MPLS Stitching For Virtual Machine Connections

By using MPLS, the stitching feature of Junos OS provides connectivity between virtual machines on opposite sides of data center routers. An external controller, programmed in the data-plane, assigns MPLS labels to both virtual machines and servers. Then, the signaled MPLS labels are used between the data center routers, generating static link switched paths (LSPs), resolved over RSVP or LDP, to provide the routes dictated by the labels. The new CLI command stitch, located under the LSP transit command, provides this capability.
