Configuring Tunnel Interfaces

This module describes the configuration of Tunnel-IPSec interfaces on the Cisco NCS 6000 Series Router.

Tunnel interfaces are virtual interfaces that provide encapsulation of arbitrary packets within another transport
protocol. The Tunnel-IPSec interface provides secure communications over otherwise unprotected public
routes.

A virtual interface represents a logical packet switching entity within the router. Virtual interfaces have a
global scope and do not have an associated location. The Cisco IOS XR Software uses the rack/slot/module/port
notation for identifying physical interfaces, but uses a globally unique numerical ID after the interface name
to identify virtual interfaces. Examples of this numerical ID are Loopback 0, Loopback 1, and Null99999.
The ID is unique for each virtual interface type so you may simultaneously have a Loopback 0 and a Null 0.

Virtual interfaces have their control plane presence on the active route processor (RP). The configuration and
control plane are mirrored onto the standby RP and, in the event of a switchover, the virtual interfaces will
move to the standby, which then becomes the newly active RP.

Subinterfaces can be physical or virtual, depending on their parent interface.

Note

Virtual tunnels are configured on any RP or distributed RP (DRP), but they are created and operate only from
the RP.

Tunnels do not have a one-to-one modular services card association.
