Abstract
Techniques are described that allow fast path delivery of content from content data networks directly to metro transport networks so as to bypass Internet service provider (ISP) networks. The metro transport network is positioned between subscriber devices and an Internet service provider network that authenticates the subscriber devices and allocates respective layer three (L3) addresses from an Internet Protocol (IP) network address prefix assigned to the Internet service provider network. Routes within the metro transport network, including an access router, ISP-facing provider edge routers and one or more peering routers, establish an EVPN within the metro transport network. The access router outputs, within the EVPN and to the peering router, an EVPN route advertisement that advertises network address reachability information of the subscriber devices (e.g., the IP network address prefix or MAC/IP address of the subscriber devices) on behalf of the Internet service provider network.
