EVPN Type5实验

Route type-5 IP prefix Route—An IP prefix route provides encoding for inter-subnet forwarding. In the control plane, EVPN type-5 routes are used to advertise IP prefixes for inter-subnet connectivity across data centers. To reach a tenant using connectivity provided by the EVPN type-5 IP prefix route, data packets are sent as Layer 2 Ethernet frames encapsulated in the VXLAN header over the IP network across the data centers.

实验拓扑

CE1 lo0.0为11.0.0.1/24

CE2 lo0.0为22.0.0.1/24

CE3 lo0.0为33.0.0.1/24

PE1 lo0.0为1.1.1.1/32

PE2 lo0.0为2.2.2.2/32

PE3 lo0.0为3.3.3.3/32

10.5.39.0/24段为管理段
