EVE-NG MPLS L3VPN 基本组网

1 拓扑

2 配置步骤

2.1 在MPLS节点上配置接口IP 和路由协议

PE1

interface LoopBack 0ip address 1.1.1.9 32 quitinterface GigabitEthernet4/0ip address 172.1.1.1 24quitospf 1area 1network 1.1.1.9 0.0.0.0network 172.1.1.0 0.0.0.255quitquit

P

2.2 配置MPLS  LDP

PE1

mpls lsr-id 1.1.1.9
mpls label advertise non-null
mpls ldpquitinterface GigabitEthernet4/0mpls enablempls ldp enablequit

P

mpls lsr-id 2.2.2.9
mpls label advertise non-null
mpls ldpquitinterface GigabitEthernet4/0mpls enablempls ldp enablequitinterface GigabitEthernet5/0mpls enable mpls ldp enablequit

PE2

mpls lsr-id 3.3.3.9
mpls label advertise non-null
mpls ldpquitinterface GigabitEthernet4/0mpls enablempls ldp enablequit

2.3 在PE设备上配置VPN实例

PE1

ip vpn-instance vpn1route-distinguisher 100:1vpn-target 111:1quitinterface GigabitEthernet1/0ip binding vpn-instance vpn1ip address 10.1.1.2 24quitip vpn-instance vpn2route-distinguisher 100:2vpn-target 222:2quitinterface GigabitEthernet2/0ip binding vpn-instance vpn2ip address 10.2.1.2 24quit

PE2

ip vpn-instance vpn1route-distinguisher 200:1vpn-target 111:1quitinterface GigabitEthernet1/0ip binding vpn-instance vpn1ip address 10.3.1.2 24quitip vpn-instance vpn2route-distinguisher 200:2vpn-target 222:2quitinterface GigabitEthernet2/0ip binding vpn-instance vpn2ip address 10.4.1.2 24quit

2.4 在PE与CE之间建立EBGP对等体，引入VPN路由

PE1

查看BGP状态

 2.5 在PE之间建立MP-IBGP对等体

PE1

bgp 100peer 3.3.3.9 as-number 100peer 3.3.3.9 connect-interface loopback 0address-family vpnv4peer 3.3.3.9 enablequitquit

PE2

bgp 100peer 1.1.1.9 as-number 100peer 1.1.1.9 connect-interface loopback 0address-family vpnv4peer 1.1.1.9 enablequitquit
