  vpn-target 200:200 import-extcommunity

And then VPN Bind to sub interface

interface GigabitEthernet0/0/1.101
 dot1q termination vid 101
 ip binding vpn-instance UMS
 ip address 172.0.0.1 255.255.255.252
 arp broadcast enable

Enable BGP Of MPSL VPNV4 And introduce direct connection and static routing

 # ipv4-family unicast
  undo synchronization
  peer 4.4.4.4 enable
  peer 4.4.4.4 next-hop-local
 # ipv4-family vpnv4
  policy vpn-target
  peer 4.4.4.4 enable
 # ipv4-family vpn-instance UMS
  import-route direct
  import-route static
# ip route-static vpn-instance UMS 10.49.128.0 255.255.128.0 172.0.0.2

R4 To configure ： Also configure VPN INSTANCE

ip vpn-instance UMS
 ipv4-family
  route-distinguisher 100:101
  vpn-target 200:200 export-extcommunity
  vpn-target 200:200 import-extcommunity

take VPN Bind to sub interface

interface GigabitEthernet0/0/2.101
 dot1q termination vid 101
 ip binding vpn-instance UMS
 ip address 172.0.10.1 255.255.255.252
 arp broadcast enable

Also enable BGP MPLS VPNV4 And introduce the route into

bgp 65535
 router-id 4.4.4.4
 peer 3.3.3.3 as-number 65535
 peer 3.3.3.3 connect-interface LoopBack0
 # ipv4-family unicast
  undo synchronization
  peer 3.3.3.3 enable
  peer 3.3.3.3 next-hop-local
 # ipv4-family vpnv4
  policy vpn-target
  peer 3.3.3.3 enable
 # ipv4-family vpn-instance UMS
  import-route direct
  import-route static
# ip route-static vpn-instance UMS 10.255.255.0 255.255.255.0 172.0.10.2

thus L3 The special line has been opened

2.7 Go to UMS Of 2 Switches LSW4 LSW6 To configure

LSW4 To configure ：
To configure 2 individual VLANIF The communication address is bound to the port to the dedicated line router and the municipal convergence switch
