This feature was introduced on the Cisco ASR 9000 Series Router.
#Software loopback interface 1 software#
The configuration and control plane are mirrored onto the standby RSP and, in the event of a failover, the virtual interfaces move to the ex-standby, which then becomes the newly active RSP.įeature History for Configuring Loopback and Null Interfaces on Cisco IOS XR Software Loopback and null interfaces have their control plane presence on the active route switch processor (RSP). The ID is unique per virtual interface type to make the entire name string unique such that you can have both Loopback 0 and Null 0. Examples are Loopback 0, Loopback 1, and Loopback 99999. Virtual interfaces have instead a globally unique numerical ID after their names. Virtual interfaces have a global scope and do not have an associated location. Loopback and null interfaces are considered virtual interfaces.Ī virtual interface represents a logical packet switching entity within the router. This module describes the configuration of loopback and null interfaces on the Cisco ASR 9000 Series Aggregation Services Routers.
