MSR路由器MPLS IPTN功能的配置

MSR路由器

MPLS IPTN功能的配置

关键字：MSR;MPLS;Static-lsp;IPTN

一、组网需求：

PEA、P、PEB建立一条PEA到PEB的静态LSP，PEA上配置将携带IPTN标签的流量引入静态LSP

设备清单：MSR路由器3台

二、组网图：

三、配置步骤：

适用设备和版本：MSR、Version 5.20, Beta 1105后所有版本。

PEA配置

#  router id 1.1.1.1 # mpls lsr-id 1.1.1.1 # mpls # interface Ethernet0/0  port link-mode route  description connects to p  ip address 1.2.0.1 255.255.255.0  mpls # interface Ethernet0/1  port link-mode route  description iptn  ip address 1.0.0.1 255.255.255.0  mpls # interface LoopBack0  ip address 1.1.1.1 255.255.255.255 # ospf 1  area 0.0.0.0   network 1.1.1.1 0.0.0.0   network 1.2.0.0 0.0.0.255 #  //定义一条静态ingress LSP，目标是PEB的环回地址  static-lsp ingress slsp destination 3.3.3.3 32 nexthop 1.2.0.2 out-label 100 //定义iptn引入标签 iptn iptnA binding static-lsp-name slsp label 50 #

P配置

# router id 2.2.2.2 # mpls lsr-id 2.2.2.2 # mpls # interface Ethernet0/0  port link-mode route  description connects to peA  ip address 1.2.0.2 255.255.255.0  mpls # interface Ethernet0/1  port link-mode route  description connects to peB  ip address 2.3.0.2 255.255.255.0  mpls # interface LoopBack0  ip address 2.2.2.2 255.255.255.255 # ospf 1  area 0.0.0.0   network 2.2.2.2 0.0.0.0   network 1.2.0.0 0.0.0.255   network 2.3.0.0 0.0.0.255 # //建立一条静态transit LSP static-lsp transit slsp incoming-interface Ethernet0/0 in-label 100 nexthop 2.3.0.3 out-label 200 #

PEB配置

# router id 3.3.3.3 # mpls lsr-id 3.3.3.3 # mpls # interface LoopBack0  ip address 3.3.3.3 255.255.255.255 # interface Ethernet0/0  port link-mode route  description connects to p  ip address 2.3.0.3 255.255.255.0  mpls # interface Ethernet0/1  port link-mode route  description iptn  mpls # ospf 1  area 0.0.0.0   network 3.3.3.3 0.0.0.0   network 2.3.0.0 0.0.0.255 #  //定义一条静态egress LSP  static-lsp egress slsp incoming-interface Ethernet0/0 in-label 200 #

 

四、配置关键点：

1) MPLS网络的静态LSP配置需要前后匹配；

2) PEA各个接口都需要使能MPLS，以接收IPTN流量。
