I showed how to use MPLS transport tunnel signaling protocols such as LDP and RSVP-TE to establish MPLS transport tunnels to carry Overlay network services such as ePipe, VPLS and VPRN (L3VPN) for Nokia, Cisco and Juniper routers in my earlier articles. RSVP-TE offers Traffic Engineering (TE) capability where the path of an LSP can … Continue reading Segment Routing
