配置跨域Seamless MPLS+HVPN示例

配置跨域Seamless MPLS+HVPN示例

组网需求

图7-14所示的网络中,接入层(Access)、汇聚层(Aggregation)和核心层(Core)网络处于不同AS内。为了实现基站(NodeB)与MME/SGW互通并提供VPN服务,用户希望将MPLS技术扩展至接入层网络,在接入层、汇聚层和核心层网络中部署一条完整的LSP,提供一种端到端的服务,从而简化端到端的业务配置和网络管理,则可以在该组网内部署跨域Seamless MPLS。同时,用户希望能够在接入层根据网络设备的业务能力,定制不同层次的设备容量,从而降低组网成本,此时可以在接入层部署HVPN。

图7-14  配置跨域Seamless MPLS+HVPN组网

配置思路

采用如下的思路配置跨域Seamless MPLS+HVPN:

  1. 在各个网络层内配置IGP协议,实现各自网络层内互通。

  2. 在各个设备上配置MPLS基本能力和MPLS LDP,在各个网络层内建立MPLS LSP。

  3. 在汇聚层和核心层内分别建立IBGP邻居,并使能标签路由交换能力。

  4. 在AGG_ASBR和Core_ASBR间建立EBGP邻居,并使能标签路由交换能力。

  5. 在CSG以外的设备上配置路由策略建立BGP LSP:在BGP LSP的起始节点上,需要为向下游发布的路由分配MPLS标签;在BGP LSP的中间节点上,如果从上游收到带标签的IPv4路由,则需要为其重新分配MPLS标签,然后向下游发布。

  6. 在AGG和MASG间建立MP-EBGP邻居。

  7. 在CSG和AGG间建立MP-IBGP邻居。

  8. 将AGG配置成路由反射器。

  9. 在CSG、AGG和MASG上配置VPN实例。

  10. 在AGG上配置缺省路由和IP地址前缀列表,使AGG仅向CSG发送一条缺省路由。

操作步骤

  1. 在设备上创建VLAN、VLANIF接口,配置VLANIF接口的IP地址,并将相应的物理接口加入到VLAN

    # 配置CSG。AGG、AGG_ASBR、Core_ASBR和MASG的配置与CSG类似,不再赘述。

    [Core_ASBR-bgp] quit

    在AGG或MASG上执行display mpls lsp命令,可以看到LSP的信息。

    以AGG的显示为例:

    [AGG] display mpls lsp
    -------------------------------------------------------------------------------
                     LSP Information: BGP  LSP
    -------------------------------------------------------------------------------

    2.2.2.9/32         3/NULL        -/-             
    1.1.1.9/32         NULL/3        -/Vlanif100  
    1.1.1.9/32         4099/3        -/Vlanif100     

  8. 在CSG和AGG间建立MP-IBGP邻居

    # 配置CSG。

    [CSG] bgp 100
    [CSG-bgp] peer 2.2.2.9 as-number 100
    [CSG-bgp] peer 2.2.2.9 connect-interface LoopBack 1
    [CSG-bgp] network 1.1.1.9 255.255.255.255
    [CSG-bgp] ipv4-family vpnv4
    [CSG-bgp-af-vpnv4] peer 2.2.2.9 enable
    [CSG-bgp-af-vpnv4] policy vpn-target
    [CSG-bgp-af-vpnv4] quit
    [CSG-bgp] quit

    # 配置AGG。

    [AGG] bgp 100
    [AGG-bgp] peer 1.1.1.9 as-number 100
    [AGG-bgp] peer 1.1.1.9 connect-interface LoopBack 1
    [AGG-bgp] ipv4-family vpnv4
    [AGG-bgp-af-vpnv4] peer 1.1.1.9 enable
    [AGG-bgp-af-vpnv4] quit
    [AGG-bgp] quit

  9. 将AGG设备配置成路由反射器,通过路由反射使CSG和MASG获得对方的Loopback路由

    # 配置AGG。

    [AGG] bgp 100
    [AGG-bgp] peer 1.1.1.9 reflect-client
    [AGG-bgp] peer 1.1.1.9 next-hop-local
    [AGG-bgp] quit

  10. 配置VPN实例并绑定接口

    # 配置CSG。

    [CSG] ip vpn-instance vpn1
    [CSG-vpn-instance-vpn1] ipv4-family
    [CSG-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:1
    [CSG-vpn-instance-vpn1-af-ipv4] vpn-target 1:1
    [CSG-vpn-instance-vpn1-af-ipv4] quit
    [CSG-vpn-instance-vpn1] quit
    [CSG] bgp 100
    [CSG-bgp] ipv4-family vpn-instance vpn1
    [CSG-bgp-vpn1] import-route direct
    [CSG-bgp-vpn1] quit
    [CSG-bgp] quit
    [CSG] interface vlanif 10
    [CSG-Vlanif10] ip binding vpn-instance vpn1
    [CSG-Vlanif10] ip address 192.168.1.1 24
    [CSG-Vlanif10] quit

    # 配置MASG。

    [MASG] ip vpn-instance vpn1
    [MASG-vpn-instance-vpn1] ipv4-family
    [MASG-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:1
    [MASG-vpn-instance-vpn1-af-ipv4] vpn-target 1:1
    [MASG-vpn-instance-vpn1-af-ipv4] quit
    [MASG-vpn-instance-vpn1] quit
    [MASG] bgp 200
    [MASG-bgp] ipv4-family vpn-instance vpn1
    [MASG-bgp-vpn1] import-route direct
    [MASG-bgp-vpn1] quit
    [MASG-bgp] quit
    [MASG] interface vlanif 20
    [MASG-Vlanif20] ip binding vpn-instance vpn1
    [MASG-Vlanif20] ip address 192.168.2.1 24
    [MASG-Vlanif20] quit

    # 配置AGG。

    [AGG] ip vpn-instance vpn1
    [AGG-vpn-instance-vpn1] ipv4-family
    [AGG-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:1
    [AGG-vpn-instance-vpn1-af-ipv4] vpn-target 1:1
    [AGG-vpn-instance-vpn1-af-ipv4] quit
    [AGG-vpn-instance-vpn1] quit

  11. 在AGG上配置缺省路由和IP地址前缀列表,使AGG仅向CSG发送一条缺省路由

    # 配置AGG。

    [AGG] ip route-static vpn-instance vpn1 0.0.0.0 0.0.0.0 NULL0 
    [AGG] ip ip-prefix default index 10 permit 0.0.0.0 0
    [AGG] bgp 100
    [AGG-bgp] ipv4-family vpnv4
    [AGG-bgp-af-vpnv4] peer 1.1.1.9 ip-prefix default export
    [AGG-bgp-af-vpnv4] quit
    [AGG-bgp] ipv4-family vpn-instance vpn1
    [AGG-bgp-vpn1] network 0.0.0.0 0
    [AGG-bgp-vpn1] quit
    [AGG-bgp] quit

    # 配置CSG。

    [CSG] bgp 100
    [CSG-bgp] ipv4-family vpn-instance vpn1
    [CSG-bgp-vpn1] import-route direct
    [CSG-bgp-vpn1] quit
    [CSG-bgp] quit

  12. 检查配置结果

    配置完成后,CSG上没有到达MME/SGW的私网路由,但有一条下一跳为AGG的缺省路由,且CSG可以Ping通到达MME/SGW的路由。

    以CSG的显示为例:

    [CSG] display ip routing-table vpn-instance vpn1
    Route Flags: R - relay, D - download to fib
    ------------------------------------------------------------------------------
    Routing Tables: vpn1
             Destinations : 3        Routes : 3
