A tunnel interface in a J-series Services Router running JUNOS software supports many of the same CoS features as a physical interface. A tunnel interface is a virtual or logical interface on a J-series router. It creates a virtual point-to-point link between two J-series routers at remote points over an IP network.
For example, you can configure CoS features for generic routing encapsulation (GRE) and IP-IP tunnel interfaces. Tunneling protocols encapsulate packets inside a transport protocol.
GRE or IP-IP tunnels are used with services like IPsec and NAT to set up point-to-point VPNs. JUNOS software allows you to enable CoS queuing, scheduling, and shaping for traffic exiting through these tunnel interfaces.
