目标

配置LDP远端会话，需要指定远端对等体的名称和IP地址

组网模型

配置思路

• 配置IGP协议，使各节点间的IP路由可达

• 使能全局的LDP功能

• 创建MPLS LDP远端对等体

操作步骤

1. 配置各接口IP地址（略）
2. 创建IS-IS进程，接口使能IS-IS

配置CX1

CX1:
isis 1
 is-level level-2
 network-entity 49.0000.0000.0001.00
interface LoopBack112
 isis enable 1
interface Ethernet1/0/0.1
 isis enable 1

配置CX2

CX2:
isis 1
 is-level level-2
 network-entity 49.0000.0000.0002.00
interface LoopBack112
 isis enable 1
interface Ethernet1/0/0.1
 isis enable 1

1. 使能MPLS、MPLS LDP

配置CX1

CX1:
mpls lsr-id 11.11.11.149
mpls
mpls ldp
interface Ethernet1/0/0.1
 mpls
 mpls ldp

配置CX2

CX2:
mpls lsr-id 11.11.11.136
mpls
mpls ldp
interface Ethernet1/0/0.1
 mpls
 mpls ldp

1. 在远端LDP会话两端LSR上指定远端对等体及IP地址

配置CX1

CX1:
mpls ldp remote-peer CX2
 remote-ip 11.11.11.136

配置CX2

CX2:
mpls ldp remote-peer CX1
 remote-ip 11.11.11.149

1. 配置验证

配置完成后，在节点上执行show mpls ldp session命令，可以看到CX1和CX2之间的远端LDP会话状态为“Operational”。以CX1的显示为例

[~CX1]dis mpls ldp session 
 LDP Session(s) in Public Network
 Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
 An asterisk (*) before a session means the session is being deleted.
