Support for interprovider and carrier-of-carrier VPNs (Junos fusion for provider edge)—Starting in Junos OS Release 21.1R1, Junos fusion for provider edge supports Interprovider and Carrier-of-Carrier VPNs. The Carrier-of-Carrier VPN service describes a hierarchical VPN (also known as a recursive VPN) model where one carrier (VPN service customer) transports its VPN traffic inside another carrier’s VPN (VPN service provider). Junos fusion for provider edge currently supports provider edge (PE) routers for VPN service customers. In Junos OS Release 21.1R1, we introduce support for PE routers for VPN service providers along with VPN service customers.
Interprovider VPNs provide connectivity between different service providers that are using separate autonomous systems (ASs) or one service provider that is using different ASs for different geographic locations. For Interprovider VPNs, Junos fusion for provider edge supports only intra-AS connection on an AS boundary router (ASBR) to the extended port.
