Enabling Network Virtualization Satellite Mode on the Cisco
ASR 903 Router
This document describes how to enable Network Virtualization Satellite Mode on the Cisco ASR 903 Router and contains the
following sections:
Overview
The Satellite Network Virtualization (nV) feature allows you to configure remote routers to act as remote virtual switch interfaces
on the ASR 9000. IOS XE Release 3.8 introduces support for nV mode on the Cisco ASR 903 Router, allowing it to act as a satellite
nV device, controlled by the ASR 9000 using the IOS XR CLI.
Limitations
The following limitations apply when enabling nV satellite mode on the Cisco ASR 903 Router.
• An in-service software upgrade (ISSU) is not supported while the router is acting as an nV satellite device.
• RSP redundancy is not supported while the router is acting as a satellite nV device.
• Online Insertion and Removal (OIR) of interface modules (IMs) is not supported when the router is operating in nV satellite
mode.
• Supported connections to the satellite host include
◦ Gigabit Ethernet interfaces
◦ Ethernet transported over optical interfaces
◦ 10 Gigabit Ethernet interfaces (slots 1 and 2 only)
Other connection types are not supported.
• Local switching on the satellite device is not supported. The packets are always sent to the host for layer 2 and layer 3 switching.
• Network clocking is not supported when the router is operating in nV satellite mode.
• Reverting from a satellite mode image to the base image requires that you download the original image using TFTP; an inband
download is not supported. For more information, see
