篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了华为运营商级路由器配置示例 | EVdPdNd VPLS over SRv6 TE Policy(静态配置)相关的知识,希望对你有一定的参考价值。

组网需求

如图1所示:PE1、P和PE2属于同一自治系统,要求它们之间通过IS-IS协议达到IPv6网络互连。然后在PE1和PE2之间通过建立双向SRv6 TE Policy承载EVPN E-LAN业务。

图1 配置EVPN VPLS over SRv6 TE Policy组网图

配置思路

  1. 使能PE1、P和PE2各接口的IPv6转发能力,配置各接口的IPv6地址。
  2. 在PE1、P和PE2上使能IS-IS,配置Level级别,指定网络实体。
  3. 在PE设备上配置BD模式的EVPN实例,并将相应的BD绑定到接入侧子接口。
  4. 在PE设备之间建立BGP EVPN对等体关系。
  5. 在PE1、P和PE2上配置SRv6 SID,配置IS-IS的SRv6能力。同时在PE1和PE2上配置VPN私网路由携带SID属性。
  6. 在PE1和PE2上配置SRv6 TE Policy。
  7. 在PE1和PE2上配置隧道策略,引入私网流量。

操作步骤

1.使能各接口的IPv6转发能力,配置各接口的IPv6地址

# 配置PE1。P和PE2设备的配置过程与PE1类似,不再赘述,详情可参考配置文件。

<HUAWEI> system-view
[~HUAWEI] sysname PE1
[*HUAWEI] commit
[~PE1] interface gigabitethernet 1/0/0
[~PE1-GigabitEthernet1/0/0] ipv6 enable
[*PE1-GigabitEthernet1/0/0] ipv6 address 2001:DB8:10::1 64
[*PE1-GigabitEthernet1/0/0] quit
[*PE1] interface LoopBack 1
[*PE1-LoopBack1] ip address 1.1.1.1 32
[*PE1-LoopBack1] ipv6 enable
[*PE1-LoopBack1] ipv6 address 2001:DB8:1::1 128
[*PE1-LoopBack1] quit
[*PE1] commit

由于需要为EVPN源地址准备IPv4地址,因此这里Loopback接口还需配置IPv4地址。

2.配置IS-IS

# 配置PE1。

[~PE1] isis 1
[*PE1-isis-1] is-level level-1
[*PE1-isis-1] cost-style wide
[*PE1-isis-1] network-entity 10.0000.0000.0001.00
[*PE1-isis-1] ipv6 enable topology ipv6
[*PE1-isis-1] quit
[*PE1] interface gigabitethernet 1/0/0
[*PE1-GigabitEthernet1/0/0] isis ipv6 enable 1
[*PE1-GigabitEthernet1/0/0] quit
[*PE1] interface loopback1
[*PE1-LoopBack1] isis ipv6 enable 1
[*PE1-LoopBack1] commit
[~PE1-LoopBack1] quit

# 配置P。

[~P] isis 1 
[*P-isis-1] is-level level-1
[*P-isis-1] cost-style wide
[*P-isis-1] network-entity 10.0000.0000.0002.00
[*P-isis-1] ipv6 enable topology ipv6
[*P-isis-1] quit
[*P] interface gigabitethernet 1/0/0
[*P-GigabitEthernet1/0/0] isis ipv6 enable 1
[*P-GigabitEthernet1/0/0] quit
[*P] interface gigabitethernet 2/0/0
[*P-GigabitEthernet2/0/0] isis ipv6 enable 1
[*P-GigabitEthernet2/0/0] quit
[*P] interface loopback1
[*P-LoopBack1] isis ipv6 enable 1
[*P-LoopBack1] commit
[~P-LoopBack1] quit

# 配置PE2。

[~PE2] isis 1
[*PE2-isis-1] is-level level-1
[*PE2-isis-1] cost-style wide
[*PE2-isis-1] network-entity 10.0000.0000.0003.00
[*PE2-isis-1] ipv6 enable topology ipv6
[*PE2-isis-1] quit
[*PE2] interface gigabitethernet 1/0/0
[*PE2-GigabitEthernet1/0/0] isis ipv6 enable 1
[*PE2-GigabitEthernet1/0/0] quit
[*PE2] interface loopback1
[*PE2-LoopBack1] isis ipv6 enable 1
[*PE2-LoopBack1] commit
[~PE2-LoopBack1] quit

配置完成后,可按如下指导检查IS-IS是否配置成功。

[~PE1] display isis peer

3.在PE设备上配置BD模式的EVPN实例,并将相应的BD绑定到接入侧子接口

# 配置PE1。

[~PE1] evpn source-address 1.1.1.1
[*PE1] evpn vpn-instance evrf1 bd-mode
[*PE1-evpn-instance-evrf1] route-distinguisher 100:1
[*PE1-evpn-instance-evrf1] vpn-target 1:1
[*PE1-evpn-instance-evrf1] quit
[*PE1] bridge-domain 100
[*PE1-bd100] evpn binding vpn-instance evrf1
[*PE1-bd100] quit
[*PE1] interface gigabitethernet 2/0/0.1 mode l2
[*PE1-GigabitEthernet2/0/0.1] encapsulation dot1q vid 1
[*PE1-GigabitEthernet2/0/0.1] rewrite pop single
[*PE1-GigabitEthernet2/0/0.1] bridge-domain 100
[*PE1-GigabitEthernet2/0/0.1] quit
[*PE1] commit

# 配置PE2。

[~PE2] evpn source-address 3.3.3.3
[*PE2] evpn vpn-instance evrf1 bd-mode
[*PE2-evpn-instance-evrf1] route-distinguisher 200:1
[*PE2-evpn-instance-evrf1] vpn-target 1:1
[*PE2-evpn-instance-evrf1] quit
[*PE2] bridge-domain 100
[*PE2-bd100] evpn binding vpn-instance evrf1
[*PE2-bd100] quit
[*PE2] interface gigabitethernet 2/0/0.1 mode l2
[*PE2-GigabitEthernet2/0/0.1] encapsulation dot1q vid 1
[*PE2-GigabitEthernet2/0/0.1] rewrite pop single
[*PE2-GigabitEthernet2/0/0.1] bridge-domain 100
[*PE2-GigabitEthernet2/0/0.1] quit
[*PE2] commit

4.在PE设备之间建立BGP EVPN对等体关系

# 配置PE1。

[~PE1] bgp 100
[*PE1-bgp] router-id 1.1.1.1
[*PE1-bgp] peer 2001:DB8:3::3 as-number 100
[*PE1-bgp] peer 2001:DB8:3::3 connect-interface loopback 1
[*PE1-bgp] l2vpn-family evpn
[*PE1-bgp-af-evpn] peer 2001:DB8:3::3 enable
[*PE1-bgp-af-evpn] peer 2001:DB8:3::3 advertise encap-type srv6
[*PE1-bgp-af-evpn] quit
[*PE1-bgp] quit
[*PE1] commit

# 配置PE2。

[~PE2] bgp 100
[*PE2-bgp] router-id 3.3.3.3
[*PE2-bgp] peer 2001:DB8:1::1 as-number 100
[*PE2-bgp] peer 2001:DB8:1::1 connect-interface loopback 1
[*PE2-bgp] l2vpn-family evpn
[*PE2-bgp-af-evpn] peer 2001:DB8:1::1 enable
[*PE2-bgp-af-evpn] peer 2001:DB8:1::1 advertise encap-type srv6
[*PE2-bgp-af-evpn] quit
[*PE2-bgp] quit
[*PE2] commit

配置完成后,在PE设备上执行display bgp evpn peer命令,可以看到PE之间的BGP EVPN对等体关系已建立,并达到Established状态。以PE1的显示为例:

[~PE1] display bgp evpn peer                             

 BGP local router ID : 1.1.1.1                          
 Local AS number : 100                                  
 Total number of peers : 1                 Peers in established state : 1       

  Peer                             V          AS  MsgRcvd  MsgSent  OutQ  Up/Down       State  PrefRcv                              
  2001:DB8:3::3                    4         100       31       34     0 00:18:39 Established        1  

5.配置SRv6 SID,同时在PE上配置VPN私网路由携带SID属性

# 配置PE1。

8.配置CE接入各自的PE

# 配置CE1。

[~CE1] interface gigabitethernet1/0/0
[~CE1-GigabitEthernet1/0/0] undo shutdown
[*CE1-GigabitEthernet1/0/0] quit
[*CE1] interface gigabitethernet1/0/0.1
[*CE1-GigabitEthernet1/0/0.1] vlan-type dot1q 1
[*CE1-GigabitEthernet1/0/0.1] ip address 10.1.1.1 255.255.255.0
[*CE1-GigabitEthernet1/0/0.1] quit
[*CE1] commit

# 配置CE2

[~CE2] interface gigabitethernet1/0/0
[~CE2-GigabitEthernet1/0/0] undo shutdown
[*CE2-GigabitEthernet1/0/0] quit
[*CE2] interface gigabitethernet1/0/0.1
[*CE2-GigabitEthernet1/0/0.1] vlan-type dot1q 1
[*CE2-GigabitEthernet1/0/0.1] ip address 10.1.1.2 255.255.255.0
[*CE2-GigabitEthernet1/0/0.1] quit
[*CE2] commit

9.检查配置结果

在PE上通过命令display segment-routing ipv6 local-sid end-dt2u | end-dt2ul | end-dt2m forwarding,查看SRv6的Local SID表信息。以PE1为例:

[~PE1] display segment-routing ipv6 local-sid end-dt2m forwarding

                    My Local-SID End.DT2M Forwarding Table
                    --------------------------------------

Total SID(s): 1 
[~PE1] display segment-routing ipv6 local-sid end-dt2u forwarding

                    My Local-SID End.DT2U Forwarding Table 
                    --------------------------------------                      

SID             : 2001:DB8:11::1:0:5C/128                      FuncType : End.DT2U                                                  
Bridge-domain ID: 100                                   
LocatorName     : PE1                                          LocatorID: 5     

Total SID(s): 1

在PE上通过配置命令display bgp evpn all routing-table,可以看到远端发来的EVPN路由。以PE1为例:

[~PE1] display bgp evpn all routing-table

 Local AS number : 100                                  

 BGP Local router ID is 1.1.1.1                         
 Status codes: * - valid, > - best, d - damped, x - best external, a - add path,
               h - history,  i - internal, s - suppressed, S - Stale       
               Origin : i - IGP, e - EGP, ? - incomplete

在CE上执行ping命令,同一VPN的CE能够相互Ping通,例如:

[~CE1] ping 10.1.1.2
