Configuring the Satellite Network Virtualization (nV) System
Multicast IRB
Multicast IRB provides the ability to route multicast packets between a bridge group and a routed interface
using a bridge-group virtual interface (BVI). It can be enabled with multicast-routing. THE BVI is a virtual
interface within the router that acts like a normal routed interface. For details about BVI, refer Cisco ASR 9000
Series Aggregation Services Router Interface and Hardware Component Configuration Guide
BV interfaces are added to the existing VRF routes and integrated with the replication slot mask. After this
integration, the traffic coming from a VRF BVI is forwarded to the VPN.
Quality of Service
Most Layer-2, Layer-3 QoS and ACL features are supported on Satellite Ethernet interfaces that are similar
to normal physical Ethernet interfaces, with the exception of any ingress policy with a queuing action. However,
for QoS, there may be some functional differences in the behavior because in the Cisco IOS XR Software
Release 4.2.x, user-configured MQC policies are applied on theCisco ASR 9000 Series Router, and not on
the satellite switch interfaces.
For more detailed information on QoS Offload and QoS policy attributes, features, and their configuration,
see Cisco ASR 9000 Series Aggregation Services Router Modular Quality of Service Configuration Guide .
User-configured QoS policies are independent of any default port level QoS that are applied in order to
Note
handle IC link congestion and oversubscription scenarios. In addition to the default port-level QoS applied
on the satellite system ports, there is also some default QoS applied on the Cisco ASR 9000 Series Router
side, to the ingress and egress traffic from and to the Satellite Ethernet ports.
Cluster Support
A cluster of Cisco ASR 9000 Series Routers is supported along with the satellite mode. A single cluster system
can act like one logical Cisco ASR 9000 Series Router host system for a group of satellite switches. A satellite
switch can also have some ICLs connect to rack 0 and other ICLs connect to rack 1 of a cluster system.
For more information, see Configuring the nV Edge System on the Cisco ASR 9000 Series Router chapter.
The Satellite Ethernet interfaces cannot be used as cluster inter-rack links.
Note
Time of Day Synchronization
The Time of Day parameter on the satellite switch is synchronized with the time of day on the host. This
ensures that time stamps on debug messages and other satellite event logs are consistent with the host, and
with all satellite switches across the network. This is achieved through the SDAC Discovery Protocol from
the host to the satellite switch when the ICLs are discovered.
