ROUTE SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2019/001397
Kind Code:
A1
Abstract:
In an example of a route synchronization method, a first VTEP in a first EVPN learns the address of a first VM connected with the first VTEP; the learned address of the first VM is transmitted through the first EVPN route with a second VTEP connected with the first VTEP, the second VTEP belonging to any one of the first EVPN and a second EVPN at a different level with the first EVPN; a second EVPN route is received, the second EVPN route carrying the address of a second VM and a destination IP address used to establish a VXLAN tunnel; a routing table entry containing the address of the second VM is created, next hop information included in the routing table entry being the destination IP address carried in the second EVPN route; and a VXLAN tunnel is established between the first VTEP and the VTEP identified by the destination IP address carried in the second EVPN route.
